A chemical-resistance gloss finish for
use with Epoxy Primers and Undercoats in laboratories; Chemical or
industrial plant where resistance is required against spillage or
fume attack from a wide range of chemicals and solvents. Epoxy Finish
is fast-drying and abrasion resistant, and is especially effective
against strongly alkaline conditions. While its main use is in protective
systems over metallic surface it can be used in conjunctipn with Epoxy
Primer White for masonry walls and concrete surfaces in areas where
chemical fumes and spillage are experienced. It is available in a
short range of colour-fast shades, which enable the decorative appearance
of many industrial projects to be enhanced.

SURFACE PREPARATION
Epoxy Bildcote
is normally applied over Zinc Rich Primer Two-Pack, Epoxy Zinc
Phosphate Primer Two-Pack, Epoxy Protective Primer Two-Pack.
The protective primer must be clean, sound and firmly adhering.
(Polyvinyl butyral shop primers should not be used under conditions
of continuous immersion or in conjunction with cathodic protection).
The removal of contamination must include washing with fresh
water to remove soluble salts.
PAINT SYSTEM
Net Work
Normally applied over surfaces prepared
and primed with appropriate Epoxy Primer, or over Epoxy Bildcote
Two-Pack depending on the surface and the system used. Previously
painted two - pack epoxy Check coating does not soften on test
area System before commencing work. If softening occurs, strip
coating and treat as new work. Surface must be dry and in good
condition. Brush blasting may be necessary with old, well-cured
existing coatings. Spot prime and bring forward any bare areas
as specified. All surfaces must be clean, dry and free from
grease, oil and other contraminants. The removal of contaminants
should include washing with fresh water to remove soluble salts.
PAINT SYSTEM
CHEMICAL AND WATER RESISTANCE
Epoxy systems applied to correctly
prepared surfaces will withstand immersion in alcohols (except
methanols), esters, aldehydes, ketones, hydro-carbon and chlorinated
solvents, mineral and vegetable oils, alkalis (except dilute
ammonia solution) and sea water; and splashing with most common
mineral acids, dilute ammonia solution and water. Where resistance
to immersion in fresh water and dilute acids is required as
Chlorinated rubber system is preferred.
Note:
It is recommended that reference
is made To ACCI for guidance on the suitability of Epoxy system
for specific conditions.
