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. Allow a 15-minute sweat-in time before thinning if material is below 70°F. 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.

What are the dry to recoat and dry to handle times for Carboguard 60?

Based on 5.0 mil DFT at 50% RH: at 40°F — Dry to Touch 3 hrs, Dry to Handle/Recoat w/ Itself 30 hrs, Dry to Topcoat 48 hrs. At 75°F — 45 min touch, 5 hrs recoat, 7 hrs topcoat. At 90°F — 30 min touch, 3 hrs recoat, 4 hrs topcoat. Maximum recoat time is 1 year at all temperatures.

Application Conditions

Condition	Material	Surface	Ambient	Humidity
Minimum	50°F (10°C)	40°F (4°C)	40°F (4°C)	0%
Maximum	90°F (32°C)	140°F (60°C)	120°F (49°C)	85%

Substrate temperature must be above the dew point. Condensation below the dew point causes flash rusting on prepared steel and interferes with adhesion. Excessive humidity or condensation during curing can cause discoloration and surface haze — any haze or blush must be removed by water washing before recoating.

Cold-weather application: Carboline Additive 8505 aids film forming down to 35°F (1.7°C). Add at 4 oz per mixed 2-gallon kit or 20 oz per mixed 10-gallon kit. Allow 15-minute sweat-in before thinning if below 70°F, and 24-hour cure before topcoating at surface temps down to 40°F. Additive 8505 will accelerate cure and reduce pot life.

Curing Schedule

Based on 5.0 mil (125 micron) DFT at 50% RH. Higher film thickness, insufficient ventilation, or cooler temperatures will require longer cure times.

Surface Temp.	Dry to Touch	Dry to Handle / Recoat w/ Itself	Dry to Topcoat w/ Other Finishes	Max Recoat Time
40°F (4°C)	3 Hours	30 Hours	48 Hours	1 Year
50°F (10°C)	2 Hours	20 Hours	24 Hours	1 Year
60°F (16°C)	1 Hour	8 Hours	10 Hours	1 Year
75°F (24°C)	45 Minutes	5 Hours	7 Hours	1 Year
90°F (32°C)	30 Minutes	3 Hours	4 Hours	1 Year

Max recoat exceeded: If the 1-year maximum is exceeded, abrade by brush-off blast cleaning or mechanical methods before applying additional coats.

Under intumescent fireproofing: Recoat intervals may vary. Consult Carboline Technical Service before applying Carboline intumescent products.

Force curing: Contact Carboline Technical Service for specific requirements.

Surface Preparation by Substrate

All surfaces must be clean and dry. Remove all dirt, dust, oil, and contaminants before application.

Substrate	Preparation Requirement

Good to Know Before You Buy

⚠️ Critical Notes

DFT determines how many gallons you need — and which system applies. 4–6 mils as primer or intermediate coat (no additives); 4–10 mils per coat in a 2-coat direct-to-metal system; 8–12 mils per coat only with GF or MiO additive. Do not exceed 10 mils in a single coat without additives. Confirm the role in your system before calculating material quantities.
Both Part A and Part B have flash points below 90°F — treat as flammable at ambient temperature. Part A flashes at 82°F (27.8°C) and Part B at 71°F (21.7°C). Keep away from sparks, open flames, and ignition sources during storage, mixing, and application. Use adequate ventilation; in enclosed areas, prevent vapor concentration from reaching the lower explosion limit.
Do not mix partial kits. 4-hour pot life at 75°F. The 1:1 mix ratio is fixed — partial kits will not cure correctly. Mix only what you can apply within the pot life window, which shortens at higher temperatures. If material is below 70°F, allow a 15-minute sweat-in 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. A mist coat may also be required over zinc-rich primers to prevent bubbling — apply thin, allow to flash, then apply the full coat.
