Changfu Chemical SUA33 - A high-quality coupling agent for achieving strong bonding between inorganic and organic materials.

In the field of composite materials, the efficient combination of inorganic materials and organic materials is the key to improving product performance, and it is also a long-standing technical difficulty. ChangFu^® SUA33 [(3-triethoxysilyl) propyl succinic anhydride; CAS: 93642-68-3] launched by Changfu Chemical is a silane coupling agent containing anhydride functional groups. Its molecular structure has both the tackifying properties of silane and the high reactivity of anhydride. It can effectively graft organic resins containing active hydrogen, significantly enhance the interfacial bonding force between inorganic materials and organic polymers, and thus comprehensively improve the mechanical properties, durability and reliability of the final product.

Product features:

l  Excellent carboxylic acid coupling agent and crosslinking agent.

l  It can react with amino, epoxy, hydroxyl and other groups, and is used for polymer modification.

l  Provides enhanced compatibility and improved bonding performance in various composite materials.

Typical Applications:

1. Adhesion Promoters: Enhance the adhesion of adhesives and sealants (such as silicone adhesives, epoxy adhesives) to substrates like glass and metal.

²  Electronic packaging adhesives (epoxy resins, organic silicones)

²  Construction and industrial sealants (silicone adhesives, polyurethane adhesives)

²  High-performance coatings and inks

2. Composite Materials: Used in glass fiber and mineral-filled plastic composites, significantly improving their mechanical strength and durability.

²  Unsaturated polyester glass fiber reinforced plastics (used in ships, water tanks, automotive parts)

²  Epoxy resin composites (used in circuit boards, aerospace components)

²  Mineral-filled thermoplastics (such as PP, PA filled with calcium carbonate, talc)

3. Surface Treatment Agents: Used as surface treatment agents for inorganic materials like glass, metals, and silica, and can better compatibility and bond with organic resins.

²  Surface modification of nano-silica

²  Anti-corrosion pretreatment of metal surfaces

²  Functionalization of glass surfaces

ChangFu^® SUA33 [(3-triethoxysilyl) propyl succinic anhydride; CAS: 93642-68-3] precisely optimizes the organic-inorganic interface structure, significantly enhancing the strength and durability of composite materials. Make adhesion stronger and materials more excellent!
