CRA® EM 460
CRA® EM 460 is an extremely efficient controlled release additive for adjusting the release force of silicone emulsion DEHESIVE® systems. It is used in combination with coating polymers such as DEHESIVE® EM 427 or DEHESIVE® EM 428 release coatings. The finished system is designed for pressure sensitive adhesive release applications and works on papers of varying porosity and on films. Cure is achieved using a vinyl addition chemistry mechanism.
特性
- can achieve very high release levels
- very stable release
- vinyl functional to crosslink into coating matrix
- fast curing
- contains α-olefin for higher efficiency
When used with other compliant WACKER products, such as DEHESIVE® coatings and appropriate crosslinkers, CRA® EM 460 is suitable for indirect food contact use as indicated in 21CFR 175.105, 175.300, 176.170 and 176.180, provided the product is appropriately cured under observance of the limits for platinum.
Note that FDA sanctioning of above components does not imply that the finished products manufactured from component combination are approved or considered safe by the FDA. Responsibility for compliance to the FDA regulations resides with the manufacturer of the finished product.
Batches of coating compound are prepared according to WACKER's 3-Component Emulsion Processing Guide for Release Coatings.
