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.

Any flammability

rating or reference contained in this or other

PolyLEVEL

400 literature is not intended

to reflect hazards presented by this or any

other material under actual fire conditions.

These ratings are used solely to measure and
