Features Of DOW XIAMETER OFS-6040 Silane

  1. Highly reactive vinyl-functional silane for robust covalent bonding to inorganic substrates.

  2. Enables excellent adhesion promotion between organic polymers and glass, metals, or mineral fillers.

  3. Hydrolytically stable formulation with optimized shelf life under recommended storage conditions.

  4. Low volatility and low odor profile, supporting safer handling in industrial environments.

  5. Compatible with common solvents (e.g., alcohols, aromatics) and widely used in aqueous and non-aqueous systems.

Typical Applications Of DOW XIAMETER OFS-6040 Silane

  1. Adhesion promoter in silicone sealants and RTV elastomers for architectural glazing.

  2. Surface modifier for glass fiber reinforcements in thermoset composites (e.g., polyester, epoxy).

  3. Functional additive in UV-curable coatings and inks for enhanced substrate anchoring.

  4. Performance enhancer in mineral-filled polyolefin compounds to improve filler dispersion and interfacial strength.

  5. Key ingredient in automotive under-hood sealants requiring thermal and humidity resistance.
