CRA® EM 450
CRA® EM 450is 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, DEHESIVE® EM 428 or DEHESIVE® EM 492 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
- VOC free- does not contains α-olefin
When used with other compliant WACKER products, such as DEHESIVE® coatings and appropriate crosslinkers,CRA® EM 450 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
