Carboline Carbocoat 115 is a fast-drying steel primer that provides corrosion protection on structural steel. Well suited for fabrication shops that need fast cure to dry and handle times. May be top-coated with conventional alkyds or acrylics for colour, aesthetics or additional protection.
When applying a topcoat, Carboline Carbocoat 115 may be coated with Acrylics or Alkyds depending on exposure and need.

These times are based on a 1.5 mil (35 microns) dry film thickness. Higher film thickness, insufficient ventilation, high humidity or cooler temperatures will require longer cure times and could result in solvent entrapment or premature failure. *Dry to topcoat with itself or other alkyds.
Recoat intervals may vary from those listed above when using under intumescent fireproofing products. Consult Carboline Technical Service for recommended cure times before applying Carboline intumescent products.
Surface Preparation
General
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.
Steel
SSPC-SP6 with a 1.0-2.0 mil (25-50 microns) surface profile for maximum protection. SSPC-SP2 or SP3 as minimum requirement.
When using under fireproofing products, defer to the primer surface preparation requirements in the product data sheet of the fireproofing product

This product simply requires the substrate temperature to be above the dew point.
Condensation due to substrate temperatures below the dew point can cause flash rusting on prepared steel and interfere with proper adhesion to the substrate.
Special application techniques may be required above or below normal application conditions.
