LS-PHIPS Phenyltris(isopropenyloxy)silane
CAS NO.: 52301-18-5

Name: LS-PHIPS Phenyltris(isopropenyloxy)silane
Brand: Nanjing Silfluo New Material Co., Ltd.
Availability: InStock

Silfluo LS-PHIPS is a highly specialized, ultra-premium organosilane chemically identified as Phenyltriisopropenoxysilane. This unique molecule represents the absolute pinnacle of functional silane architecture by combining a highly stable phenyl group with three highly reactive, moisture-curing isopropenoxy (enoxy) groups.

This strategic combination delivers a dual-performance profile unmatched by standard crosslinkers. The isopropenoxy groups ensure a 100% neutral, MEKO-free cure that releases only benign acetone, making it exceptionally safe and non-corrosive. Simultaneously, the bulky phenyl ring injects extreme thermal stability, brilliant UV resistance, and a significantly elevated refractive index into the cured polymer network. LS-PHIPS is the absolute premier crosslinker and adhesion promoter for advanced, high-temperature RTV silicones, optical encapsulants, and heavy-duty composites operating in extreme environments.

Applications of LS-PHIPS Phenyltris(isopropenyloxy)silane

Silfluo LS-PHIPS is strictly engineered for high-performance, eco-friendly reactive polymer systems:

1. High-Temp De-Acetone RTV Silicones: Acts as the primary crosslinking agent in the manufacturing of specialty, extreme-temperature-resistant, MEKO-free silicone sealants used in automotive gaskets, aerospace components, and industrial ovens.

2. Optical & Electronic Encapsulants: The absolute material of choice for neutral-curing protective coatings and potting compounds used on sensitive printed circuit boards (PCBs) and high-brightness LED packaging where corrosion resistance and optical clarity are strictly mandated.

3. Advanced Composite Modifier: Utilized as a premium surface modifier and coupling agent for reinforcing mineral fillers in high-temperature thermosetting resins, significantly improving the composite's structural integrity under thermal stress.

Packing of LS-PHIPS Phenyltris(isopropenyloxy)silane

In 25kg pail, 200kg drum and 1000kg IBC.

Safety and Storage of LS-PHIPS Phenyltris(isopropenyloxy)silane

Keep in a cool, strictly dry, and well-ventilated environment. 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.
