LS-B6224 Vinylbenzylaminofunctionaltrimethoxysilane

Silfluo LS-B6224 is a low-chloride, partially hydrolyzed vinylbenzyl amino functional silane supplied as an active solution in methanol.

The molecule is based on a vinylbenzyl diamino silane structure and contains vinylbenzyl functionality, diamino groups, and partially hydrolyzed silanol groups.

The vinylbenzyl group participates in free-radical curing systems.

The silanol groups react with hydroxylated inorganic surfaces including glass fiber, silica, and silicate minerals.

Partial hydrolysis is performed during manufacturing, reducing the need for in-house hydrolysis before use in aqueous sizing or finishing baths.

Used in glass fiber treatment, fiberglass fabric finishing, and electronic laminate applications where chloride control and interface reliability are required.

Benchmark chemistry: Dow Z-6224 / XIAMETER OFS-6224 type low-chloride, partially hydrolyzed vinylbenzyl amino silane.

Applications of LS-B6032 Benzylsilane 3-(N-Styrylmethyl-2-aminoethylamino)-propyltrimethoxysilane


1. PCB and CCL glass fiber treatment

Used for glass fabric and fiberglass surface treatment in epoxy-based and selected thermoset laminate systems. Verify ionic residue, wet adhesion, and laminate reliability in the target system.

2. Silica and mineral filler modification

Used for silica, silicate, and mineral filler treatment in filled resin systems, adhesives, coatings, and composites. Verify compatibility, dispersion, and mechanical properties in the target compound.

3. Composite reinforcement

Used with unsaturated polyester, vinyl ester, acrylic, and epoxy resin systems to support filler-resin and glass-resin interfacial adhesion. Verify wet mechanical properties and aging behavior in the target composite.

4. Primers and surface modifiers

Used in alcohol-based or water-dilutable primer systems for glass, ceramic, mineral, and selected metal surfaces. Verify adhesion and film properties in the target formulation.

5. Electronic encapsulants and adhesives

Used as adhesion promoter in potting compounds, encapsulants, and structural adhesives. Verify compatibility and ionic impurity levels in the target system before use.
