Features Of Domestic KH575 LT575 Gamma-Glycidoxypropyltrimethoxysilane

  1. High-purity domestic alternative to imported γ-glycidoxypropyltrimethoxysilane, meeting stringent quality consistency standards.

  2. Reactive epoxy and hydrolysable methoxy functional groups enable dual-cure capability with organic polymers and inorganic substrates.

  3. Excellent hydrolytic stability in formulated systems due to optimized synthesis process and controlled moisture content.

  4. Low volatility and favorable handling safety profile compared to lower-molecular-weight silane analogues.

  5. Enhanced compatibility with epoxy resins, acrylics, and unsaturated polyesters for improved interfacial adhesion.

Typical Applications Of Domestic KH575 LT575 Gamma-Glycidoxypropyltrimethoxysilane

  1. Adhesion promoter in epoxy-based structural adhesives and potting compounds.

  2. Surface modifier for silica fillers and glass fibers in high-performance composites.

  3. Functional additive in UV-curable coatings and inks to improve substrate wetting and crosslink density.

  4. Key coupling agent in rubber-to-metal bonding systems for automotive sealing applications.

  5. Stabilizer and dispersant aid in nano-silica reinforced silicone elastomers.
