SEFLOR® CURATIVE VW-T
CURATIVE

Introduction

Masterbatch Seflor® CURATIVE VW-T is curative mixture suitable for ionic curable fluorinated elastomers (FKM) especially designed to prepare compounds according to VW 2.8.1 A/C/T requirements. It can be utilized as a curative for both di-polymer and ter-polymer types. It is recommended for ter-polymers since the FKM binder is terpolymer-based. It can be easily incorporated into the fluoroelastomer matrix thanks to the FKM binder.
