Detailed Product Description:
Incralac is a professional grade, acrylic-based protective coating formulated
specifically for coating the copper alloys, brass, and bronze. It provides a tough,
clear, glossy, tarnish-resistant coating which is unaffected by UV and continuous
Incralac is designed specifically for clear-coating copper alloys (brass,
bronze). It resists the attack of UV making it ideal for outdoor use. This
coating is applicable for either interior or exterior applications. Not for
constant water immersion such as bronze underwater gear on boats, however.
Appropriate for use on copper domes, brass plaques, bronze memorials,
ornaments, light fittings, door knobs and household utensils. Can also be
used on copper or brass range hoods or flues which are not subject to direct
flame. Is also applicable to aluminum and silver surfaces.
Originally developed by INCRA (International Copper Research Association)
for the protection and prevention from tarnishing of copper, brass, and similar
alloys. It is comprised of a solution of methyl methacrylate copolymer (acrylic resin)
incorporating benzotriazole, a very expensive but proven vapor phase corrosion
inhibitor for copper and its alloys.
Exposure to sunlight and some artificial lights can have adverse effects on the
useful life of polymeric coatings. UV radiation can break down the chemical bonds
in a polymer. This process is called photodegradation and ultimately causes cracking,
chalking, color changes and the loss of physical properties.
To counteract the damaging effect of UV light, UV stabilizers are added to the
formulation. UV stabilizers can be categorized by two general classifications—
ultraviolet light absorbers (UVA) and hindered amine light stabilizers (HALS).
HALS are extremely efficient stabilizers against light-induced degradation of most
polymers. They do not absorb UV radiation, but act to inhibit degradation of the
polymer. Significant levels of stabilization are achieved at relatively low concentrations.
HALS' high efficiency and longevity are due to a cyclic process wherein the HALS
are regenerated rather than consumed during the stabilization process.
A perfectly clean surface is critical to the performance of this coating. Surface
must be free of all previous coatings (paint remover may be required.) Polish
the surfaces with a conventional metal polish. Wash in warm soapy water to
remove residue. Since the soap off in clean hot water and dry thoroughly without
touching the surfaces with your hands.
Recommended application is with an air brush. No thinning is required. Stir
Contents thoroughly. Fill air brush cup and apply 1-2 coats for interior use
and coats for exterior use. Allow 30 minutes between coats. Dries to
touch in 30 minutes.
A pint will cover approximately 30 square feet when applied at a typical 13
Dissolves in lacquer thinner.
Ensure adequate ventilation during use. Highly flammable. Do not use if surface
temperature is below 55°F or in humid conditions.
Contents of 1-Pint comes packed in cone-top steel can for ease of pouring into
air brush cup.
