Description Sikadur®-32 LP is a two-component, epoxy-based structural bonding agent designed for use in high-temperature environments. It is moisture-resistant and can effectively bond wet or dry materials to both damp and dry substrates. This product is ideal for use in hot and tropical climates. Applications Sikadur®-32 LP is intended for use by skilled professionals as a structural adhesive to bond fresh concrete to hardened concrete. Features Application temperature range: 20°C to 40°C Can be applied in thicknesses up to 1 mm Easy to mix and apply Suitable for both dry and damp concrete surfaces Excellent adhesion to a wide range of construction materials Cures without shrinkage Components are color-coded for easy mixing control No primer is required Provides both high initial and final mechanical strengths Impermeable to liquids and water vapor Certifications and Test Reports CE Marking and Declaration of Performance according to EN 1504-4 for structural bonding Product Information Composition: Epoxy resin with selected fillers Packaging Options: 1 kg ready-to-mix unit (Parts A B) 5 kg ready-to-mix unit (Parts A B) 25 kg ready-to-mix unit (Parts A B) (Refer to current price list for variations in packaging) Shelf Life: 24 months from the production date Storage Conditions: Store in original, unopened, and undamaged packaging in dry conditions at temperatures between 5°C and 30°C. Always follow packaging instructions. Color: Part A: White Part B: Dark grey Mixed (Parts A B): Concrete grey Density: Mixed resin ~1.4 ± 0.1 kg/l at 23°C Technical Information Compressive Strength (ASTM D 695-95) at different curing times and temperatures: 1 day at 23°C: ~2 N/mm² 3 days at 23°C: ~14 N/mm² 7 days at 23°C: ~34 N/mm² 14 days at 23°C: ~39 N/mm² 7 days at 40°C: ~41 N/mm² 14 days at 40°C: ~56 N/mm² Tensile Adhesion Strength (EN 1542): 7 days on dry concrete at 23°C: >3 N/mm² 7 days on moist concrete at 23°C: >3 N/mm² (100% concrete failure) Shear Adhesion Strength (ASTM C882/C882M-20): ≥10 N/mm² at 28 days Shrinkage: Cures without shrinkage Application Information Mixing Ratio: Part A : Part B = 2 : 1 by weight or volume Consumption: Approximately 1.3 kg/m² per mm of thickness (theoretical, surface porosity and variations may affect actual usage) Layer Thickness: Maximum 1 mm Sag Flow: Non-sag up to 1.0 mm thickness on vertical surfaces (EN 1799) Material Temperature: 20°C minimum / 40°C maximum Ambient Temperature: 20°C minimum / 40°C maximum Dew Point: Avoid condensation; ensure steel substrate temperature is at least 3°C above the dew point Substrate Temperature: 20°C minimum / 40°C maximum Substrate Moisture Content: Cementitious substrates should be dry or slightly damp (no standing water). For damp substrates, ensure thorough brushing of the adhesive. Pot Life At 20°C: Pot life ~145 minutes, open time ~270 minutes At 30°C: Pot life ~55 minutes, open time ~240 minutes At 40°C: Pot life ~35 minutes, open time ~120 minutes (EN ISO 9514) The pot life begins once Parts A and B are mixed. Pot life is shorter at higher temperatures and longer at lower temperatures. Larger quantities mixed together will result in a shorter pot life. To extend workability at higher temperatures, the mixed product can be divided into smaller portions, or the components can be chilled before mixing (but not below 5°C).
