Description

This is the hardener for our Aero-Thane top coat. Mix 3 parts Aero-Thane to 1 part U-865 Catalyst.

An aliphatic polyisocyanate in a solvent blend. It is hydroscopic (sensitive to moisture) and will start to polymerize immediately in the presence of moisture. Therefore it is very important the catalyst container cap is kept tight in storage and in between use.

Containers are packaged with a nitrogen purge to eliminate moisture and should be used as soon as possible after the cap is first removed and the nitrogen purge released.
A milky appearance, gel in the bottom of the container or swelling of the seals are indicators of moisture reaction with the catalyst and should not be used because there will be no polymerisation with the base component.

After each opening, the aluminum foil seal in the cap should be checked for damage and a new aluminum foil seal cut if necessary to prevent reaction with impurities in the paper gasket. The suitability of urethane catalyst can be checked by mixing 1 spoon to 3 spoons of the base component and brush a small test patch. After aging 7 days, rub 50 strokes with an MEK soaked rag. Any good quality, properly polymerized urethane coating will not be softened and the pigment transferred to the rag.

Guarenteed 2 years from date of manufacture, unopened in protected storage. Avoid extended storage above 100F Not affected by freezing.
