Triangle Coatings Company Logo
TriPrime™is a high-solids, solvent-reducible primer for iron and steel that dries quickly. It is intended for use in shop and CEM applications, as well as under all common finishes, including polyurethanes. TriPrime™ is intended for hand-cleaned iron and steel SSPC-SP1, SP2, or SP3, and provides active corrosion inhibition and undercutting protection. It is intended for HVLP and air assisted airless systems, but it can also be used with conventional or airless systems where legal. Most systems require thinning; see the instructions under "Recommended Thinning." Alkyd, silicone alkyd, and acrylic topcoats are all recommended.

Application Data

Surface Preparation:
TriPrime 902P Series primers are designed for use over hand cleaned iron and steel, SSPC-SP1, SP2 or SP3

  • Surface and ambient temperatures must be above 45° F. Recommended maximum surface temperature is 120° F. Temperatures above 95° F may require the use of a “slow” solvent. Contact Triangle for more information.
  • Surfaces must be 100% free of all contaminants except small amounts of fully adherent rust. All loose and scaling material, grease, oils, asphalt, silicones, dirt, dust, chemical contaminants and moisture must be removed.
  • Existing paint should be removed, SSPC-SP2 Completely sound paint may be left, but service life of new system will become that of the existing paint
  • and that will be less than new products alone.
  • Temperatures must be +5° F above dewpoint. Fresh primer must be protected from all moisture until rainproof as per chart above.

REQUIRED THINNING:
Designed for 25 - 30% reduction with 30-003 PCBTF in VOC regulated areas and 34-001 xylene in unregulated areas.
Thinner: 30-003 PCBTF or 34-001 Xylene
Brush or Roller: Thin as required
Airless Spray: Thin as required
Conventional Spray: Thin as required

Applications

This coating may be applied by conventional or airless spray application methods. Apply using crossing pattern.
