XJY-8205 MQ resin can be applied to:

1. Reinforcing material: Condensation-type liquid silicone rubber(LSR).

2. For Release agent: For urethane rubber such as shoe soles.

3. For Silicone Defoamer: It can be used to prepare high-temperature and strong alkali-resistant silicone defoamer. The silicone defoamer also has the advantages of non-toxicity and environmental protection. By adding high-viscosity hydroxy silicone oil and silicone MQ resin to synthesize a network polymer with a high degree of branching, so as to improve the high-temperature resistance and strong alkali resistance of the defoamer.

4. For polishes, excellent additive to enhance the water-repellent properties of automotive and domestic care systems.

5. Silicone Pressure Sensitive Adhesive(SPSA):

Because the solvent type contains a large amount of volatile organic compounds, solvent volatilization is easy to cause serious pollution to the environment during curing. Nowadays, environmental protection has been paid more and more attention. The silicone pressure-sensitive adhesive industry is taking environmental protection and low-cost products as the development mainstream, and taking biodegradable, radiation curing and other new products as the research direction. Silicone MQ resin mainly plays the role of tackifying and reinforcing. The silicone hydroxyl group or vinyl group in MQ resin can condense with the hydroxyl group of silicone rubber or with silicone rubber through hydrogen-containing siloxane under the action of catalyst, so as to prepare silicone pressure-sensitive adhesive.

6. Film-forming in personal care and cosmetic

7. Other applications:

①The silicone MQ resin containing SiH groups or aralkyl groups is used as a crosslinking agent. Under the action of a platinum catalyst, a phenyl silicone resin-containing packaging material is synthesized with a silicone resin containing vinyl and high phenyl groups. The material is compatible and compatible. With good transparency, high hardness, and high refractive index, it can be used for LED packaging and lens production.

②With MQ hydrogen-containing silicone oil and silyl enoate, under the catalysis of Pt, the hydrosilylation reaction occurs to obtain MQ resin-modified carboxyl silicone oil. It can be used in combination with amino silicone oil emulsion to give fabrics a better soft, smooth, and plump feel.


Development prospect of silicone MQ resin

China has included organic silicon materials in the national medium and long-term development plan as a key development of high-tech materials. In recent years, with the continuous development and improvement of organic silicon chemistry theory and technology, the organic silicon industry is moving towards the trend of high performance, multi-function, refinement, and composite. The raw material for synthesizing silicone MQ resin is mainly sodium silicate, which is cheap; when synthesizing, there is no need to strictly control the ratio between the components, and the synthesis process is simple. The modification of silicone MQ resin is also extremely easy, and it is convenient to prepare modified resins for special purposes and to develop functional silicone MQ resin. silicone MQ resins have great industrial application potential and a wide range of uses.
