This urethane diol modifying resin imparts improved stain resistance to the forced dry (thermoset) wood clear coat formulation below.
What makes this formulation unique, is the absence of neutral-izing amines.
As a result, a free acid catalyst may be used (Nacure 155) and lower temperature cures may be achieved. A potlife of 24-48 hours is possible.
