Sikadur 32 IN Epoxy Resin Bonding Agent

Product Description:

Sikadur 32 IN is a solvent-free, two-component epoxy resin bonding agent designed for structural applications. It provides a bond stronger than the tensile strength of concrete itself, making it ideal for bonding new concrete to existing concrete, mortar, and metals such as steel and iron.

Key Features:

• Solvent-Free: Safe for indoor use and environmentally friendly.

• Moisture Tolerant: Effective even on damp surfaces.

• Low Temperature Workability: Suitable for use in cooler climates.

• High Bond Strength: Ensures durable and reliable adhesion.

• Shrinkage-Free Curing: Maintains bond integrity during curing.

Technical Specifications:

• Chemical Base: Epoxy resin.

• Density (mixed): 1.55 ± 0.05 kg/L at +27°C.

• Shelf Life: 12 months from production date when stored in original, unopened packaging at temperatures between +5°C and +40°C.

• Storage Conditions: Store in dry conditions, away from direct sunlight.

Mechanical Properties:

• Compressive Strength: ≥15 N/mm² after 1 day; ≥40 N/mm² after 7 days at +30°C.

• Tensile Strength in Flexure: ≥30 N/mm² after 10 days at +30°C (EN 196).

• Tensile Strength: ≥18 N/mm² after 14 days at +30°C (ISO 527).

• Tensile Adhesion Strength: ≥10 N/mm² on dry concrete after 14 days at +30°C (ASTM C882).

• Shrinkage: Hardens without shrinkage.

Application Guidelines:

• Mixing Ratio: Part A : Part B = 2 : 1 by weight.

• Pot Life: Approximately 55 minutes at +27°C (100 g mass).

• Open Time: Approximately 55 minutes at +30°C (100 g mass).

• Consumption: 0.3 – 0.8 kg/m², depending on substrate condition.

Surface Preparation:

• Concrete and Mortar: Must be at least 28 days old, clean, dry, and free from contaminants such as oils, grease, and laitance.

• Steel: Should be cleaned to a standard similar to Sa 2.5 to remove rust and scale.

Mixing Instructions:

• Mix Part A and Part B thoroughly for at least 3 minutes using a slow-speed electric drill (max. 600 rpm) until the mixture is smooth and uniform in color.

• After initial mixing, transfer the mixture to a clean container and stir again for about 1 minute to minimize air entrapment.

Clean-Up:

• Clean all tools and equipment immediately after use with Sika Colma Cleaner. Hardened material can only be removed mechanically.

Packaging:

• Available in 3 kg pre-batched units (Part A: 2 kg, Part B: 1 kg).
