Kalama® VITROFLEX® non-phthalate, benzoate plasticizers have excellent safety and regulatory profiles for polysulfides. They enable formulators to eliminate plasticizers facing scrutiny and regulatory pressure, such as benzyl phthalate and chlorinated paraffins. Because Kalama VITROFLEX Plasticizers have been expressly designed for polysulfides, they also offer excellent performance characteristics, compatibility, and value in this application.
Kalama VITROFLEX A90 is tailored for the A-side of polysulfide sealants, where it provides exceptional permanence and low migration. These properties are critical to ensure low fogging in insulated glass, the largest application for polysulfide sealants.
Emerald offers solutions for the A-side (polymer) and B-side (catalyst) of 2-part polysulfide sealants. These products are manufactured in Europe, offering an excellent supply chain to serve EMEA customers. Additional solutions include Kalama VITROFLEX A99 and Kalama VITROFLEX B.
