CFS-475  3-(2,3-Epoxypropoxypropyl)methyldimethoxysilane(Z-6044 )

CAS No.: 65799-47-5

CFS-475 3-(2,3-Epoxypropoxypropyl)(Z-6044 )methyldimethoxysilane is an epoxy silane coupling agent containing both an epoxy functional group and hydrolyzable dimethoxy groups. It promotes the interfacial bonding between inorganic materials and organic polymers.

CFS-475 is particularly suitable for adhesives, sealants, coatings, and composite systems, where it functions as an adhesion promoter and crosslinking agent to improve adhesion, water resistance, and wet adhesion performance.

Key Functions

CFS-475 3-(2,3-Epoxypropoxypropyl)(Z-6044 )methyldimethoxysilane can be used as:

· Silane coupling agent

· Adhesion promoter

· Crosslinking agent

· Surface modifier

It promotes bonding between:

Inorganic materials (glass, metals, mineral fillers, etc.) ↔ Organic polymers

thereby improving:

· Adhesion

· Compatibility

· Water resistance

· Wet adhesion

· Mechanical properties of composites

Compared with trialkoxy epoxy silanes, the dialkoxy structure of CFS-475 3-(2,3-Epoxypropoxypropyl)(Z-6044 )contains one fewer hydrolyzable alkoxy group, providing better stability in waterborne systems and a lower tendency toward crosslinking.

Applications

CFS-475 3-(2,3-Epoxypropoxypropyl)methyldimethoxysilane (Z-6044 )is mainly used in:

· Automotive laminate adhesives

· Furniture laminate adhesives

· Flocking adhesives

· Waterborne acrylic sealants

· Waterborne adhesives and sealants

· Coatings

· Epoxy, polyurethane, and acrylic resin systems

· Glass fiber and mineral filler modification

· Filled PBT and nylon systems

· Rubber and composite materials

In waterborne adhesives and sealants, CFS-475 3-(2,3-Epoxypropoxypropyl)(Z-6044 ) improves wet adhesion and water resistance.

In filler and glass fiber systems, it improves the dispersion, compatibility, and bonding of fillers or fibers within the resin matrix.

Key Advantages

· Excellent adhesion-promoting performance

· Improved interfacial bonding between organic polymers and inorganic materials

· Enhanced wet adhesion

· Improved water resistance

· Good stability in waterborne systems

· Improved dispersion and bonding of fillers and glass fibers

· Suitable for various adhesive, sealant, coating, and composite systems
