Product Description

SiSR-200 is a series of MQ silicone resins, which is a co-hydrolysis product of tetraalkoxy silane (Q unit) and trimethylalkoxy silane (M unit).

Application
• As a reinforcing material for condensation type liquid silicone rubber(LSR).
• To formulate mold release agents for a variety of materials plastics, polyurethanes. 
• To prepare heat-resistant and alkali-resistant silicone defoamer. By adding high-viscosity hydroxyl silicone oil and silicone MQ resin to synthesize a network polymer with a high degree of branching, so as to improve the heat resistance and strong alkaline resistance of the defoamer.
• As an ingredient of polishing formulation to enhance the hydrophobicity of automotive care and home care systems.
• Silicone Pressure Sensitive Adhesive(SPSA):
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.
• Film-forming in personal care and cosmetics. For cosmetic applications, we recommend SiSR-200 from SUNSIL™ line.

Package
25KG, 50KG carton drums.

Storage
• Sealed storage in original containers at 5-35ºC temperature.
• Shelf Life: 24 months.
• Storage beyond shelf life doesn't mean the product is no longer usable, but a trial test is necessary for quality assurance.
