Siwin-WP022 is a widespread-used crosslinking agent, which is usually applied for the production of RTV silicon rubber. It is usually applied in paint to improve the weather-resistance, scrab- resistance, water-resistance and corrosion-resistance. It can be used as the surface-treatment agent of mineral material and glass.It can be applied into the production of water-resistant material.

Application
Waterproofing and Protective Materials
As a solvent-based neutral waterproofing agent, it is widely used in construction, wood preservation, and cultural relic protection. By hydrolyzing to form siloxane films, it prevents water penetration and enhances weathering resistance, particularly for insulation materials and high-end architectural waterproofing.
Applied as anti-fouling coatings on concrete, stone, and other substrates, combining breathability and weather resistance to extend building lifespans.
Rubber and Resin Industries
Serves as a crosslinker for room-temperature vulcanized (RTV) silicone rubber, significantly improving tensile strength, elongation, and chemical resistance, outperforming traditional crosslinkers (e.g., tetraethyl orthosilicate).
Used in silicone resin production, endowing materials with exceptional heat resistance (>300°C), weather resistance, and chemical stability for applications in electronic encapsulation and automotive coatings.
Composites and Surface Treatment
Modifies glass fibers and inorganic fillers (e.g., silica, mineral powders) via silanol reactions to enhance compatibility with resin matrices, boosting mechanical strength and moisture resistance in composites.
Acts as a glass surface treatment agent, improving hydrophobicity and corrosion resistance for optical devices and architectural glass.
Specialized Industrial Additives
Functions as a release agent and defoamer in rubber and plastic molding processes, improving production efficiency and reducing surface defects.
In electronics, used for carbon fiber surface coatings and nanocomposite synthesis to optimize conductivity and mechanical properties.
Other Functional Applications
As a pressure-sensitive adhesive release agent, it enables efficient residue-free peeling when combined with methyl RTV silicone rubber.
In cultural relic conservation, provides weathering-resistant reinforcement for stone and wood materials while preserving original appearance
