CCS Low Viscosity IR

CCS Low Viscosity IR – Injection Resin, Ultra Low Viscosity Structural Epoxy Adhesive

 CCS Low Viscosity IR is a two-component, solvent-free structural epoxy adhesive formulated for pressure injection and gravity feed applications. It is designed to penetrate and repair hairline cracks as fine as 2 mils (0.05 mm) in concrete, masonry, stone, wood, and CFRP. It is also used for anchoring bolts, dowels, and rebar, grouting under equipment, and external reinforcement bonding.

·         Part A (Resin): Clear amber

·         Part B (Hardener): Dark purple

·         Mixed Product: Dark purple epoxy adhesive

·         Mix Ratio: 2:1 by volume (100:43 by weight)

·         Available in kits (3, 15, and 150 gallons) and cartridges

·         Structural crack repair in concrete, masonry, and wood

·         Filling porous or honeycombed concrete

·         Anchoring bolts and reinforcement steel (e.g., dowels, rebar)

·         External reinforcement using steel plates or CFRP

·         Grouting tight voids and delaminations

·         Suitable for dry, damp, wet, or underwater conditions

·         Minimum Crack Width: 2 mils (0.05 mm)

·         Maximum Application Thickness: 1/4 inch (6.35 mm); for thicker sections, pre-fill with uniformly sized aggregate

·         Installation Temperature Range: Minimum 40°F (4.4°C); for other ranges, alternative ChemCo IR variants are recommended

·         Gel Time: 85 minutes at 40°F (4°C); 21 minutes at 73°F (23°C) for 100 g mass

·         Full Cure: 7 days at 73°F (23°C)

·         Pot Life: Not explicitly stated, inferred by gel time

·         Compressive Strength: 14,400 psi

·         Bond Strength (to wet concrete): 3,240 psi at 2 days; 3,330 psi at 14 days

·         Tensile Strength: 9,360 psi

·         Flexural Strength: 10,800 psi

·         Elongation at Break: 2.4%

·         Heat Deflection Temperature (HDT): 140°F (60°C) – maximum service temp should be 20°F below HDT

·         Viscosity: 200 cps mixed; increases to 1,150 cps at 40°F

·         Adhesion to Substrates: Strong bond to concrete, stone, masonry, wood, steel, and CFRP

·         Not UV resistant; no mention of UV stability after cure

·         Do not add solvents; thinning not permitted

·         Avoid use above 1/4” thickness unless aggregate is added to prevent thermal buildup

·         Excellent chemical resistance to a broad range of acids, bases, and industrial fluids, but limited resistance to hydrocarbon solvents

·         Surface prep must meet ICRI CSP 2 to CSP 4 for concrete and SSPC-SP 5/NACE No. 1 for steel

·         Recommended for professional application under ChemCo guidance

·         Storage: 3 years in unopened containers between 60–90°F (15.6–32.2°C), avoid freezing
