Product Description
1,Polymer Matrix Single-terminal Silicone Graft Modification
Utilizing the unique terminal silicon-hydrogen bond (Si-H) of asymmetric PDMS, directional hydrosilylation reaction with unsaturated double bonds and active hydroxyl sites of polymers such as polyether, acrylic resin, epoxy resin and polyurethane is carried out under platinum catalysis to realize controllable single-terminal grafting of PDMS segments. It effectively avoids system curing, thickening and gelation defects caused by bidirectional cross-linking of double-terminal hydrogen-containing silicone oil. The modified polymer matrix is endowed with excellent hydrophobicity, oleophobicity, low surface tension and weather resistance, while maintaining the original mechanical and light transmittance properties of the matrix.
2,Synthesis of Controlled Block/Comb-type Silicone Copolymers
With monofunctional and asymmetric molecular topological structure, it can be used as a terminal capping modification unit for step polymerization with various organic and inorganic monomers to accurately synthesize well-structured block and comb-type silicone copolymers. The inert terminal group can terminate the polymerization reaction and eliminate intermolecular cross-linking and entanglement. It solves the industrial problems of traditional difunctional silicone oil, such as easy formation of three-dimensional network structure, broad molecular weight distribution and poor product stability, and can prepare functional copolymers with uniform structure and stable performance.
3,Preparation of Low-surface-energy Functional Coatings and High-end Additives
The asymmetric PDMS segments possess excellent low surface energy, high and low temperature resistance, oxidation resistance and low volatility. After single-terminal graft modification, it can be used to prepare high-performance coating leveling agents, defoamers, anti-graffiti additives and release agents. The modified additives can be directionally arranged on the coating surface, and the silicone segments enrich outward to form a dense protective film with low surface energy, which significantly improves the lubricity, stain resistance, weather resistance and flatness of the coating without causing shrinkage, loss of gloss and excessive cross-linking.
4,Precise Molecular Functional Modification and Research-grade Intermediate Application
As a single-terminal reactive silicone intermediate with definite structure and single functionality, it is applied to the precise surface functional modification of nanomaterials, polymer microspheres, interfacial thin films and biomedical materials. Relying on its controllable single reaction site, it realizes molecular-level accurate graft modification and precisely regulates the surface interfacial properties, hydrophobic properties and mechanical properties of materials. It has no side reactions and cross-linking impurities, and its purity and controllability meet the preparation standards of cutting-edge scientific research and high-end customized materials in materials science, fine chemical industry and biomedicine.
