This product can be used with nonionic or anionic pigments, melamine resins if pH is raised to alkaline side with aqueous ammonia, and various nonionic or anionic softeners as desired.

Silicone defoamers may be added if foaming affects the application.

Any additional chemicals may affect non-yellowing properties.

Recommended cure temperature is 300° F or higher.  If a lower cure temperature is required, the addition of an acid catalyst, such as ammoniam sulfate at 0.25-0.50%owb may be used.
