As global photovoltaic (PV) installed capacity continues to climb, the weather resistance and adhesion strength of module encapsulation materials have become a focus of industry attention. Anhui Aiyota's vinyltrimethoxysilane, a key crosslinking agent for EVA (ethylene-vinyl acetate copolymer) films, is leading technological innovation in PV encapsulation materials.

This product's molecular structure contains active vinyl groups and hydrolyzable trimethoxysilane groups, which can undergo a crosslinking reaction with EVA molecular chains under peroxide initiation, forming a three-dimensional network structure. Actual test data shows that after adding an appropriate amount of vinyltrimethoxysilane, the gel content of the EVA film increases from 75% to over 85%, peel strength increases by 40%, and significantly enhances the adhesion between the solar cells and the glass and backsheet.

In damp heat aging tests, the EVA film modified with this product, after 1000 hours of treatment at 85℃/85%RH, maintained a light transmittance of over 95%, far exceeding industry standards. Its excellent UV resistance ensures that the power degradation of PV modules is controlled within a reasonable range during their 25-year outdoor lifespan.

Ayota's vinyltrimethoxysilane boasts a purity of ≥98% and is available in various packaging sizes ranging from 25kg to 200kg. It has already been supplied to several leading photovoltaic film manufacturers. Our technical team can provide crosslinking density optimization solutions based on customer formulations, helping to improve module power generation efficiency and reliability.
