Sikaflex 252 - Polyurethane construction adhesive 300ml

Sikaflex 252 - polyurethane construction adhesive

Sikaflex 252 is a flexible one-component polyurethane adhesive designed specifically for bonding large components in vehicle construction. Suitable for bonding coated metals, GRP laminates, ceramics and plastics.

Capacity : 300ml

POSSIBLE BULK PACKAGING:

• Carton - 12 pcs.

SCOPE OF APPLICATION

Sikaflex 252 is suitable for joints subject to dynamic stress. It is suitable for gluing wood, metals, especially aluminum (including anodized), steel sheets (including phosphated, chromated and galvanized), metal primers and paint coatings (2-component systems), ceramic materials and plastics.

Manufacturer's advice should be sought before use on plastics susceptible to stress cracking. This product is intended for experienced professional users only. Tests should be performed on actual substrates and conditions to ensure adhesion and material compatibility.

PRODUCT ADVANTAGES

• Bonds well to a wide range of substrates
• Capable of withstanding high dynamic stresses
• Good gap filling properties
• Paintable
• Vibration dampening
• Electrically non-conductive

CHEMICAL RESISTANCE

Sikaflex 252 is generally resistant to plain water, seawater, dilute acids and dilute alkaline solutions; temporarily resistant to fuels, mineral oils, vegetable and animal fats and oils; not resistant to organic acids, glycolic alcohol, concentrated mineral acids and corrosive alkaline solutions and solvents.

APPLICATION METHOD

Surface preparation

Surfaces must be clean, dry and free from grease, oil, dust and dirt. Additional surface preparation depends on the specific nature of the substrate and is crucial for long-term bonding. Suggestions for surface preparation can be found in the current edition of the appropriate Surface Preparation Guide. It should be taken into account that these suggestions are based on experience and must in each case be verified by tests on the original substrates.

App

Sikaflex 252 can be applied at temperatures between 10 °C and 35 °C (ambient and product), however changes in reactivity and application properties must be taken into account. The optimal temperature of the substrate and adhesive is between 15 °C and 25 °C.

Please note that the viscosity of the adhesive increases at low temperatures. For easier application, the adhesive should be conditioned at room temperature before use. To ensure uniform joint thickness, it is recommended to apply the adhesive in the form of a triangular path.

Smoothing and finishing

Smoothing must be done before the adhesive's open time expires. It is recommended to use Sika Tooling Agent N for smoothing. Other smoothing agents must be previously tested for suitability and compatibility.

Removal

Uncured Sikaflex 252 can be removed from tools and equipment with Sika Remover208 or another suitable solvent. Once hardened, the material can only be removed mechanically. Hands and exposed skin should be washed immediately using hand towels such as Sika Cleaner-350H or a suitable industrial hand cleaner and water. Do not use solvents on the skin.
