Application

  • Tank linings for primary and secondary containment.
  • Roof coatings for metal decks.
  • Steel tanks, silos and pipes.
  • Hail, bird and traffic protection over polyurethane foam.
  • Encapsulant for styrofoam and other types of floatation.
  • Liner for concrete tanks, ponds, lagoons, reservoirs, dykes, irrigation ditches, tunnels, barges, etc.

Description

A spray applied, elastomeric coating that can be put into service in minutes. It provides a flexible, PVC like, monolithic elastomer that is extremely tough, with good physical properties, has a high degree of thermal and hydrolytic stability and excellent water and chemical resistance.

Features:

  • A seamless membrane that can be handled and walked on one minute or less from the time it is sprayed.
  • Hydrophobic and therefore unaffected by damp substrates when creating non-bonded liners. It can be sprayed at temperatures as low as -30°C with minimal effect on tack free time.
  • Due to the almost instantaneous gel of the spray, it can be built up to any thickness in one application including vertical and overhead applications. This eliminates the need for multicoat applications.
  • 100% solids, no solvents, no VOCs.
  • The cured elastomer has a high thermal stability with constant working temperatures up to 130°C and intermittent temperatures up to 160°C.
