DEHESIVE® EM 428
DEHESIVE® EM 428 is the base polymer to a three component aqueous emulsion system. It is used in combination with WACKER® CROSSLINKER V 15 and WACKER® CATALYST EM 459. The product is designed for pressure sensitive adhesive release applications and works on papers of varying porosity and films. Cure is achieved using a vinyl addition chemistry mechanism.
- Good anchorage on a wide variety of paper substrates
- Formulation flexibility allows for variation of hydrogen:vinyl (SiH:SiVi) mole ratio and platinum catalyst content
- Compatibility with various thickening agents allows for absorbent substrate processing
- Adjustable release level when used in conjunction with CRA® EM 460
Batches of coating compound are prepared according to WACKER's 3-Component Emulsion Processing Guide for Release Coatings.
