ASI 504

MULTI-PURPOSE RTV SILICONE

BROAD ADHESION RANGE

ASI 504 Multi-Purpose Silicone can be used as both a sealant and adhesive for a variety of applications requiring a waterproof seal. It Is a paste-like, one component acetoxy silicone that cures to form a durable solid rubber when exposed to moisture in the air.

ASI 504 will not sag or slump so it can be applied to both vertical and overhead substrates without sagging. It can be used on both interior and exterior applications because it has excellent resistance to weathering, UV degradation, yellowing, etc. ASI 504 will adhere to most metals, woods, porcelain, ceramic, fiberglass, glass, and a variety of substrates not listed.

Strength will start to develop immediately and continue increasing tor 7 days after application. ASI recommends testing strength and adhesion on the 7th day. ASI 504 suggested application temperature range: -35°F to 150*F. ASI 504 can be used at temperatures higher than 400°F for intermittent periods. Testing should be done to confirm temperature requirements are met.
