Product Description

A high performance coating designed to protect steelwork from corrosion and concrete from ingress of moisture. Particularly suitable for coating the interior of water storage tanks, (must not be used on the interior of drinking water tanks) ships hulls, underwater steel structures, crude oil/sea water, blast tanks and the inside of pipes i.e. for sewerage hydroelectric stations etc. Attains maximum hardness and chemical resistance after 4 -5 days of application.

Characteristics: A combination of Epoxy Resin and pitch in a two-pack form with polyamide curing agent.

Advantages: Superior adhesion and water impermeability combined with excellent chemical, water and corrosion resistance. High build film with normal application.

Finish: Gloss.

Application: By brush or spray.

Thinning & Mixing: Incorporate both portions (base and catalyst) as supplied and stir thoroughly. Alternatively smaller quantities can be mixed strictly in accordance with mixing ratios indicated on the container. Allow to stand for 15-20 minutes before use.

Where necessary to ease brushing and for spray application, thin to the required consistency with Crown Two-Pack Epoxy Thinners. After thinning stir thoroughly before use.

Ensure that only sufficient material to use in one working day is mixed, as the “pot life” of the combined material is limited to 24 hours maximum.

Drying Times: Touch dry 4-6 hours. Recoatable within 24 hours in well-ventilated conditions. Do not allow the film to harden for more than 96 hours between coats to ensure good inter-coat adhesion. Full cure 4 -5days at ambient conditions.

Spreading Capacity: 3-4 m2/l when applied to a smooth, non-porous surface at 100-125 microns dry film thickness, subject also to operating conditions and techniques.

Equipment Cleaner: Crown Two-Pack Epoxy Thinners.

Colour range: Black and Brown only.

Pack Sizes: 4 litres (base and catalyst combined)

Availability: From Crown Depots in Nairobi, Mombasa and Kisumu and through Crown Stockists.
