MSK MQ808 methyl silicone resin

MQ-808 is a methyl MQ silicone resin produced by water glass method. It can be seen as a three-dimensional network structure of polysilicic acid terminated by trimethylsilane group, containing some ethoxy and hydroxyl functional groups. MQ-109 is a high-purity white powder or toluene liquid transparent liquid, which will not be mixed with any volatile impurities in the production process. At the same time, it has uniform spherical particle size, extremely low content of fine powder, and excellent rheological properties (flow).

  • MQ-808 Product description

产品应用

●缩合型压敏胶及缩合补强填料和泡沫稳定剂

●离型/脱模领域,MQ-808是一种高效高相容的脱模剂。特别是聚氨酯加工工艺中,本品可用于制备高固含量的脱模剂原液或者溶剂型抗粘剂,具有优异的脱模 ,避免在模具上积聚,保护成型件表面光滑。

●在高温消泡剂领域,能有效的改善耐高温性、消泡性和抑泡性。与硅酸酯类 MQ 相比较,由于 MQ-808分子紧密度更低,所以用它生产的消泡剂在消泡和抑泡性上,都要比硅酸酯的 MQ 效果理想。为满足消泡剂在高温体系和油墨体系里的更好表现,特别进行了低分子的处理,使小分子含量小于 0.1%,以及分子的均一性,保证乳化后产品的稳定性。

●压敏胶行业, 改善有机硅压敏胶的内聚强度以及调整剥离力。
