# I N D U S T R I A L L A M I NA T I NGAdcote A3306/CR 857 September 2009 Page 2 of 2 Adcote A3306 can react or interact with other component s of laminations. Retained solvents, slip additives, antiblock agents, and contaminated solvents are some of the components that may cause property changes

of the film and/or adhesive.

High molecular weight polyesters that are used in solution adhesives like Adcote A3306 have tendency to

form a reversible structure in solution with time. This structuring is accelerated when the adhesive is exposed to temperatures below 50°F (10 ° C). The structuring is reversible if heat and shear is applied to the adhesive. We recommend placing the container of adhesive in a steam cabinet, allowing venting of the container and heating to 110-140°F (45-60 ° C). After the adhesive reaches the proper temperature,

mix the adhesive in the container for 1-3 hours under moderate shear. Use of a disperser or “Cowles” type blade will shorten the time needed.

Caution must be taken because of the flammability of the solvents used in the adhesive. Please

review MSDS for hazards associated with the adhesive.

Attempting to redisperse without heat may reduce the apparent viscosity, but not result in a homogeneous mix. Before using the adhesive, check, to make sure that all resin has returned to a true
solution and no gels remain
