1、After glass fiber treated with silane coupling agent is made into products, one end of the silane coupling agent forms a solid chemical bond with the surface of the glass fiber, and the other end of forms a solid chemical bond with the resin, so the bending strength, water resistance and heat deflection temperature of the composite material are significantly improved, its strength is even higher than the pure resin.
2、Hengda Chemical is the earliest manufacturer of silane coupling agent developed for glass fiber industry in China, and rich experienced in its production and application.

1. In artificial marble, silane coupling agent improves the bonding strength between resin and inorganic material.
2. Improving water resistance of artificial marble through the hydrophobicity of organic silicon.

The silane coupling agent can chemically improve the combination of the organic resin and fillers/pigments, improve the crosslinking density and cohesive strength of the resin through the hydrolysis of alkoxy group and the reaction of the organic group with the resin.
It can also improve the adhesion strength between the resin and the substrate, can increase the water resistance of the system.
HENGDA Chemical is the first company in China to jointly develop polyether MS adhesives with adhesive manufacturers. Subsequently, we jointly developed silicone adhesive (structural adhesive and sealant) and silane-terminated polyurethane adhesive (adhesive and sealant) with adhesive manufacturers.

HENGDA Chemical provides high quality organosilane coupling agent for synthetic silicone fluids/oil, such as amino silane, diamino silane, vinyl silane, mercaptosilane, etc..

The resin modified by silane coupling agents have the comprehensive properties of the original resin and the silicone resin.
Modification methods include physical blending and chemical reaction.
1. Physical blending: Add the silane coupling agent directly to the resin and mix evenly.
2. Chemical reaction: Including co-condensation, co-polymerization, and hydrosilylation.
The resin modified by the silane coupling agent has great heat resistance, weather resistance, corrosion resistance, electrical insulation and excellent physical and mechanical properties.
Hengda Chemical has vast experience on the use of silane coupling agent modified phenolic resin and modified furan resin in the foundry industry.

Silane coupling agents can enhance the bonding force between silica and rubber, thereby increasing strength and improving vulcanization performance.

Silica sol and silane coupling agent are the main raw materials for preparing slurry for precision casting. The coating film made with this slurry is dense and hard, with excellent surface finish, water resistance and heat resistance.

1. The main function of silane coupling agent in coatings and inks is to improve the adhesion, water resistance, weather resistance, and abrasion resistance of the coating film and the substrate, improve the compatibility/dispersibility of the resin and the extender pigment, and improve the cross-linking component system of the matrix resin, and increases the surface hardness of the coating film.
2. In metal surface treatment, silane coupling agent can partially replace electrophoretic paint or electroplating, form a temporary protective layer on the metal surface, and improve the adhesion between the substrate and the next coating.

The photovoltaic industry is another highlight application of Hengda's silane coupling agent. Through in-depth cooperation with photovoltaic panel manufacturers, silane coupling agents for photovoltaic panels have been developed, which can significantly improve the adhesion strength and transparency between EVA, POM and other materials with glass panels.

Amino silane coupling agent and mercapto silane coupling agent are important raw materials synthesizing textile auxiliaries. HENGDA Chemical provides high purity silane coupling agents for textile auxiliaries.

The surface treatment of pigments and fillers by silane coupling agents can increase the affinity of pigments and fillers to resins, and avoid or reduce the decline in physical properties such as mechanical properties and electrical properties of resins caused by the addition of pigments and fillers It can also reduce the viscosity of the resin system, and increase the resin system. Excellent water resistance and chemical resistance.

Silane coupling agents are used to modify the pigments, fillers and glass fiber reinforced materials in plastics or composite materials.
It can enhance the water resistance and chemical resistance of plastics and composite materials and aslo improve bending strength, electrical properties and heat resistance of the materials.

1. Improve the adhesion and water resistance of building protective materials and building substrates through the hydrolysis of silane coupling agents and the chemical reaction with building substrates.
2. Through the reaction between the organic functional groups of the silane coupling agent and the building protection resin, the cohesive strength of the building protection material is improved, and the hydrophobicity and UV resistance are enhanced.

In the production of thin-shell casting models or cores, adding silane coupling agents to the mixture of resin and sand can make models and cores with better strength, which are resistant to operational damage and degradation in adverse environments. Models and models The breathability of the core is also significantly improved.

1. The silane coupling agent significantly improves the electrical insulation and crosslinking density of the product.
2. Silane coupling agent can improve the binding force between inorganic materials and organic resins.
3. The organic functional group of the silane coupling agent participates in the reaction, which significantly increases the crosslinking density of the resin, improves the built-in strength of the resin, and improves water resistance and dielectric constant in the meantime.

Polyphenylmethyldimethylsiloxane is widly used in self-lubricating liquid silicone rubber, it can improves the lubricating properties of the silicone rubber, enhances its mold release properties, can also helps reduce surface defects such as sticking, tearing, or roughness, resulting in products with a smoother and more aesthetically pleasing finish.
It exhibits good thermal stability, maintaining its lubricating and release properties over a wide range of temperatures and this is particularly important in applications where silicone rubber parts are exposed to fluctuating or extreme temperature conditions.
Overall, it plays a key role in enhancing the performance and quality of self-lubricating liquid silicone rubber by providing superior lubrication, mold release, surface quality, temperature stability, chemical inertness, and durability.

Dimethyl Silicone Fluid as a defoamer, is widely used in chemical, petroleum, coatings, plastics, textile and other industrial fields, like food and beverage industry and pharmaceutical fields. It has the advantages of high efficiency, environmental friendliness and economy, with 4 characteristics below:
-Reducing surface tension.
-High stability.
-High temperature resistance.
-Chemical resistance.

Silicone Fluid with good compatibility with alcohol and other cosmetic ingredients, is used as additive for a wide variety of cosmetic and personal care products. They are stable against heat and ultraviolent light, and have other superior properties such as water repellency, nonadhesiveness and good elongation. Widely used into foundation, make-up, skin care products, hair care products, sunscreen etc.

Highly hydrogen-containing silicone oil is mainly used as a waterproofing agent for waterproof gypsum boards, gypsum waterproof boards, gypsum blocks and other products. The water absorption rate is less than 10%, which meets the standards. Under the action of metal salt catalyst, it can be cross-linked to form a film at low temperature, forming a waterproof film on the surface, which is moisture-proof, mildew-proof, rust-proof and breathable.
