Silane Coupling Agents
Silane coupling agents contain at least two different reactive groups within their molecules. One of these functional groups forms chemical bonds with inorganic materials, and the other forms chemical bonds with organic materials. This property enables silane coupling agents to function as intermediaries in bonding organic materials to inorganic materials, which normally tend not to bond with each other.
Higher-quality composite materials
Silane coupling agents improve dispersion during mixing of resins and fillers, and improve the mechanical strength, water and heat resistance, transparency, adhesion and other properties of the composite materials. Silane coupling agents are also highly effective in improving the chemical bonding of heat-cure resins and their compatibility with polymers.
Resin modification / Surface treatment
Reacting a resin with a silane coupling agent can improve its anchorage to inorganic materials, its low temperature humidity curing properties, and improve its weatherability and resistance to heat, acids and solvents. Silane coupling agents can also be used to treat the surface of inorganic materials to improve the materials' surface characteristics.
Quality, Storage and Handling
- The products should be kept in a cool, dark, and dry place.
- The coupling agents may deteriorate when in contact with water or moisture, producing byproducts such as hydrogen chloride from chlorosilanes and methanol or ethanol from methoxy silanes or ethoxysilanes, respectively. These products should be handled with special care when kept in the open air. After opening, they should be tightly sealed to limit exposure to water or moisture. It is recommended that dry nitrogen be used to replace the air in opened containers.
- Please contact our Sales Department for the SDS and read it carefully before using any of these products.
- These products should be handled with adequate ventilation to avoid contact with water or moisture. For example, when KA-1003 reacts with water or moisture in the air, it may generate corrosive hydrogen choloride gas, which is harmful to skin and membranes.
- To avoid contact with skin or membranes, it is recommended to wear gloves and goggles for protection. If contact occurs, flush immediately with large amounts of water.
- When eye contact occurs, flush the eyes immediately with large amounts of water and consult a doctor, if necessary. In the case of KA-1003 or aminosilanes, special and prompt care is required.
- If contact with clothes occurs, flush the exposed clothing with water and then wash the clothes immediately.
- After using silanes, wash hands very thoroughly before eating or drinking.
- If silane fluids are spilled, either flush the exposed area with large amounts of water or clean with rags or sand, which should be promptly disposed of by burning.
How to Use
Silane coupling agents have two different types of reactive functional groups.
