Abstract:
Sag control compositions, methods of forming sag control compositions, and methods of forming coating systems that include at least one coating layer including urea crystals of such sag control compositions are provided herein. In an embodiment, a sag control composition includes urea crystals and a non-polymeric organic solvent. The urea crystals include the reaction product of a polyisocyanate and a mono-amine. The sag control composition is a stable mixture with a single phase at a temperature of about 21 C. based upon visual observation for a period of at least 10 minutes after forming the mixture.
