Application
In Adhesives and Sealants: ChangFu® AC32 can be used as a coupling agent in adhesives and sealants. It enhances adhesion between organic polymers and inorganic materials (like glass, metals, or ceramics), improving the bonding strength and durability.
In Rubber and Plastics: ChangFu® AC32 can be used to enhance the bond between fillers (like silica or clay) and polymer matrices, improving the physical properties of composite materials, such as strength, thermal stability, and resistance to aging.
Glass and Metal Surfaces: ChangFu® AC32 can be employed to modify the surfaces of glass and metals, improving their interaction with other materials in coatings, paints, and laminates. It can also be used to create hydrophobic or hydrophilic surfaces, depending on the desired application.
Ceramic Coatings: ChangFu® AC32 can improve the adherence of ceramic coatings and is often used in the manufacturing of high-performance ceramics and composite materials.
Water-Repellent Coatings: ChangFu® AC32 can be used in formulating water-repellent coatings for construction materials (e.g., concrete, stone, and brick). The silane helps in repelling water and reducing the penetration of moisture, thus preventing degradation.
Anti-Corrosion Coatings: ChangFu® AC32 provides excellent adhesion between coatings and metal surfaces, offering protection against corrosion, particularly in automotive and industrial coatings.
Fabric Surface Modification: In the textile industry, ChangFu® AC32 can be used to modify fabric surfaces to improve water resistance and stain repellency.
Improvement of Dye Affinity: ChangFu® AC32 is also used in textile coatings to improve the affinity of dyes or pigments to fabrics.
In Fiberglass and Composite Materials: ChangFu® AC32 can be widely used in composite materials, particularly those that use glass fibers or other inorganic fillers. The silane enhances the bonding between the organic resin and the inorganic reinforcement, improving the mechanical properties of the composite.
In Carbon Nanotubes (CNTs): ChangFu® AC32 is also sometimes used to modify the surfaces of carbon nanotubes (CNTs) or other nanomaterials for enhanced dispersion in polymer matrices.
ChangFu® AC32 can be used in the production of silane-modified polymers (SMPs) that combine the properties of silane and polymer systems. These materials are used in high-performance applications such as sealants, adhesives, and coatings.
In electronics manufacturing, ChangFu® AC32 can be used for improving adhesion to substrates, enhancing the performance of electronic components and protective coatings on circuit boards.
