RANGE OF APPLICATION
ALEXSEAL® Accelerator for Finish Primer 442 is used to reduce the drying time of ALEXSEAL® Finish Primer 442. When using ALEXSEAL Finish Primer 442 directly on metal, the use of A4429 ALEXSEAL Accelerator Finish Primer 442 is not recommended.
Add up to 12.5% of A4429 to the catalyzed 442 epoxy primer, or 1 pint A4429 for each mixed gallon of base and converter.
A4429 also replaces that amount of the reducer. Mixing to achieve 12.5% reduction using A4429 is 2 quarts base, 2 quarts converter, 1 pint A4429.
Example 1:1:1 /4. Mixing for 25% overall reduction using this accelerator will require 12.5% reduction using A4429 and 12.5% reduction using R4042 Epoxy Primer Reducer. Example 1:1: 1 /4: 1 /4. Additional quantities of ALEXSEAL® Accelerator for Finish Primer 442 reduce pot life, and are not recommended.
