Moisture Scavengers for Adhesives and Sealants

Dynasylan® VTEO by Evonik is a vinyltriethoxysilane grade. It functions as a surface modification, an adhesion promoter, and/or a crosslinking agent. It has the ability to absorb moisture. It offers enhanced mechanical and electrical qualities, enhanced wet adhesion strength, enhanced wet scrub resistance, and enhanced corrosion or scratch resistance. Dynasylan® VTEO is listed on EINECS/ELINCS, AICS, DSL/NDSL, PICCS, TSCA, IECSC, ENCS, REACH and ECL. It has a shelf life of at least 12 months.

Dynasylan® VTMO by Evonik is a vinyltrimethoxysilane-based moisture scavenger, surface modifier, crosslinking agent, and adhesion promoter. It improves abrasion resistance, chemical resistance, tear and fracture resistance, and memory effect.

• It reduces bubbles formation from the reaction of NCO groups with moisture.
• It provides low viscosity, enhanced wet adhesion strength, enhanced corrosion resistance, and resistance to wet scrub.
• Dynasylan® VTMO is listed with EINECS/ELINCS, AICS, DSL/NDSL, PICCS, TSCA, IECS, ENCS, ECL and REACH.
• It has a minimum shelf life of 12 months.

PTSI (p-toluenesulfonyl Isocyanate) by Foru Chemtech is a moisture scavenger. It is a colorless, transparent liquid with low viscosity and a single functional isocyanate group. It reacts readily with water, helping to remove moisture in polyurethane (PU) formulations. PTSI (p-toluenesulfonyl Isocyanate) is used in PU systems to eliminate moisture in solvents, fillers, pigments and adhesives.
