Mixing Instructions

Mix Ratio: 2:1 by volume (Part A to Hi Performance Catalyst / Part B)

Power mix Part A separately. Power mix Part B (Hi Performance Catalyst) separately. Then combine and power mix together until fully uniform. DO NOT MIX PARTIAL KITS.

Sweat-in time: Allow a 15-minute sweat-in period after combining parts before application.

Pot life: 1¼ hours at 75°F (24°C) · 2 hours at 60°F (15°C). Pot life shortens at higher temperatures and ends when the coating loses body and begins to sag.

Thinning by Application Method

Thinning is required to properly atomize the mixed material for spray application. Use only Carboline-supplied thinners — use of unauthorized thinners may adversely affect product performance and void product warranty.

Application Method Max Thinning Recommended Thinner(s)
Conventional Spray Up to 20% (25 oz/gal) Thinner 2, Thinner 76, or Thinner 225 E
Airless Spray Up to 20% (25 oz/gal) Thinner 2, Thinner 76, or Thinner 225 E
Brush As needed — "flow" the coating on Thinner 2, Thinner 76, or Thinner 225 E
Roller Not recommended for tank lining Use short-nap synthetic roller with phenolic core for non-tank applications only
Stripe / Weld Brush Pass Minimum 50% by volume Thinner 2, Thinner 76, or Thinner 225 E

Note: Prior to spray application, stripe brush all weld attachments and surface irregularities by thinning a minimum of 50% by volume.

Application Equipment Guidelines

Method Equipment Specification
Conventional Spray Pressure pot with dual regulators · 3/8" I.D. minimum material hose · .070" I.D. fluid tip · Appropriate air cap · ~50 psi at gun · 10–20 lbs. pot pressure
Airless Spray Pump ratio 30:1 min · 2.5 GPM output min · 3/8" I.D. material hose · Tip size 0.017"–0.021" · Output PSI 1,500–2,300 · 60-mesh filter · PTFE packings recommended
Brush Medium bristle brush. Apply light crisscross coat, allow ~5 min, then apply heavy crisscross coat. "Flow" the coating on rather than brushing out. Yields ~2.5–3.0 mils DFT per coat.
Roller Short-nap synthetic roller with phenolic core. Not recommended for tank lining applications except when striping welds.

Compatible Substrates & Surface Preparation

Remove all oil or grease from the surface per SSPC-SP1 before any surface preparation. See the full product data sheet for complete guidelines.

Substrate Surface Preparation Requirement
Steel SSPC-SP10 (Near White Blast). Surface profile: dense angular 2.0–3.5 mils (50–88 µ).
Concrete / CMU (Immersion) Must be cured 28 days at 75°F (24°C) and 50% RH or equivalent. Prepare per ASTM D4258 (cleaning) and ASTM D4259 (abrading). Voids may require surfacing.
Non-Ferrous Metals SSPC-SP16 or SSPC-SP17 as relevant. Anchor profile: 1.5 mils (37.5 µ) minimum. Remove all imbedded iron, chlorides, and contaminants that would interfere with performance.

Application Conditions

Condition Material Surface Ambient Humidity
Minimum 50°F (10°C) 50°F (10°C) 50°F (10°C) 0%
Maximum 90°F (32°C) 125°F (52°C) 110°F (43°C) 80%

Substrate temperature must be above the dew point at all times. Condensation on prepared steel can cause flash rusting and interfere with adhesion. Special application techniques may be required outside normal conditions.

Curing Schedule

Times based on 4.0–6.0 mil (100–150 µ) DFT. Excessive humidity or condensation during curing can cause discoloration and surface haze — remove any haze by water washing before recoating.

Surface Temp. Dry to Recoat Final Cure (Immersion) Maximum Recoat Time
50°F (10°C) 36 Hours 14 Days 30 Days
60°F (16°C) 24 Hours 10 Days 21 Days
75°F (24°C) 12 Hours 7 Days 14 Days
90°F (32°C) 6 Hours 5 Days 7 Days
⚠ Food-grade exposures require force curing at 225°F (107°C) for four hours. Raise temperature 30°F for every 30 minutes until temperature is reached.  •  If maximum recoat times are exceeded, abrade surface by sweep blasting or sanding before applying additional coats.

Limitations & Important Notes

  • Do not mix partial kits — always use complete kits to maintain the correct 2:1 ratio.
  • Roller is not recommended for tank lining applications except when striping welds.
  • When used as a tank lining or in enclosed areas, thorough air circulation must be maintained during and after application until fully cured. Use MSHA/NIOSH approved supplied-air respirator if vapor levels cannot be monitored.
  • This product contains flammable solvents. Keep away from sparks and open flames. All electrical equipment must be grounded per the National Electric Code. Use non-ferrous tools and conductive, non-sparking shoes in explosion-hazard areas.
  • Maximum system DFT must not exceed 18 mils (457 microns) total.
  • For immersion service temperature resistance, consult Carboline Technical Service — resistance depends on the specific exposure.
