Sridal Adhesive

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. 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. Restrain of water  (modified glue) Effective water absorption 35-40 g/m² 50-55 % 17-20 g/m² 12 % 15-18 g/m²    Reduction of Water Absorption 40 % This results in lesser warping of the case, better bonding and faster setting of the adhesive. Protein Glue keeps the water longer in the adhesive film which helps in improving the flatness of the case. Emulsion adhesive   creates an adhesive film by water absorption into the porous mat...

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 ...
