What is the mix ratio for Carboguard 60?

Carboguard 60 uses a 1:1 mix ratio by volume (Part A to Part B). Power mix each part separately before combining and power mixing again. Do not mix partial kits — the 1:1 ratio must be maintained for proper cure.

Can Carboguard 60 be applied over inorganic zinc primers?

Yes. Carboguard 60 may be applied over both organic and inorganic zinc rich primers. A mist coat may be required to minimize bubbling over zinc rich primers.

What is the pot life of Carboguard 60?

Carboguard 60 has a pot life of 4 hours at 75°F (24°C). Pot life shortens at higher temperatures. Pot life ends when the coating loses body and begins to sag.

Q: What is the coverage rate for Carboguard 60?

Carboguard 60 has 72% solids by volume. Theoretical coverage is approximately 231 ft²/gal at 5 mils DFT and 116 ft²/gal at 10 mils DFT. Coverage varies based on application method, surface profile, and film thickness chosen for the specific coating role.

Q: Does Carboguard 60 need a UV-stable topcoat?

Epoxies may lose gloss, discolor, and chalk when exposed to sunlight. For UV-exposed service where appearance matters, topcoat with a polyurethane, acrylic, alkyd, or compatible epoxy depending on exposure and need.

Q: What thinner should I use with Carboguard 60?

For spray application, use Carboline Thinner #2 up to 13 oz/gal (10%). For brush or roller, use Carboline Thinner #33 up to 15 oz/gal (12%). Thinner 236E may be used as an exempt thinner. Use of unauthorized thinners may void the warranty.

Carboguard 60 — Coverage Rates & Key Specs

DFT depends on the role: 4–6 mils per coat as primer or intermediate (without additives), 4–10 mils per coat (2 coats) direct-to-metal, or 8–12 mils per coat with optional Glass Flake (GF) or Micaceous Iron Oxide (MiO) additives. Do not exceed 10 mils in a single coat without additives.

Important Notes

⚠ Good to Know Before You Buy

DFT depends on the role. 4–6 mils as primer/intermediate, 4–10 mils per coat for 2-coat direct-to-metal, or 8–12 mils only with optional GF or MiO filler additives. Confirm your role before calculating gallons.
Mist coat may be required over zinc-rich primers. Applying directly over inorganic zinc can cause bubbling. Apply a thin mist coat first, allow to flash, then apply the full coat to minimize this risk.
Do not mix partial kits. The 1:1 (A:B) mix ratio is fixed. Partial kits will not cure correctly. Order a kit size that matches your usable application window.
4-hour pot life at 75°F — and shorter at higher temperatures. Mix only what you can apply in that window.
Cures down to 40°F standard, or down to 35°F (1.7°C) with Additive 8505 (sold separately). Below 50°F material temperature, allow a 15-minute sweat-in time before thinning.
Will chalk and lose gloss in direct sunlight. Like all epoxies, Carboguard 60 is not UV-stable. For exterior service where appearance matters, topcoat with an acrylic, alkyd, or polyurethane finish.
Surface tolerant. Steel may be prepared by SSPC-SP6 (1.5–3.0 mil profile) for most applications; previously painted surfaces require SSPC-SP2 or SP3.

Frequently Asked Questions — Carboguard® 60

What is the coverage rate for Carboguard 60?

Carboguard 60 is 72% solids by volume. Theoretical coverage is approximately 289 ft²/gal at 4 mils, 231 ft²/gal at 5 mils, and 116 ft²/gal at 10 mils DFT. For high-build maintenance applications at 8–12 mils with GF or MiO additives, use the lower coverage figures. Allow for application loss when ordering.

What is the mix ratio and pot life?

Mix ratio is 1:1 by volume (Part A to Part B). Pot life is 4 hours at 75°F. Power mix Part A separately, then Part B separately, then combine and power mix again. Allow a 15-minute sweat-in if material is below 70°F before thinning. Do not mix partial kits.

Do I need a mist coat over inorganic zinc primers?

A mist coat may be required to minimize bubbling over zinc rich primers (both organic and inorganic). Apply a thin mist coat, allow it to flash off, then apply the full coat at the target DFT.

Can I use Carboguard 60 as a standalone finish coat outdoors?

Carboguard 60 has a semi-gloss finish and can be used as a self-priming finish, but like all epoxies it may lose gloss, discolor, and chalk under prolonged UV exposure. For exterior service where appearance matters, topcoat with a polyurethane, acrylic, alkyd, or compatible epoxy depending on the exposure.

What substrates can Carboguard 60 be applied to?

Carboguard 60 adheres to steel (SSPC-SP6 with a 1.5–3.0 mil profile for most applications), concrete (cured 28 days, prepared per ASTM D4258/D4259), non-ferrous metals (SSPC-SP16 atmospheric, SP17 immersion), and previously painted surfaces (SSPC-SP2 or SP3).

What thinner should I use with Carboguard 60?

For spray, use Carboline Thinner #2 up to 13 oz/gal (10%). For brush or roller, use Carboline Thinner #33 up to 15 oz/gal (12%). Thinner 236E may be used as an exempt thinner. Use of unauthorized thinners may void the product warranty.

What is the recoat window for Carboguard 60?

Carboguard 60 has an extended maximum recoat window of 1 year at all listed cure temperatures (40°F to 90°F) — much longer than the 30-day recoat typical of most epoxies. If the maximum recoat time is exceeded, the surface must be abraded by brush-off blast cleaning or mechanical methods before applying additional coats.

Is Carboguard 60 suitable for immersion service?

Carboguard 60 is primarily formulated for atmospheric service and corrosion protection. For immersion or lining service, contact Carboline Technical Service to confirm suitability and system requirements for your specific environment.
