It can improve the electrical properties and mechanical strength of inorganic filler-filled EPDM, cross-linked polyethylene and other polymers or resins. Especially in the wet state its performance is more significant. Silane can be used to pretreat clay and silicon-containing inorganic fillers, or be added by blending.
This product can improve the mechanical strength of composite materials such as cross-linked, inorganic filler-filled or reinforced polyester in dry and wet states. Silane This product reduces the hygroscopicity of the cross-linked polyester molding compound, thereby improving the electrical properties and mechanical strength in the wet state.
In the application of glass fiber, silane can improve the adhesion of fiber monofilament and polyester resin, and improve the performance of composite materials in wet state. Silane This product is added to the sizing agent, and the sizing agent is coated on the fiber monofilament during drawing.
This product can improve the adhesion of printing inks, glues and coatings on surfaces such as glass, ceramics or metals, and has the advantage of lower cost than ceramic melting processes. As part of the label adhesive, silane can enhance the adhesion of labels on the surface. The dosage of silane is 1% in ink or adhesive.
This product can improve the adhesion of silicone rubber on polyester or glass surfaces. This adhesion is especially important in high temperature applications (such as shipping tape) and hot air vents (such as exhaust hoses).
It can be used to copolymerize silane with monomers in emulsion or coating polymer, or use silane to graft with active energy group or unsaturated polymer to produce room temperature cross-linked water-based and solvent-based coatings such as acrylic latex coating.
This product is a coupling agent for filled rubber compounds, and can also improve the viscosity and durability of emulsions or coatings. It can hydrophobize the filler, improve the compatibility between the filler and the polymer, make the dispersibility better, and reduce the melt viscosity. It can improve the adhesion between the fiber monofilament and the resin, and the performance of the composite material in the wet state. It can provide cross-linking points for organic polymers and can be used as polymer material modifiers, EPDM modifiers, and cross-linking agents for silane cross-linked cable materials.

The standard packaging is 200Kg iron drum and 1000Kg IBC container.
Store in the original unopened container at 25℃ or below. The shelf life of this product is half a year from the date of production. Expired products can only be used after passing the test.
