Kalama® VITROFLEX® B is a non-phthalate plasticizer based on innovative polymeric technology, specially designed for the “B” (catalyst) side of two-part polysulfide sealants. It has an excellent safety and regulatory profile relative to leading incumbent polysulfide plasticizers, such as phthalates and chlorinated paraffins.
Kalama VITROFLEX B results in excellent performance characteristics, bringing value to the critical end uses where polysulfide sealants are used. These include insulated glass seals, construction, transportation, and secondary containment. It imparts good rheology for suspension stability of dispersed solids, excellent elasticity and lap shear strength, and fast hardness development.
Emerald also offers complementary VITROFLEX polysulfide sealant plasticizers for the “A” (polymer) side: VITROFLEX A90 and VITROFLEX A99.
