LS-VI33 VTIPOS Vinyltriisopropoxysilane

Name: LS-VI33 VTIPOS Vinyltriisopropoxysilane
Brand: Nanjing Silfluo New Material Co., Ltd.
Availability: InStock

Silfluo LS-VI33 is a vinyl-functional organosilane, chemically identified as vinyltriisopropoxysilane.

The molecule contains a polymerizable vinyl group and three hydrolyzable isopropoxy groups.

The vinyl group participates in free-radical copolymerization during resin synthesis.

The bulky isopropoxy groups provide a significantly slower hydrolysis rate compared to methoxy or ethoxy equivalents.

This steric hindrance prevents premature hydrolysis in the liquid phase, enabling the formulation of shelf-stable, one-component (1K) waterborne systems.

Upon application and water evaporation, the silane hydrolyzes and crosslinks to form a durable siloxane network.

Performance equivalent to industry standards: Momentive CoatOSil 1706, Dow Z-6550.

Applications of LS-VI33 VTIPOS Vinyltriisopropoxysilane

1. Waterborne acrylic and vinyl latices: Used as a reactive comonomer during emulsion polymerization to introduce latent crosslinking sites while maintaining 1K in-can shelf stability.

2. Architectural paints: Used as a crosslinking additive in waterborne formulations to increase the scrub resistance and block resistance of the cured film.

3. Wood and industrial coatings: Used in waterborne finishes to enhance surface hardness and block resistance without compromising liquid storage stability.

4. Polymer modification: Used to graft vinyl functionality onto polymer backbones where delayed moisture-curing behavior is required.

Packing of LS-VI33 VTIPOS Vinyltriisopropoxysilane

In 5L, 10L, 25L pail, 200L drum and 1000L IBC.

Safety and Storage of LS-VI33 VTIPOS Vinyltriisopropoxysilane

Keep in a cool, strictly dry, and well-ventilated environment, aggressively avoiding direct sunlight, heat, sparks, and open flames. Classified and shipped as a hazardous substance (Class 3 Flammable Liquid due to its<51°C flash point). The shelf life is a minimum of 12 months from the date of manufacture when stored in tightly sealed, original unopened containers.
