INDUSTRIAL GRADE SELF-LEVELING SILICONE

BONDS, SEALS, FILLS GAPS, ENCAPSULATES & ADHERES

ASI 505 Self-Leveling RTV Silicone is a one-component, moisture cure, flowable material designed for a variety of potting, coating, sealing and waterproofing applications.

Once applied, ASI 505 will begin skinning in 8 minutes and continue curing to form a flexible, durable rubber that bonds well to a wide variety of substrates. ASI 505 will resist a wide temperature range (-70°F to 400°F) and will not degrade when used in exterior applications or under water. It is extremely UV resistant and will not shrink, crack or dry out long-term. ASI 505 Contains no solvents and is VOC compliant.
