ANIMAL GLUE PROBLEMS-TEMPERATURE Running our animal glue at too low of a temperature can cause a few problems: Stringing, Poor machining, Adhesive that's too thick, Adhesive that sets too quickly. If you are having these problems, try raising the temperature. We recommend a range of 140-150 degrees Fahrenheit for our animal glue. Low humidity can also cause glue to set too quickly- if raising the temperature doesn't fix the problem, try to dehumidify the area surrounding the animal glue and its application as much as possible. Also, the glue could be over-diluted; add some fresh adhesive to remedy. Lastly, try reducing the application rate. If none of these tips work for you and you're still having trouble, contact your sales representative-it may be time to try a different type of SRIDAL animal glue. On the other hand, running animal glue at too high of a temperature can cause opposite problems, such as adhesive that sets too slowly. Try lowering the temperature for ...

When a customer contacts SRIDAL for help with animal glue problem, we are happy to help and find an adhesive solution for their application. Below is an idea of the steps our customers and SRIDAL go through to solve these issues. ADHESIVE TROUBLESHOOTING First, we recommend that the customer troubleshoots at their facility to make sure all the parameters for the adhesive application are set correctly. They should check for issues with working temperature, humidity, cardboard conditions. Click our blog about animal glue troubleshooting . Know the kind of glue you are using and realize its tendencies. Hot melt adhesives and animal glues are very different from one another. Animal glue is all-natural and as such, it will react to different environmental conditions. We can recommend changes in dilution and temperature depending on the season and even offer winter and summer formulas of some of our animal...

The features of the Jelly Glue : High initial tack, non-warp character, fast drying speed, clean running with less string, high flexibility dried film, with excellent performance on automatic machine. Its advantage is to increase the hardness of the paper board; it runs by mechanical production with heating device. The applications of Jelly Glue are for binder, file, calendar, photo album, diary, hardcover book, board games, rigid box and cases (for gift, jewelry, shoe, cosmetics, watch and cellphone).

Animal Glue or Protein Glue , an adhesive commonly used for Case making is also called Gelatin Glue, Jelly glue or  Glutin . It is made of connective tissue and bones and hides of animals. It is manufactured using animal protein which is obtained by breaking, milling the bones and cooking or boiling the raw-materials. The major characteristics of Protein glue is that it has strong wet tack, strong cohesion power and is hygroscopic in nature. If a comparison is made between Protein glue and water based emulsions for case making, it would be clearly understood that Protein glue is the most suited for the application. An illustration below will explain the theory, further  Average glue application (coating weight) for laminating (example): Emulsion adhesives:   Wet Dry substance  Water absorption  50-70 g/m² 50-55 % 25-35 g/m² Protein Glue:   Wet Dry substance  Water absorption  + add.

Jelly Glue These are water-based adhesives whose essential ingredient is collagen, a natural polymer. Collagen proteins, derived from natural sources, are mixed with other safe ingredients including sugar, Epsom salts, glycerin and water.   Generally JELLY GLUE bonds surfaces which are water sensitive, such as paper, board, cloth, foam, backed vinyl fabrics and the like. These products are characterised by strong initial tack properties, along with the proper set time, clean machining, and pleasant odor and provide long adhesive mileage.   When using our jelly glue – it should be melted, preferably in a temperature –controlled, jacketed gluepot, or pre-melt tank to 60-65oC. It may be used undiluted or diluted to your preferred viscosity with clean hot water. Hot jelly glue is applied to one of the surfaces to be bonded, and the surfaces are joined and compressed. The adhesive surface cools and the bond forms. It can be applied by a wide range of highly sophisticat...
