Instructions for Use

Mixing Instructions

N/A Standard can kit (mixed in separate container):
Stir or shake the base component to ensure any pigment, which may have settled on the bottom of the can, has been fully incorporated into the base. Do not stir or shake the base component longer than 15 minutes. Pour three volumes of base component into a separate clean container. Slowly add the one volume of catalyst to the three volumes base component. Mix by hand stirring, paint shaker or mechanical mixing to ensure the base/catalyst mixture is homogeneous. Do not shake or mechanically mix material for longer than 15 minutes. To the catalyzed primer, add approx 4 volumes (135%) of distilled or deionized water. Slowly add the water in one-third increments, mixing thoroughly after each addition, until fully incorporated and homogeneous. Be sure to scrape the sides and bottom of the container. Constant agitation of the material during spray application is recommended. The water is used to adjust the viscosity. Volumes of water needed may vary between 135 -150%.

For kit sizes contact your local Application Support Center.

1-Step Mixing (mixed in base container)

N/A Slowly add the entire catalyst component to the base component. Fill the can to the chime with distilled or deionized water. Secure the can lid and shake on paint shaker in an inverted position for 10-15 minutes.

Touch-Up Kits Available in 2TU and 4TU Configuration

N/A Touch-up kit configuration consists of an inner cup, which contains the 44GN098CAT catalyst/acetone blend located inside an outer cup (bottle) that contains the 44GN098 base component, and a container with water.

To mix, remove lid, pour contents of inner cup (catalyst) into outer cup (base), add supplied water. Replace lid and shake well by hand, approximately 2 minutes. Material is now ready to apply.

It is important to condition the paint for 24 hours prior to mixing by placing all materials in the shop or hangar, with ambient temperatures between 13 ºC and 35 ºC (55 ºF to 95 ºF). The minimum temperature of the paint components should be 13 ºC (55 ºF) prior to mixing.
