Advantages

  • VOC level : 31 g/L
  • Fast dry speed
  • Early water resistance without harmful odors.
  • Long pot life
  • Excellent adhesive properties, allowing application on other firm and hard coating, as well as a good bond to the substrate
  • Superior chemical resistance
  • Superior U.V. resistance
  • Outstanding appearance
