Description
About Shin-Etsu KS-609 Silane Coupling Agent
OVERVIEW:
Shin-Etsu KS-609 is an organofunctional silane coupling agent designed to improve adhesion between organic polymers and inorganic surfaces. It contains a vinyl functional group, making it especially suitable for use in cross-linking reactions and in enhancing compatibility between resins and substrates such as glass, metal, ceramics, and mineral fillers. KS-609 is commonly used to improve mechanical properties, water resistance, and durability in coatings, adhesives, sealants, and composite materials.
KEY FEATURES:
Adhesion Promotion
Enhances bonding strength between organic resins and inorganic surfaces, supporting improved structural performance and durability.
Vinyl Functional Group
Facilitates compatibility with various unsaturated resin systems such as polyethylene, polypropylene, and other thermoplastics and thermosetting resins.
Moisture Resistance
Forms stable siloxane bonds with inorganic substrates, improving moisture resistance and durability of the bonded interface.
Surface Modification
Used to modify filler surfaces, improving dispersion in polymer matrices and enhancing mechanical properties of the final material.
Versatile Application
Functions as a coupling agent, cross-linking agent, or surface treatment additive across diverse industrial sectors.
APPLICATIONS:
-
Polymer Cross-Linking – Used in the production of cross-linked polyethylene (PEX) and other cross-linked polymer systems to enhance mechanical and thermal properties.
-
Composite Materials – Improves bonding between resins and fillers or reinforcements, supporting enhanced mechanical strength and durability.
-
Adhesives and Sealants – Enhances adhesion to inorganic substrates, contributing to better bonding performance and moisture resistance.
-
Coatings – Used to improve adhesion and weather resistance of coatings on glass, metals, and ceramics.
-
Construction Materials – Applied in formulations to enhance the performance and longevity of building products.
PACKAGING:
Shin-Etsu KS-609 is typically supplied in sealed containers such as 1kg bottles, 15kg pails, or 200kg drums, depending on region and distributor availability.
INSTRUCTIONS FOR USE:
-
Surface Preparation: Clean substrate surfaces to remove oils, dust, and oxides for optimal bonding performance.
-
Application: Apply KS-609 as a surface treatment, primer, or formulation additive. For surface treatments, dilution with a suitable solvent may be required.
-
Curing: Allow sufficient time for hydrolysis and condensation reactions before further processing or assembly to achieve optimal adhesion.
