Description:

ASI 502 High Performance 100% Silicone Sealant Adhesive is a one-part, moisture- curing RTV (room temperature vulcanizing) silicone that cures to a strong, silicone rubber that maintains long-term durability and flexibility. ASI 502 contains no solvents or isocyanates which makes it VOC compliant. Due to the formulation, ASI has received numerous accolades for its tensile strength, adhesion, and overall performance. 

ASI 502 is a non-slump sealant and can be applied to vertical or overhead surfaces without flowing or sagging. Because ASI 502 is a 100% silicone sealant, it has excellent resistance to weathering including ozone, ultra-violet radiation, freeze-thaw conditions and airborne chemicals. ASI 502 can be applied to surface temperatures from -18°C to +50°C (0°F to +120°F) and after curing, withstands constant operating temperatures from -57°C to +205°C (-70°F to 400°F).

24 Tubes per case.

Directions:

ASI 502 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 in 24 hours (1/8” bead) and reaches its maximum adhesion in 7 days. Higher humidity accelerates curing. Tooling, if neces- sary, should be done before skinning takes place. In applications where partial or total confinement of sealant is prevalent, the time required for proper cure is generally lengthened by the degree of confine- ment.

Surface Preperation:

All surfaces should be clean and dry. If necessary, bonding surfaces can be solvent wiped with naphthas, ketones or chlorinated solvents. Specific solvents would include xylol, toluol and mineral spirits. In case of plastics, determine suitability of solvent prior to use. Allow surface to dry thoroughly before applying sealant. Do not solvent wipe with alcohols or oil-containing solvents such as Varsol. Priming for ASI 502 is not normally required for applications to nonporous surfaces. Unprimed adhesion can be easily tested by applying a small trial bead and allowing 7 days for maximum adhesion to occur. If primer is required, contact ASI.

Safety Precautions:

ASI 502 releases small amounts of acetic acid during cure. Adequate ventilation should be provided with extensive use of this sealant. On direct contact, uncured sealant may irritate eyes. Flush eyes well with water and call a physician. Avoid prolonged contact with skin.

Storage:

ASI 502, when stored in original, unopened container at or below 32°C (90°F), has a shelf life of 12 months from date of shipment.

FDA STATUS:

ASI 502 is permitted under regulations of the Food and Drug Ad- ministration where incidental food contact might be involved. FDA Regulation number is 175.105
