Highly reactive silane offering rapid room-temperature crosslinking with moisture.
Excellent adhesion promotion to glass, metals, and mineral substrates without primer.
Low volatility and favorable handling characteristics compared to chlorosilanes.
Enables formation of flexible, durable silicone networks in one-component systems.
Compatible with common organic polymers including acrylics, polyurethanes, and alkyds.
Moisture-curing sealants for construction and automotive glazing.
Adhesives requiring strong substrate bonding and environmental resistance.
Coating additives to enhance scratch resistance and substrate wetting.
Filler treatment for silica and calcium carbonate in silicone-modified composites.
Hybrid polymer formulations (e.g., MS polymers) demanding high reactivity and low odor.
