Price:
$38.95
Chemical Name:
Incralac Clear Coat
Synonyms:
Clear Coat for Copper, Brass, Bronze

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

 

exterior exposure.

 

 

 

 

Typical Applications:

 

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.

 

 

 

 

Background:

 

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.

 

 

 

 

Application Notes:

 

 

 

 

Surface Preparation:

 

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.

 

 

 

 

Application:

 

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.

 

 

 

 

Coverage:

 

A pint will cover approximately 30 square feet when applied at a typical 13

 

micron thickness.

 

 

 

 

Clean-Up:

 

Dissolves in lacquer thinner.

 

 

 

 

Precautions:

 

Ensure adequate ventilation during use. Highly flammable. Do not use if surface

 

temperature is below 55°F or in humid conditions.

 

 

 

 

Size/Packaging:

 

Contents of 12-ounces comes packed in aerosol can.
