Uploaded by Jasmine

Carboguard® 893 is a cycloaliphatic amine epoxy high-solids corrosion-resistant primer and intermediate coating for steel and inorganic zinc primer systems. It can be used as a primer or intermediate coat and topcoated with high-performance finish coatings. Key properties include excellent corrosion protection, strong film build and edge protection, and good abrasion resistance, with curing down to 40°F (4°C). The sheet specifies dry film thickness ranges, VOC-compliant colors, surface-prep requirements, mixing/thinning guidance, and temperature performance limits. Performance data includes salt fog, water fog, hardness, abrasion, and weatherometer results.

Resistance Limitations Topcoats Cycloaliphatic Amine Epoxy High solids corrosion resistant primer and intermediate. Used either as a primer or an intermediate coat over steel and inorganic zinc primers. Can be topcoated with a broad variety of high performance finish coats. • Excellent corrosion protection • Excellent film build and edge protection • Used as a primer or an intermediate coating • Good abrasion resistance • Cures down to 40°F (4°C) • VOC compliant to current AIM regulations Gray (0700); Yellow (0600): White (0800) Eggshell Self-priming. May be applied over organic and inorganic zinc rich primers. A mist coat may be required to minimize bubbling over zinc rich primers. 4-6 mils (102-152 microns) per coat 3-6 mils (76-150 microns) for mild environments and as an intermediate coat over zinc rich primers. 4-6 mils (102-152 microns) for more severe environments. Do not exceed 10.0 mils (250 microns) in a single coat. Excessive film thickness over inorganic zincs may increase damage during shipping or erection. By Volume 77% +/-2% 1235 ft²/gal at 1.0 mils (30.3 m²/l at 25 microns) 309 ft²/gal at 4.0 mils (7.6 m²/l at 100 microns) 206 ft²/gal at 6.0 mils (5.1 m²/l at 150 microns) Allow for loss in mixing and application. As Supplied : 1.6 lbs/gal (195 g/l) Thinner 230 : 13 oz/gal = 2.1 lbs/gal (252 g/l) Thinner 2 : 16 oz/gal = 2.2 lbs/gal (261 g/l) Thinner 33 : 32 oz/gal = 2.7 lbs/gal (329 g/l) These are nominal values and may vary slightly with color. *Maximum thinning for 250 g/l restricted areas is 12 oz/gal with Thinner 2, and 11 oz/gal with Thinner 33 or 230. Use Thinner 76 where nonphotochemically reactive solvents are required (up to 11 oz/gal) Continuous: 200°F (93°C) Non-Continuous: 250°F (121°C) Discoloration and loss of gloss is observed above 200°F (93°C) . Epoxies may lose gloss, discolor and chalk when exposed to sunlight. Not recommended for immersion service. May be coated with Acrylics, Epoxies, Alkyds, or Polyurethanes depending on exposure and need. Carboguard® 893 PRODUCT DATA SHEET SUBSTRATES & SURFACE PREPARATION General Steel Concrete or CMU Non-Ferrous Metals Surfaces must be clean and dry. Employ adequate methods to remove dirt, dust, oil and all other contaminants that could interfere with adhesion of the coating. SSPC-SP6 with a 1.0-2.0 mil (25-50 microns) surface profile. When using under fireproofing products, defer to the primer surface preparation requirements in the product data sheet of the fireproofing product. Concrete must be cured 28 days at 75°F (24°C) and 50% relative humidity or equivalent. Prepare surfaces in accordance with ASTM D42582 Surface Cleaning of Concrete and ASTM D4259 Abrading Concrete. Voids in concrete may require surfacing. Surface profile should be a dense angular 1.5-3 mils and is best achieved through abrasive blasting in accordance with SSPC-SP16 for atmospheric exposure.

FAQs

What substrates can Carboguard® 893 be applied to?

It is intended for clean, dry surfaces including steel, concrete or CMU, and non-ferrous metals. Surface preparation must remove dirt, dust, oil, and contaminants that could interfere with adhesion.

How should surfaces be prepared before applying Carboguard® 893?

Steel requires SSPC-SP6 with a 1.0–2.0 mil (25–50 microns) surface profile. Concrete must be cured 28 days at 75°F (24°C) and 50% relative humidity or equivalent, and prepared following ASTM D42582 and ASTM D4259.

What are the recommended mixing, thinning, and pot life guidelines?

Power mix separately, then combine and power mix, and do not mix partial kits. For 1:1 ratio (A to B), pot life is 4 hours at 75°F (24°C) and ends when the coating loses body and begins to sag; higher temperatures shorten pot life.
