KEMKO 064 HB

Grouts - Control Joint Filler And Embedded Wire And Can Light Sealer

KEMKO 064 HB – Control Joint Filler, Embedded Wire and Light Can Sealant

 KEMKO 064 HB is a two-component, high-viscosity, semi-rigid epoxy designed for sealing control joints, saw cuts, and embedding wires and can lights in concrete and asphalt surfaces. It is formulated specifically for high-build, single-pour applications and is ideal for both interior and exterior environments subject to impact and chemical exposure.

·      Part A (Resin) and Part B (Hardener) mixed in a 1:1 volume ratio (100:86 by weight).

·      Can be extended with aggregate (up to 2 parts aggregate per 1 part epoxy) for patching or larger fill volumes.

·      Designed to be placed using the KEMKO Model C Slot Pump or equivalent dispensing equipment.

·      Compatible with backer rods (optional).

·      Not to be mixed with solvents; faster curing may be achieved using KEMKO 008 SP.

·      Filling control joints and saw cut slots in concrete and asphalt.

·      Encasing embedded wires and steel can light fixtures (meets FAA P-606).

·      Loop grouting for stop lights and robotic induction systems.

·      Bonding precast and extruded curbs to concrete or asphalt.

·      Use in facilities with exposure to aircraft, forklift, or automotive fluids.

·      Suitable for sloped and uneven surfaces due to controlled flow properties.

·      Pot Life: 12–15 minutes (depending on volume).

·      Cure Time: Tack-free in 4 hours, hard dry in 6 hours (at 73°F/23°C).

·      Recommended Substrate Temperature: Minimum 50°F (10°C) during installation and cure.

·      Viscosity (mixed): 190 poise.

·      Tensile Strength: 1,400 psi | Elongation: 60% | Hardness: Shore D 62.

·      Bond Strength to Concrete: 400 psi.

·      UV Stability: Does not embrittle under sunlight; functionally UV resistant.

·      Color Options: Standard blue-gray or black; custom colors available.

·      Coverage (per gallon) varies by slot dimensions. For example:

o   1/4" x 1/4" joint = 300 linear ft/gal

o   1/2" x 1/2" slot = 75 linear ft/gal.

·      Does not contain silica fillers or VOCs, making it environmentally safer post-cure.

·      Excellent chemical resistance to acids, bases, fuels, oils, and deicing chemicals (limited resistance to hydrocarbon solvents).

·      Not recommended for use in freezing conditions or plastic concrete with unknown admixture compatibility.

·      Shelf life is 3 years in original sealed containers stored between 50–90°F.

·      For optimal results, surfaces should be CSP 2 to 4 (per ICRI 310.2R), and cleaned to white metal for steel (SSPC-SP5/NACE No.1).

·      Ideal for professional use with proper safety precautions and mixing tools (Jiffy mixer at 350–750 RPM).
