DESCRIPTION

        ASI 692 Hi-Temperature Red Gasket Maker is a one-part, moisture-curing, RTV (room temperature vulcanizing) silicone that cures to form a tough rubber gasket. ASI 692 was specially formulated to be used as a formed-in-place gasket where operating temperatures up to 500°F continuous and 600ºF intermittent. ASI 692 will remain permanently flexible and provides excellent resistance to aging, vibration, shock and oils.

TYPICAL USES

        The primary use for ASI 692 is formed-in-place gaskets in high temperature applications to replace conventional paper and cork gaskets. Such uses include:

Automotive
     axle housings
     water and oil pump seals
     valve covers
     thermostat housings
     bearing cap seals
     timing chain covers
     fuel pumps to blocks
     solenoid covers

Industrial
     pump and compressor gaskets
     appliance door gaskets
     humidifier gaskets
     air conditioner gaskets
     repairing torn silicone rubber sheets
     ductwork gaskets
     dust collection components
     wire and cable insulation
 

DIRECTIONS

        ASI 692 is ready to use and requires no mixing or additives. The cure mechanism begins as soon as the sealant comes in contact with the air. At conditions of 25°C (77°F) and 50% relative humidity, the sealant will skin in 10 minutes and fully cure within 24 hours (1/4" bead).
 

SURFACE PREPARATION

        All surfaces should be clean and dry. It is recommended that bonding surfaces be solvent wiped with a naphtha, ketone or chlorinated solvent. Suitable solvents include xylol, toluol and mineral spirits. Do not solvent wipe with alcohols or oil-containing solvents such as Varsol. For gasket applications, apply an even bead, with a diameter of 1/8" or less, to one surface, making certain to surround all bolt holes. Press, do not slide parts together, and torque normally. If removal of ASI 692 is necessary, it can be wiped off surfaces to be mated when uncured. After the material cures, it can be abraded or scraped from the surface. ASI 692 is not recommended as a gasket for cylinder heads, manifolds or in direct contact with fuels.
 

PRIMING

        ASI 692 is formulated for primary use as a formed-in-place gasket material because substrate release, rather than adhesion, is required. If good adhesion should be required, a primer should be used. Consult primer techsheet or contact ASI for technical assistance.
 

SAFETY PRECAUTIONS

        Adequate ventilation should be provided with extensive use of this sealant. On direct contact, uncured sealant will irritate eyes. Flush eyes well with water and call physician. Avoid prolonged contact with skin.
 

STORAGE

        ASI 692, when stored in original, unopened container at or below 32°C (90°F), has a shelf life of 12 months from date of shipment from American Sealants, Inc.
 
 

PACKAGING

        ASI 692 is supplied in (10.2 fl. oz.) caulking cartridges, (42 lb.) pails and (495 lb.) drums.
