Abstract

SCA-E86M is a versatile epoxy functional organosilane possessing a reactive organic epoxide and hydrolyzable inorganic methoxysilyl groups. The dual nature of its reactivity allows SCA-E86M to bind chemically to both inorganic materials (e. g. glass, metals, fillers) and organic polymers (e. g. thermosets, thermoplastics, elastomers), thus functioning as an adhesion promoter, crosslinking agent and/or surface modifier.

 

Applications and Performance

1. Glass fiber/glass fabric composites: As a finish or a size ingredient.    

2. Foundry resins: As an additive to polyurethane resins.

3. Sealants and adhesives: As a primer or additive.  

4. Mineral filled composites: For pretreatment of fillers and pigments or as an additive to the polymer.

5. Paints and coatings: As an additive and as a primer for improving adhesion to the substrate, especially glass and metal.

6. Improved shelf life over aminosilanes in polyurethanes.

7. Important product effects that can be achieved through the use of SCA-E86M include: 

Improved mechanical properties, such as flexural strength, tensile strength, impact strength and modulus of elasticity.

Improved moisture and corrosion resistance.  

Improved electrical properties, for example dielectric constant, volume resistivity.
