Name: Domestic D-16 Propyltriacetoxysilane
Brand: Guangzhou Eric Wei Chemical Co., Ltd.

Features Of Domestic D-16 Propyltriacetoxysilane

Highly reactive triacetoxysilane structure enabling rapid room-temperature condensation with hydroxyl-bearing substrates.
Propyl functional group provides excellent hydrophobicity and compatibility with organic polymers and resins.
Low volatility and reduced acetic acid odor compared to conventional acetoxysilanes, improving workplace handling safety.
Enhanced shelf stability under sealed, anhydrous storage conditions (24 months at ≤25 °C).
Effective adhesion promoter for glass, metals, ceramics, and mineral-filled composites without pre-treatment.

Typical Applications Of Domestic D-16 Propyltriacetoxysilane

Single-component moisture-curing sealants and adhesives for construction and automotive assembly.
Primer additive in silicone-based RTV formulations to improve interfacial adhesion to challenging substrates.
Surface modifier for silica fillers and calcium carbonate in rubber and thermoplastic composites.
Coupling agent in UV-stabilized acrylic sealants requiring long-term weather resistance.
Key ingredient in high-performance stone and concrete bonding agents for façade systems.
