Product Introduction
KH-550 Silane Coupling Agent
Nanjing Chem Co.,Ltd is one of the leading KH-550 suppliers and also a professional Silane coupling agent manufacturer in China.
KH-550 is an important silane coupling agent and widely used in industries like adhesive, paint, etc.
KH-550, also known as 3-Aminopropyltriethoxysilane, is one of the most widely used amino silane coupling agents in the global chemical industry. It features dual reactive functional groups: hydrolyzable ethoxy groups that bond with inorganic substrates, and active amino groups that crosslink with organic polymers.
This universal silane coupling agent serves as a core chemical raw material for coatings, adhesives and composite materials. It effectively improves interfacial adhesion between organic resins and inorganic fillers, enhances product mechanical strength, water resistance and anti-aging performance, and solves common bonding defects in industrial production. We supply standard industrial-grade KH-550 with stable quality, consistent batch indicators and competitive factory direct price for global B2B industrial buyers.
1. Core Product Advantages
- Excellent Coupling Performance: Perfectly connect inorganic materials (glass fiber, silica, calcium carbonate, metal powder) and organic resins, significantly improving interface bonding force
- Wide Compatibility: Suitable for water-based and solvent-based formulas, compatible with most epoxy, polyurethane and acrylic resin systems
- Low Impurity & Stable Performance: Strict distillation and purification process, low volatile content, no yellowing during long-term storage
- Cost-Effective Industrial Solution: Versatile for multiple industries, reduces formula failure rate and overall production cost for downstream manufacturers

3. Main Industrial Applications
As a universal silane coupling agent, KH-550 is widely adopted in three core downstream industries:
3.1 Coatings Industry
Used as adhesion promoter and filler modifier for industrial coatings, powder coatings and anti-corrosion coatings. It improves pigment and filler dispersion, enhances coating adhesion on metal, glass and plastic surfaces, and boosts waterproof, scratch-resistant and anti-corrosion performance of finished coatings.
3.2 Adhesives & Sealants Industry
Key additive for epoxy glue, polyurethane adhesives, structural adhesives and sealants. KH-550 improves bonding strength between adhesive layers and inorganic substrates, reduces glue shrinkage, and extends the service life of adhesive products.
3.3 Composite Materials Industry
Common surface treatment agent for glass fiber, mineral fillers and plastic composites. It optimizes the interface between fiber and resin matrix, improves the tensile strength, bending strength and durability of FRP, plastic reinforced composites and other finished parts.

5. Frequently Asked Questions
Q1: What is the function of KH-550 silane coupling agent?
A1: KH-550 acts as a bridge connecting inorganic substances and organic resins. It can significantly improve interface adhesion, mechanical strength, water resistance and weather resistance of coatings, adhesives and composite materials.
Q2: What is the difference between KH-550 and other common silane coupling agents?
A2: KH-550 is amino-functional silane with higher activity, better water solubility and wider formula compatibility compared to epoxy silane or vinyl silane. It is more cost-effective for general coating, glue and composite production scenarios.
Q3: Do you provide free samples and technical support?
A3: Yes. We offer free small trial samples for customer testing. Our professional technical team provides free formula guidance, usage dosage suggestion and after-sales technical support for all buyers.
