A single pack sealer designed for use as part of an approved Altex Coatings Ltd single pack, solvent borne intumescent coating system. It is applied to cured approved intumescent coatings to protect it from moisture ingress, so that steel may be stored outside with enhanced weathering properties.
It can minimise solvents in the subsequent finish coats from re-entering the approved intumescent film.
When correctly applied to partially cured approved intumescent, Pro~Seal allows residual solvents, retained within the approved intumescent to transpire through the film. Full cure (hardness at Shore D-50) may then be achieved for the intumescent film.

Pro~Seal is the first intumescent seal coat that significantly reduces those risks that can be encountered with approved single pack, solvent borne intumescent coatings:

  • Solvent entrapment & resulting blistering
  • Rain damage
  • Solvent softening from finish coats
  • Finish coat incompatibility

FEATURES:

  • Rapid dry – dust free typically within 30 minutes
  • Extended time to finish coat. May be left through the entire construction phase for finish coating (with suitable preparation) at project completion
  • Easy to use – single component coating
  • Brush, roller, or spray application
  • Excellent resistance to solvents (once cured) permitting application of a wide range of two component polyurethanes for both interior and exterior exposure
  • Cures well at low temperatures
  • Promotes the cure of the approved intumescent coating, thus ensuring cure can be achieved with minimal risk of moisture damage
  • May be finish coated with a wide range of solvent borne or water borne finish coats
