VITROFLEX™ B

VITROFLEX B is a unique blend of dibenzoates specially tailored for the polysulfide market. This plasticizer is useful particularly in the B-side (catalyst) component of 2K polysulfide sealants. VITROFLEX B imparts good rheology for suspension stability of dispersed solids, elasticity, fast cure rates and hardness development.
