LR-MQ Methyl MQ Silicone Nhựa

Nhựa Methyl MQ LR-MQ là sản phẩm cohydrolysis của tetraalkoxysilane (đơn vị Q) và trimethylethoxysilane (đơn vị m). LR-MQ có thể được coi là cấu trúc mạng ba chiều của polysilicate kết thúc trimethylsilane, chứa một số nhóm chức ethoxy và hydroxyl.

Description of LR-MQ Methyl MQ Silicone Resin

Its average molecular weight can be precisely adjusted by the ratio of M and Q units. Among LR-MQ silicone resins, the M/Q value is about 0.65, which is the water glass MQ silicone resin.

LR-MQ methyl silicone resin is a high-purity white powder or toluene liquid transparent liquid, and no volatile impurities are mixed in the production process. Therefore, this product contains almost no other impurities except trace aliphatic hydrocarbons. Since LR-MQ has uniform spherical particle size and extremely low fine powder content, it has excellent rheological properties (flow).

Applications of LR-MQ Methyl MQ Silicone Resin

  • LR-MQ methyl MQ resin, as a basic raw material, it can be used in defoamers and foam stabilizers, as well as addition pressure-sensitive adhesives and transparent reinforcing fillers;

  • In the field of high temperature defoamer, LR-MQ can effectively improve high temperature resistance, defoaming and foam suppression. Compared with silicate MQ, due to the lower molecular density of LR-MQ, the defoamer produced with it is more ideal than silicate MQ in terms of defoaming and foam suppression. In order to meet the better performance of the defoamer in the high-temperature system and ink system, LR-MQ has been specially treated with low molecular weight, so that the small molecular content is less than 0.1%, and the molecular uniformity ensures the stability of the emulsified product;

  • In the field of release, LR-MQ is a highly efficient and compatible release agent. Especially in polyurethane processing technology, this product can be used to prepare high-solid content release agent stock solution or solvent-based anti-adhesive agent, which has excellent mold release, avoids accumulation on the mold, and protects the smooth surface of molded parts. As a release agent for silicone polyurethane, the post-coating performance of molded parts mainly depends on the formulation of the release agent. It is recommended to test and adjust according to different application conditions;

  • Pressure-sensitive adhesive industry, LR-MQ is to improve the cohesive strength of silicone pressure-sensitive adhesive and adjust the peeling force.

Package & Storage of LR-MQ Methyl MQ Silicone Resin

  • In 20kg box or 25kg pail, 200kg drum.

  • Keep in cool, dry and ventilated place. Keep away from sunlight and fire sources. Keep in unopened containers, shelf life is 24 months from the date of production. It is shipped as non-hazardous substance.
