CRA® EM 460 is a highly efficient controlled-release additive specifically developed for adjusting the release force of silicone emulsion-based DEHESIVE® systems. It is used in conjunction with coating polymers like DEHESIVE® EM 427 or DEHESIVE® EM 428 to create release coatings. The resulting system is designed for pressure-sensitive adhesive release applications and is compatible with papers of different porosities and films. The cure is achieved through a vinyl addition chemistry mechanism.
