GENERAL DESCRIPTION
Pruett-Schaffer’s 11-Series coatings are low gloss, solvent based, two component amine-cured epoxy phenol novolacs. For best results, apply by air assisted or airless spray. Other methods will take more coats to achieve desired film thickness. Epoxy-Phenolic coatings serve as high performance linings or maintenance coatings for use over a wide variety of substrates that are subjected to extremely hostile environments.
RECOMMENDED USES
11-Series epoxies are premium, heavy duty, corrosion preventative, industrial maintenance coatings, and should only be applied by professionals. They are recommended for use on substrates exposed to chemical splash or mist, heat or steam, solvents, acid or alkali, water, salt, oils, and fuels. These coatings have excellent adhesion, exterior durability (but chalk), and abrasion resistance (if heat cured). The in-service temperature limit is 400 0F, wet or dry. They are very high in solids, allowing a thicker film build in one pass without sagging; and perform well over hard to protect sharp edges and complex geometric shapes.
SURFACE PREPARATION
For severe service, metal substrates should be degreased and blasted to SSPC-SP-10 white metal blast, 1.5
0.5 mil profile. An SSPC-SP-6 commercial blast may be used where conditions are less aggressive.
MIXING INSTRUCTIONS
Thoroughly mix 4 parts by volume A component with 3/4 part 11-B Hardener. Box while mixing at slow speed to avoid entraining air into the paint. Use at once, there is no induction time. Do not reuse previously used mixing containers; partially cured material will greatly accelerate the cure of the freshly mixed paint resulting in dramatically reduced pot life. Clean mixing blade after each use.
THINNING
Under normal conditions no thinning is necessary. If desired, thin with xylol. Add a little at a time with constant gentle agitation to a maximum of 5% by volume.
APPLICATION EQUIPMENT
Airless or air-assisted airless is the preferred method of application & will result in the best appearing finish.
Use .015-. 017-inch spray tip size. The recommended dry film build per coat is 51/2 to 8 mils when sprayed, which will yield a 4 to 6-mil dry film in one pass. Recoat if desired for higher film build and better protection. They may be applied by brush or roller with 1/4 " nap or less.CURING TIMES & TEMPERATURES
Air dries set-to-touch in 3 hours and tack free in 4 to 5 hours at 70 0F. Recoating must be done after 5 hours air dry and before 24 hours air dry time or reduced adhesion may result. Ultimate hardness and chemical resistance develops if heat cured for 1 hour at 350 0F.
CLEANUP
Clean equipment with xylol or toluol before the film cures.
ENVIRONMENTAL
These products meet current air pollution regulations regarding hydrocarbon and ozone reactive emissions. They are VOC compliant for most industries, are zinc and chromate free, and comply with current federal regulations regarding the use of lead in paint.
