200-257 is a single-component, oxime-cure silicone for use in applications where the coating needs to settle into small crevices and hard to reach areas while maintaining consistency without sagging or running. Coating intricate electrical and mechanical devices, insulating electrical terminals, and thin section potting are a few of the many applications in which our 200 Series products may be used. These products have good adhesion to most common substrates, and will not corrode aluminum, copper, and ferrous metals (with adequate ventilation).

• Utilizes a moisture cure system at room temperature to result in a tough, resilient, silicone rubber
• Retain enough thixotropy to prevent leakage during the cure cycle
• Superior UV resistance

200-257 has a viscosity of 70,000 – 110,000 cPs and skins over in 5 – 20 minutes. As a high viscosity sealant, it can be applied on vertical surfaces without sagging. 200-257 also has superior gap-filling properties designed to offer superior quality and long-term durability, particularly upon exposure to hostile environmental conditions.
