Always use a calibrated and graduated clear paint mixing cup to mix the material. They are used for accurately mixing paints, resins and lacquers to the correct mixing ratio.
Although it is possible to blend manually through vigorous stirring, for best results ensure the hardener is added slowly under mechanical stirring conditions. This will ensure optimal consistent results and avoid air bubbles. This is especially important when mixing high Gloss Sheen levels.
When not in use keep the container well closed in dry conditions. Always close tightly after taking the quantity required for catalyst.
The introduction of crosslinking agent in a product may result in an increase in viscosity. Do not exceed the maximum blend.
