KEMKO 026 UW IR

Epoxy Adhesive for Underwater Pressure Injection Grouting

 KEMKO 026 UW IR is a two-component, solvent-free epoxy resin system formulated for structural repair in submerged or underwater conditions. It is primarily used for pressure injection grouting in concrete, masonry, stone, steel, and wood structures in both fresh and salt water environments. Its applications include repairing cracks and delaminations, filling porous concrete, adhesive bonding of reinforcement plates, and anchoring hardware into various substrates.

 This epoxy system consists of Part A (epoxy resin, clear amber) and Part B (epoxy hardener, dark purple) mixed in a 2:1 ratio by volume. The mixed material results in a dark purple color. It is designed for use exclusively with the KIP System—an automatic meter, mix, and dispense equipment setup provided through licensed applicators.

 KEMKO 026 UW IR is suitable for structural repairs involving cracks, voids, delaminations, and annular space filling in underwater piling applications. It can be used in widths up to 1/4 inch directly, and for wider applications, pre-placed aggregate is recommended.

·      Minimum Substrate Temperature: 35°F

·      Installation Equipment: KIP System automatic mixer and dispenser

·      Substrate Conditions: Suitable for dry, damp, wet, immersed, or submerged surfaces

·      Thickness Limit: Direct application up to 1/4 inch; greater thickness requires pre-placed aggregate

·      Mix Ratio: 2:1 by volume (Part A : Part B)

·      Gel Time: ~15 minutes at 73°F; 50 minutes at 40°F

·      Curing Schedule: Achieves bond strengths of 2430 psi after 2 days and 2770 psi after 14 days at 40°F

·      Environmental Limits: Do not install at substrate temperatures below 35°F. For long-term bonding under shear stress, service temperature should not exceed 20°F below the material's heat deflection temperature (135°F).

·      UV Resistance: Not specified as UV stable or resistant; primary use is underwater, so UV exposure is minimal.

·      VOC Content: Zero VOC, solvent-free formulation

·      Chemical Resistance: Excellent resistance to acids, bases, fuels, and oils; limited resistance to hydrocarbon solvents

·      Shelf Life: Minimum of 3 years in unopened containers stored between 60–90°F

·      Handling: Part A and B have significant health hazards and must be handled with appropriate personal protective equipment.
