Features of LS-VI33 VTIPOS Vinyltriisopropoxysilane
1. Exceptional In-Can Stability: The massive steric hindrance of the isopropoxy groups dramatically slows down the hydrolysis rate in water. This ensures that water-borne formulations containing LS-VI33 maintain excellent viscosity stability and effectiveness even after a year of storage aging.
2. Formaldehyde-Free 1K Systems: Empowers formulators to create environmentally friendly, formaldehyde-free, true one-component (1K) crosslinking emulsions, eliminating the need for toxic external crosslinkers.
3. Reactive Vinyl Crosslinking: The active vinyl double bond readily copolymerizes with acrylic and vinyl monomers during emulsion polymerization, seamlessly grafting the silane functionality onto the polymer backbone.
4. Superior Film Performance: Upon final curing, it creates a densely crosslinked siloxane network that drastically enhances the hardness, scratch resistance, and wet adhesion of the resulting coating.
Applications of LS-VI33 VTIPOS Vinyltriisopropoxysilane
Silfluo LS-VI33 opens up new formulation possibilities for advanced water-borne (WB) coatings:
1. Premium Wood Coatings: Highly recommended for water-based coatings used on kitchen cabinets, industrial woodwork, and advanced furniture, providing superior block resistance and hardness.
2. Industrial Metal Coatings: Enhances the anti-corrosion properties and substrate adhesion of WB coatings for metal furniture, stationary appliances, machinery, and industrial equipment.
3. High-Performance Architectural Paints: Acts as a robust crosslinking additive in premium interior and exterior architectural coatings to significantly improve weatherability and scrub resistance.
4. Advanced Plastic Coatings: Improves the chemical resistance and structural integrity of water-borne finishes applied to diverse rigid plastic substrates.
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.
