Product Introduction
1. Product
Solid KH-550 Silane Coupling Agent, Solid Powder 3-Aminopropyltriethoxysilane, Replace Liquid KH550 for Coatings, Adhesives, Composite Materials
2. Brief Introduction
Different from conventional liquid KH-550 silane coupling agent, our Solid KH-550 is specially developed solid powder type amino silane. It keeps the same excellent coupling performance as liquid KH-550, solving the problems of liquid leakage, high VOC, inconvenient transportation and unstable formula mixing brought by traditional liquid silane. Widely used as core raw materials for coatings, glues and composite materials. We are a professional China Solid KH-550 manufacturer, providing factory direct sales, free samples and customized services for global industrial buyers.
3. Product Features
- Unique Solid Form: Exclusive solid powder design, perfectly meet customers’ demand for solid-state KH-550; no liquid leakage, safer for long-distance ocean transportation and warehouse storage
- Equivalent Performance to Liquid KH550: Retain complete amino functional group activity, same adhesion enhancement, water resistance and interfacial bonding effect as standard liquid KH-550
- Low VOC & Eco-friendly: No solvent volatilization, reduce workshop exhaust emission, fit global environmental protection production standards and dry-process production requirements
- Easy Formula Matching: Accurate weighing without dilution, compatible with all dry mixing production lines, no need to adjust original production equipment
- Stable Quality & Stable Supply: Independent R&D and mass production, strict batch inspection, long-term stable bulk supply for global downstream manufacturers

5. Main Applications
Solid KH-550 is a high-efficiency additive widely applied in three major industries, perfectly replacing liquid KH-550 for dry production processes:
✅ Coatings Industry
Used as adhesion promoter for powder coatings and industrial coatings; improve dispersion of inorganic fillers, enhance coating scratch resistance, waterproof performance and bonding force with metal substrates.
✅ Adhesives & Glues Industry
Key raw material for epoxy adhesive, polyurethane sealant and structural glue; improve bonding strength between glue layer and glass, metal, mineral fillers, suitable for solvent-free solid adhesive formulas.
✅ Composite Materials Industry
Surface treatment agent for glass fiber, calcium carbonate, silica and other fillers; improve interfacial combination of organic resin and inorganic materials, greatly boost mechanical strength and durability of finished composite products.

7. Frequently Asked Questions
Q1: What is the difference between solid KH-550 and regular liquid KH-550? A1: The core chemical performance is consistent. Liquid KH-550 is easy to leak and volatilize, only for wet mixing. Our solid KH-550 is powder form, suitable for all dry production lines, safer transportation and lower logistics risk.
Q2: Can solid KH-550 fully replace liquid KH-550 in existing formulas? A2: Yes. It can be directly replaced after simple dosage adjustment according to active content. Our technical team provides free formula adjustment guidance for all customers.
Q3: Can you provide free samples and complete export documents? A3: Free 1-5kg samples are available. We can provide SDS, COA, factory inspection report and other full sets of export documents to meet customs clearance requirements.
Q4: What is your MOQ? A4: 25kg for bulk order; small trial order is acceptable. We support customized particle size, package and product index for long-term cooperative clients.
