Features of LS-VTPS Vinyltris(tert-butylperoxy)silane
1. 100% MEKO-Free & Eco-Compliant: Hydrolyzes to release only neutral acetone gas, completely eliminating carcinogenic MEKO emissions. It ensures strict compliance with the most aggressive global indoor air quality and occupational health regulations.
2. Non-Corrosive Neutral Cure: The benign acetone byproduct causes absolutely no corrosion to sensitive metals (copper, brass, silver) or alkaline substrates (concrete, marble), making it perfectly suited for electronic potting and delicate construction joints.
3. Fast Skin-Over & Low Dirt Pick-up: Acetone evaporates exponentially faster than heavy oxime byproducts, allowing the sealant surface to skin over rapidly. This fast drying severely reduces airborne dirt pick-up on freshly applied joints.
4. Exceptional In-Can Stability: Exhibits profound stability when compounded in anhydrous systems. It functions as an aggressive hydroxyl scavenger, consuming trace moisture to definitively prevent premature gelation and extend cartridge shelf life.
Applications of LS-VTPS Vinyltris(tert-butylperoxy)silane
Silfluo LS-VIPS is strictly engineered for high-performance, eco-friendly reactive polymer systems:
1. Neutral Enoxy RTV Silicone Sealants: The primary crosslinking agent in the manufacturing of MEKO-free, de-acetone silicone sealants. It is frequently formulated synergistically with specialized tin-free organic catalysts (such as Silfluo LS-GCF) to produce ultra-premium, fast-curing architectural and sanitary elastomers.
2. Electronic Conformal Coatings & Potting: The absolute material of choice for moisture-curing encapsulants protecting sensitive PCBs and microprocessors, where zero-corrosion and high dielectric stability are strictly mandated.
3. Moisture Scavenger & End-Capper: Utilized as a highly efficient chemical desiccant during polymer compounding, and as a reactive chain-extender for synthesizing custom alkoxy/enoxy-terminated prepolymers.
Packing of LS-VTPS Vinyltris(tert-butylperoxy)silane
In 25kg pail, 200kg drum and 1000kg IBC.
Safety and Storage of LS-VTPS Vinyltris(tert-butylperoxy)silane
Keep in a cool, strictly dry, and well-ventilated environment.
Ensure all containers remain hermetically sealed under dry nitrogen until ready for use. The shelf life is a minimum of 12 months from the date of manufacture when stored at or below 25°C in tightly sealed, original unopened containers.
