Powder coating composition.

摘要

A powder coating composition contains a polymeric binder and greater than 40 percent by weight of a coalescing additive component containing at least one coalescing agent which is a solid at ambient temperature, the percentage based on the total weight of the binder and the coalescing component of the composition. The coalescing additive component is adapted to promote flow and fusion of the binder into a substantially coalesced film with the application of heat and be substantially volatilized from the film during coalescence.
