Conductive Coatings

ELECTRICALLY CONDUCTIVE ACRYLIC AND POLYURETHANE PAINTS

G. CONDUCTIVE SYSTEMS

GENERAL DESCRIPTION

TECKNIT manufactures a highly conductive

acrylic and polyurethane paints filled with silver.

These coatings provide a cost effective method

for shielding and grounding plastic enclosures,

which are susceptible to EMI, and other applica-

tions requiring a flexible protective shield.

SHELF LIFE AND STORAGE

RECOMMENDATIONS

It is recommended the ACRYLIC-1 paint be used

within six months of the manufactured date and

the POLYURETHANE paints be used within nine

months of the manufactured date. All conductive

coating containers should be stored in the

“upside-down” position and at a temperature

between 50°F and 86°F [10°C and 30°C].

NOT FREEZE CONDUCTIVE COATINGS.

PAINT PREPARATION

Before and during use, CONDUCTIVE COATINGS

should be thoroughly stirred. Each component of

the two and three part polyurethane coatings

should be stirred prior to combining. The compo-

nents of the two and three part systems are sup-

plied as a premeasured kit.

SAFETY AND USAGE CAUTIONS

TECKNIT CONDUCTIVE ACRYLIC AND

POLYURETHANE PAINTS contain a flammable

solvent and should be used in a well ventilated

area. Avoid direct skin contact and inhalation of

vapors. Prevent contact with eyes. Do not use

near open flame. Industrial use only

. Some indi-

viduals may experience skin irritation - wash with

mild soap and rinse with clear water. Contact

physician should ir

ritation occur.

SURFACE PREPARATION

o ensure the best electrical and mechanical reli-

ability, remove all grease, oils, dirt, mold releases

and foreign matter. Preparation should be in

accor

dance with standar

d practice for one-

coat painting. Recommended cleaning agent

is alcohol.

RECOMMENDED THINNING

THINNING IS REQUIRED FOR THE ACRYLIC-1

PAINT to achieve the proper consistency when

using spray equipment. Thinning increases drying

time by two or three fold but assures “wetting

out” of the ACRYLIC-1 paint offering optimum

electrical properties. Thinner should never exceed

25% by volume. The POLYURETHANE coatings

can be used with spray equipment as supplied. It

is not recommended to thin the POLYURETHANE

COATINGS. Toluene can be used for solvent

cleaning the ACRYLIC-1.
