Features Of Domestic D-13 Modified Methyltriacetoxysilane

  1. Enhanced hydrolytic stability compared to conventional triacetoxysilanes, reducing premature gelation during storage.

  2. Low volatility and reduced acetic acid emission during cure, improving workplace safety and indoor air quality.

  3. Excellent adhesion promotion to glass, aluminum, ceramics, and painted metal substrates without primer.

  4. Tailored reactivity profile for controlled crosslinking in one-component moisture-curing sealants and adhesives.

  5. Domestically manufactured under strict ISO 9001-certified process control, ensuring batch-to-batch consistency.

Typical Applications Of Domestic D-13 Modified Methyltriacetoxysilane

  1. Acetoxy-cure silicone sealants for construction joints and façade glazing.

  2. High-performance automotive RTV gasketing compounds.

  3. Electronics encapsulants requiring low-corrosion, non-halogenated crosslinkers.

  4. General-purpose industrial adhesives for bonding dissimilar substrates.

  5. Moisture-curable polyurethane and hybrid polymer formulations as a silane-based crosslinker booster.
