Viscosity test method.

1 .Taking sample

Strictly follow the sample taking processure,firstly make sure to take the adhesive from same reaction pot to make sure the sample stable ability(processure is:taking sample from the middle pallet on the same pot adhesive)

2.Making sample.

Glue make into round shape,diameter less than inner dia than glue tank,the glue sample taking amount is 10±0.5g(#27 rotor,) 5±0.5g(21#rotor),when using other rotors,you need to take 10g melted and take into rotor,and input several times with little amount,the sample amount is not less than the rotor basic measure level.

3.Putting sample

Open the power and set temperature,put the glue into the glue bucket and heat it,after it is melted,put the sample and take rotor, put the temperature cover( remark: be cautious that when putting the sample ,do put in the rotor in the glue bucket bottom in time,to prevent sample overflow after heating, and wait till the temperature stable as setting target.

4.reading data.

  • After 25mins,the sample was evenly heated,hang the rotor on the inductor,adjust  viscosimeter, vacuum cup level, press start button to test. Adjust position of the vacuum cup,to make sure hanger of rotor won’t touch vacuum cup cover. When 3 of them in same level at same time,firstly  rotering 30seconds for rotor till it is stable and start reading data. And write down the visicosity in this temperature.

After testing ,reset temperature ,wait 15mins,and read it again.

5. After testing ,put out the rotor and clear it with paper,and make the rotor in storage shelf.

Taking out the glue bucket and take some of glue to the ring of softening point tester ,the leftover put to recycling box,and clear glue left in glue bucket with knife; clear with paper,and put in the same type of adhesive and start test.If testing different adhesive,or using many times,should linger glue till it getting cool,and put it sink in to xylene oil . Using a sharp knife blunt carbon deposit from the inner side of  Vacuum cup.


  1. You should wear gloves when using rotor, use clothing when taking glue bucket to prevent heating.
  2. when using different type of adhesive,glue bucket cannot mix together, one glue bucket can only test one model .

don’t touch the connection line between vacuum cup with the the The thermostat .

Exception handling:

  1. temperature control not correct, you should adjust the temperature tester and reset  the data of the thermostat
  2. if the thermostat didn’t show no. correctly,pls inspect if the lines connect properly.
  3. If glue bucket stucked,please firstly clear the glue inside.and cool down the bucket,and heating fastly.and then taking the glue bucket ,if failed, heating glue bucket to 180degreeC and put in half bottle water and fastly taking out the glue bucket. If the glue bucket is out of shape, it should not be used again

Softening point test method:

1.Making sample

Injecting the glue in the ring of the tester,after cooling down,cut the leftover,to make sure the glue face in same edge of ring egde.


Firstly cooling down the sample at least 1 hour,and take the sample on the  Measurement bracket, put on the steel ball locater and steel ball,and put into the measuring cup.

Open the power, stable the temperature 1-2mins,and press start button to test.When the glue getting softening,steel ball dropping into button dam board, start to record it,this temperature is the softening point.

3.after testing,turn off the power, and take out steel ball with tweezer,sample ring and the ball locator,try to prevent glue linger in the vacuum cup and measurement bracket,. Clear the  glue from steel ball ,ring and  steel ball locator.If the glue linger on the bracket and hard to clear out ,you should srape with tweezer or paper when it still heating.


  1. when making sample,the leftover glue should be cut off,if the glue is less,should remake the sample again.
  2. the glue must be cool down first.
  3. The glycerin in the Measuring cup should cool down till room temperature(maximum 3℃ higher than room temperature)

steel ball should put in the right place to prevent it roller and get scratcher.

  1. the rotor speed should be medium, when the temperature increase the glycerin is geeting less,the roter speed would get faster, you should slow down it, to prvent rotering too fast and loose its stiring effection.
  2. all the glue in the stands, The thermometer should clear.
  3. Amount of glycerin should be at about 800mL, temperature increase speed should be 5℃±0.5℃。 you should inspect these 2 point to make sure its up to standard. If these 2 data is not in same level,subject to temperature increase speed as priority, and adjust amount of glycerin.

Hot Melt Adhesive Manufacturers Revolutionized The Packaging Industry   no comments

Almost 50 years ago hot melt adhesives manufacturer revolutionized the hot melt equipment packaging industry. These special Hot Melt Adhesive are thermoplastic compounds or polymers that solid by nature at normal temperature, in liquid form upon heating, and again become solid after cooling to create a bond. Hot melts save power because they need less energy to melt than water or solvent based adhesive that need to dry or cure. They also save your money on solvent extraction equipment, associated with solvent based adhesive. Previously, almost all packaging companies were using case erectors and sealers in their packaging processes. With the help of the latest and the newest technology, now hot melt manufacturer companies from worldwide easily moved to it because new technologies allowed quick sealing and closing of containers. Mainly, these adhesives are low-temperature synthetics that form very quickly with the loss of temperature.

They bond very efficiently to paper-based substrates used in corrugated packaging. In starting phase of their business time these companies prefer to work on cost cutting but now with the help of new hot melt equipment technologies and factory trained special staff the ranges of prices, sizes, open and close times, set times, there are now many more opportunities where applicator, applies the adhesive in a circulars than ever for packaging any adhesives within a lower cost of production. Our hot melt systems and glue applicators are made with accuracy, reliability and repeatability for a large number of applications. These adhesives can be easily applied with a variety of parts and systems. The application equipment is approximately as different as the adhesives. Primary these systems fall into two basic types. Hand held, using sticks slugs or cartridges, and bulk systems which can usually accept a wide variety of forms of adhesives.

Handguns are used basically for low volume applications with low viscosity adhesives. Roll coating machines are generally used for the application of a liquid to the surface of a part. Extruders process multiple kinds of materials in different volumes or quantities and in many ways, from single packer, twin packer, horizontal feed, terrier bottom feeder and twin screw extruders. Swirl spray systems take the adhesive and pump it under pressure from a bulk heating tank through either a stationary or hand held applicator, which applies the adhesive in a circular pattern. Fabrication guns offer non-contact lamination capabilities by oscillating small fibers of the adhesive at the very high speed concurrently. The best part of these systems precisely controls the temperature of the hot melt – allowing for their precise application. Adhesives or glues are present in so many forms, depending on the equipment they are to pertain with or the specific application they are being used for. These forms include basically sticks, chunks, slats, powders and others.

Using High Viscosity Adhesive   no comments

Dermabond is composed of 2-octyl cyanoacrylate which is to be used as a topical skin Adhesive. Unlike other formulations of cyanoacrylate which need to be injected onto the wound edges, use of cyanoacrylate in the form of Dermabond Propen allows it to be applied to the skin surface after keeping the wound edges approximated together. It is important that there should be no or very minimal tension on the wound edges to allow Dermabond to act as adhesive. High Viscosity Dermabond adhesive is six times thicker than the original Dermabond adhesive. The viscosity of the original Dermabond adhesive is slightly greater than water, while High Viscosity Dermabond adhesive has a syrup-like viscosity. Advantages Of Dermabond Propen And How Does It Compare To Sutures? Dermabond skin adhesive when used to approximate edges of skin incisions, gives an extremely good cosmetic result.

The only pre-requisite is that skin edges should not be under any tension; else they will separate away from each other during the application of Dermabond, allowing the liquid to enter deeper tissues. Using Dermabond Propen makes the application of Dermabond simpler than using the vial as the ability to hold the applicator like a pen makes it easy to apply the adhesive over the skin. It is necessary that sutures be taken in the subdermal region of the wound to keep the skin edges close to each other and allow good sealing with Dermabond. Without these sutures the wound is likely to gape after application of Dermabond. When Ethilon or other suture materials are used to close skin incisions, the entry and exit points leave scars like alternating spots outside of the scar. Use of Dermabond does not have this problem and leaves a seamless scar in 10-14 days. Tips On Using Surgical Supplies And Ethicon Dermabond Propen And Method Of Use: Dermabond is supplied in a vial of 0.5 ml of violet coloured liquid.

This vial is positioned inside the Dermabond Propen for use. Initially the skin is patted dry with a mop or gauze piece. Dermabond hardens up quicker when used on wet surfaces and in the presence of disinfectants like alcohol. The skin edges are apposed to each other with gloved fingers or forceps and the vial inside the pen is then broken by squeezing the soft rubber part. Dermabond has to be used immediately after breaking the vial since the liquid starts to harden. The Dermabond Propen is then used to spread 2 thin layers of the adhesive liquid over the apposed skin edges, leaving 30 seconds time in between the 2 applications. The skin edges are then held together for 60 seconds till the liquid polymerizes. Complete polymerization takes up to 5 minutes. If a dry dressing is to be placed above the Dermabond layer, it should be done after this period to avoid the dressing sticking to the wound.

Label It Right With Adhesive   no comments

Labelling store products or any items for everyday use can make life very easy, but knowing which labels to use, when can make it even better. There are two basic types of self-adhesive labels namely permanent and removable. Each type of Adhesive is made using different types of glues depending on the conditions the label will have to endure, the amount of time it is required to stick and the environment or conditions of storage. These self-Adhesive labels are usually coated with an acrylic, rubber or water-based glue. The labels can be printed on by laser printers, inkjet printers, photocopiers or handwritten.

Laser printers and photocopiers are a hot process and it is recommended that A4 sheets of labels are only printed once for best results as the heat process evaporates the moisture in the adhesive each time it is passed through the printer. Water-based adhesives should only be used and stored in dry environments. Adhesive labels coated with rubber adhesives are preferred for their stickiness. However over time, they are prone to failure if exposed to the sun’s UV rays. If the labels are not likely to be exposed to sunlight, this type of adhesive works well. Acrylic-based adhesive labels can be easily moved around. This type of label adhesive is suitable for long-lasting products that need labels to withstand time and frequent handling. Depending on the surface to be labelled and the lifespan of the label, there are four types of adhesives commonly used.

These adhesives are: High tack (gummy to the touch) label adhesive is used for labels that have to stick permanently to rough surfaces, or shaped structures. If the label is not going to be removed then a permanent label adhesive should be used. The label and adhesive can only be removed by using a solvent. A peel-able label adhesive is suitable when a label is temporary and will need to be removed or replaced. The label will peel off and no adhesive residue will remain. These self-adhesive labels are also known as repositionable or removable labels. Freezer adhesives are used on freezer or refrigerator labels. The label adhesive will not crack or peel under the extreme cold and damp conditions. Static cling labels are usually plastic and can cling to smooth surfaces using a static charge only. They are easily repositioned or removed without leaving a residue. A4 Labels do not stock these labels.
