Protection of concrete, metal, ceramic, masonry, glass and other surfaces. Storage-tank linings, industrial floor resurfacing, laboratory, food and scientific equipment protection. Coating of machinery, industrial and marine equipment, electric components, electronic assemblies, circuit boards.

• Surfaces must be thoroculegan hanld ydr y for good adhesion. Sandblasting, sanding, etching, washing or degreasing are recommended. Special treatment of metals and other surfaces may be desirable in some cases.
• Abocoat/Abocure mixing must be thorough. A power mixer, a spatula or paddle are all adequate if properly used.
• Pot life is the time the Abocoat/Abocure blend remains workable, before hardening, in the mixing container. Do not mix any more than can be used up within 30-40 minutes. If solvent is added for brushing or spraying the pot life is proportionately increased to several hours.
• An Induction Period (waiting period in the mixing container, after mixing) of at least 5 minutes is advised to prevent "tacky hardening" of thin layers exposed to atmospheric moisture during application.
• Application is simple. Brushes, rollers, sprayguns are all adequate for different purposes.
• Hardening, Curing, Temperature. The 8501-1 System hardens by chemical reaction rather than by drying. The hardening reaction generates heat and is accelerated by large bulk and heat. Low temperatures have a retarding effect. Cure completes the reaction and continues for 5-10 days at room temperature, or just hours (or even minutes) with heating. Viscosity is also decreased by heating and increased by cold. Thus, better flow, wetting and adhesion, as well as faster hardening, are obtained on a warm surface, or with a warm resin.

Hardening Time:
Tack-free within 2 hours approximate at 25°C. Hardens faster with heating, which can reduce process to a few minutes. Low temperatures slow hardening (too slow under 10°C).

Cure:
Optimum properties are reached within 4-8 days at room temperature, or faster with heat. For instance, 2-3 hours are sufficient at 100°C (212°F).
