POLY-CHEMCURE PC-110
RUST INHIBITIVE EPOXY PRIMER
PRODUCT DESCRIPTION
PC-110 is a two component, high build Polyamide Epoxy Rust Inhibitive Primer designed for use as a primer for our Epoxy and Polyurethane Topcoats. PC-110 helps prevent edge failure and film under-cutting of steel surfaces exposed to corrosive atmosphere and chemically aggressive environments. PC-110 can be used where an extended recoat period of up to 6 months is needed. Proper cleaning of the primer must be done after extended time without a top coat to remove any dust, dirt, grease or oil that may have contaminated the surface.
PRODUCT FEATURES
1. Excellent rust preventing properties 5. Outstanding adhesion and "wetting out"
2. Excellent resistance to "under cutting" ability
3. Good flexibility, impact and abrasion resistance 6. Easily applied by conventional or airless spray
4. Long recoat up to 6 months 7. Excellent film build to protect sharp edges
8. Great shop coat primer for fabricators

CHEMICAL RESISTANCE
Good resistance against alkalies, salts, fresh or salt water, and some acids and solvents.
SURFACE PREPARATION
Remove all dirt, grease, oil, chemical contaminants, soil, and any other foreign matter before abrasive blast cleaning. Prepare and paint only clean, dry surfaces in accordance with Steel Structures Painting Council (SSPC or National Association of Corrosion Engineers (N.A.C.E.) specifications.
1. Steel (Non-Immersion)
a. Corrosive Service: Sand blast to a "Near-White" blast finish as outlined in SSPC10-63T or
N.C.C.E. No. 2 specification.
b. Mild Service: Sand blast to a "Commercial" Blast finish as outlined in SSPC-SP6-63 or
N.A.C.E. No. 3 specification.
2. Steel (Immersion)
Sand blast to a "White Metal" blast finish as outlined in SSPC-SP5-63 or N.A.C.E. No. 1
specification.
3. Galvanized Steel
Surface must be clean and free of grease, dirt, and other foreign matter. Surface should be
high pressure water cleaned, or solvent degreased per SSPC-SP1-63 specification. Then,
prime with VE-180 Vinyl Wash Primer per label instructions, or Abrasive Sweep Blast to achieve
a surface anchor profile.
MIXING INSTRUCTIONS
Stir each component to a uniform consistency, using a variable speed explosion proof drill with Jiffy Mixer. Make sure any pigment settled to the bottom is incorporated. Do not vary proportions. Poly-Chem PC-110 Primer is prepared by mixing 4 parts Base (Part A) to 1 part Hardener (Part B) with a Jiffy Mixer. Be sure material is thoroughly mixed together. Allow an induction or "sweat in" time for 30 minutes before using.
POT LIFE
The pot life of PC-110 is about 8 hours at 75°F. At 90°F, the pot life is reduced to about 5 hours.
APPLICATION PROCEDURE
PC-110 can be applied by brush roller or spray.

CURE TIME
Temperature Tack Free Minimum Recoat
90°F 2 hours 4-5 hours
75° F 3 hours 5-6 hours
50°F 8 hours 18-24 hours
Time will be longer for films thicker than 4 mils. When spraying, use a 50% overlapping crosshatch pattern to minimize the occurrence of pinholes. Do not apply to surfaces below 50°F. or above 120°F. Do not apply over dew or frost. Do not apply if the temperature is within 5° of the Dew Point.
For safety reasons and to assist curing of the wet film, proper ventilation is necessary throughout application and cure. When using a pigmented Finish Coat, be sure the batch numbers are all the same to provide a uniform color.

CAUTIONS
PC-110 Epoxy is flammable. Keep away from all sources of ignition during mixing, application and cure. The HARDENER (Part B) and mixtures of BASE (Part A) with HARDENER (Part B) can cause eye and skin burns as well as allergic reactions. The use of goggles, fresh air masks or NIOSH approved respirators, protective skin cream and protective clothing is a recommended standard practice when spraying coatings. This product is sold without warranty as to performance expressed or implied. Users are urged to make their own tests to determine the suitability for their particular conditions.
