KH-570 Coupling Agent, also known as 3-Methacryloxypropyltrimethoxysilane, is a silane coupling agent widely used to improve the adhesion between inorganic materials (such as glass, ceramics, and metals) and organic polymers. It plays a critical role in enhancing the mechanical strength, chemical resistance, and durability of composite materials.
Chemical Properties:
- Chemical Name: 3-Methacryloxypropyltrimethoxysilane
- Molecular Formula: C10H20O5Si
- Appearance: Clear, colorless to light yellow liquid
- Boiling Point: 255°C
- Density: 1.045 g/cm³
Main Applications:
-
Polymer Composites: KH-570 is commonly used to improve the bonding between glass fibers and resins in composite materials. This leads to better mechanical strength, durability, and overall performance.
-
Adhesives and Sealants: In adhesive and sealant formulations, KH-570 enhances adhesion to surfaces like glass, metals, and ceramics, improving the bonding strength and long-term reliability.
-
Coatings: Used in coating applications to improve adhesion, chemical resistance, and mechanical properties. It provides better durability to the final product, particularly in environments exposed to moisture and chemicals.
-
Rubber and Plastic Additives: KH-570 is also applied as a surface treatment in rubbers and plastics to enhance the dispersion of fillers and improve compatibility between the fillers and the polymer matrix.
Benefits:
- Improved Adhesion: Enhances bonding between organic and inorganic materials, resulting in stronger and more durable composites.
- Increased Mechanical Strength: Significantly improves the mechanical properties of composite materials, including tensile strength and impact resistance.
- Chemical Resistance: Adds chemical resistance to the final product, especially in environments exposed to moisture, acids, or other chemicals.
- Enhanced Processability: Makes it easier to work with composite materials by improving the dispersion of fillers.
