SR3602-35W Polyamide-Imide Resin Solution

Adhesion Promoter, Binder & Resin, Resins, Binders & Matrix Materials

In the original sealed container these products have a shelf life of 18 months when stored below 35°C.; Solution viscosity will increase over time. The rate of increase depends upon solvent, % solids and storage conditions.; The increase in viscosity does not affect polymer performance.; The viscosity can be adjusted with additional solvent and the material can be used with no performance loss.

SR3602-35W is supplied as a solution, care must be taken to enable the solvent to be removed slowly to avoid blistering of the film.; During curing, the temperature of the object should be increased slowly up to the final cure temperature to avoid blistering of the coating due to final release of solvent. Final cure temperature of >220°C is required.; The solvent system for SR3602-35W is hygroscopic, i.e., will slowly absorb moisture from the atmosphere.; 1-2% water content should not affect performance, but higher levels will lead to thickening of the product and difficulty in obtaining an acceptable impregnation.; For this reason the applicator tank should be closed.; It is advised not to mix used material with unused product for storage, although topping-off the process tank with fresh material is acceptable.

This product meets the definition of a polymer under REACH, and its components are registered as substances.. The material, or components, is either on the TSCA inventory list or is exempt from the requirement to be listed.
