ASI 405 meets the requirements of MIL-A-46146A.†

ASI 405 meets the U.S. Federal specifications TT-S-001543A and TT-S-00230C.

Uncured product contact irritates eyes. In case of contact with eyes, immediately flush eyes with water for 15 minutes. If irritation persists, get medical attention. Wearers of contact lenses should not handle lenses until all sealant has been cleaned from the fingertips; sealant will transfer to lenses and cause severe eye irritation. To clean from the skin, wipe very thoroughly with a dry cloth or paper towel before washing with soap and water. Product releases methanol and ammonia during application and curing. Use mechanical ventilation to stay below TLV of 25 ppm ammoni. Uncured product contact may irritate the skin. Materials Safety Data Sheets are available upon request.
