    carboline 1340

    Carboline 1340 Clear is Epoxy-polyamide. Part A and Part B mixed prior to application

    GENERIC PROPERTIES :

    Penetrating clear primer-sealer for concrete surfaces prior to application of surfacers or polyurethane membranes. Carboline 1340 Clear meets ASTM C-309 Type 1 specification for moisture retention of concrete (check local Air Pollution Regulations before use). Excellent fast-drying material. Priming and sealing action provides excellent adhesion for surfacers and polyurethane membranes.

    RECOMMENDED USES :

    As a curing compound or form release agent. For application on “green” concrete walls to retard the escape of moisture during cure period. Excellent for use as a form coating on plywood or steel forms. Application prior to surfacing assures tight adhesion between concrete and surfacers or membranes. Compatibility with other coatings, surfacers and polyurethane membranes eliminates need for form release oils or curing oils.

    NOT RECOMMENDED FOR : Immersion in strong acids or solvents or in corrosive areas without recommended topcoat.

    SURFACE PREPARATION : Remove any oil grease from surface to be coated with clean rags soaked in Carboline Thinner #2 in accordance with SSPC-SP 1-82.
    Steel : For non-immersion service, abrasive blast to a Commercial Finish in accordance with SSPC-SP 6-85 to a degree of cleanliness in accordance with NACE #3 to obtain a 1-2 mil (25-50μ) blast profile.
    Concrete : Curing Compound-Walls Only : Apply immediately after forms have been stripped. Floors must have cured concrete. Carboline 1340 Clear cannot be used as a curing membrane for concrete floors. Form Release Compound: Use clean, dry, untreated Grade 1 plywood. Apply at least two coats, thin first coat 50%. Refresher coats may be applied as needed. Carboline 1340 Clear is not a substitute for blasting or acid etching for immersion service.

    NOTE : While Carboline 1340 Clear may be applied to green concrete walls, generally additional coats or other coatings should not be applied until the concrete has cured 28 days at 75℉(24℃) and 50% R.H. or equivalent.

    Primed surface – Remove fins and other protrusions by stoning, sanding or grinding. Remove form oils. incompatible curing agents and hardeners by abrasive blasting. For large holes or
    pits, use an epoxy surfacer for leveling and uniformity prior to application of Carboline 1340 Clear.

    Immersion Service – Abrasive blast to open all voids and obtain a surface similar to medium grit sandpaper (horizontal surfaces may be acid etched). Blow or vacuum off sand and dust. Non-immersion – Horizontal surfaces must be acid etched or abrasive blasted to remove laitance. For other surfaces, blow off with compressed air to remove dust.

    Wood : Should be free of chips and splinters. Excessively rough wood should be sanded before coating.

    MIXING : power mix separately, then combine and mix in the
    following proportions:

    Mfr. & Gun                                              2 Gal. Kit                              10 Gal. Kit
    Carboline 1340 ClearPart A                   1 gallon                                  5 gallons
    Carboline 1340 ClearPart B                   1 gallon                                  5 gallons

    For spray or brush application, may be thinned up to 25% by volume with Carboline Thinner #15. When coating wood, the first coat should be thinned 50% by volume with Carboline Thinner #15.

    Allow a 1 hour “sweat-in” prior to application.

    NOTE : Use of thinners other than those supplied or approved by Carboline may adversely affect product performance and void product warranty whether expressed or implied.

    POT LIFE : Twenty-four hours at 75℉ (24℃) and less at higher temperatures. Pot life ends when coating become too viscous to use.
