Storage and Cleanup
Shelf life is 6 months, in original, unopened
factory containers, under normal storage
conditions of 55° to 85° F. Do not store in direct
sunlight. Keep drums tightly closed when not in
use. Cured product may be disposed of without
restriction. Excess liquid ‘A’ and ‘R’ material
should be mixed together and allowed to cure,
then disposed of in the normal manner.
Safe Handling of Liquid Components
Use caution in removing caps and bungs from the
container. Loosen caps and bungs first to let any
built up gas escape before completely removing.
Avoid prolonged breathing of vapors. In case of
chemical contact with eyes, flush with water for
at least 15 minutes and get medical attention.

Polyurethane Foam Systems: Guidelines for
Safe Handling and Disposal” publication AX-119

Caution
Polyurethane products manufactured or
produced from this liquid system may present a
serious fire hazard if improperly used or allowed
to remain exposed or unprotected. The character
and magnitude of any such hazard will depend
on a broad range of factors which are controlled
and influenced by the manufacturing and
production process, by the mode of application
or installation and by the function and usage
of the particular product.
