This product is ideal for both internal and external joints, offering excellent adhesion and resistance to harsh conditions, guaranteeing long-lasting performance in any project.

You can find this product in the Chemicals section, under Adhesives and Sealants.

FEATURES of Blinker polyurethane adhesive

• Single-component polyurethane sealant that cures quickly upon contact with atmospheric moisture.

• Contains reactive isocyanates and small amounts of solvent; it is recommended to work in well-ventilated areas and use protective gloves.

• Easy application with a manual gun.

• Excellent adhesion on a wide range of construction materials.

• Fast curing without shrinkage, ensuring precise and secure sealing.

• High chemical and mechanical resistance, ideal for demanding applications.

• Paintable once cured, allowing for perfect aesthetic finishes.

APPLICATIONS of Blinker polyurethane sealant

This adhesive is an excellent sealant for internal and external joints on a wide variety of materials such as concrete, cement, stone, wood, metals, ceramics, tiles, panels, partitions, glazed surfaces, and plastics. It is especially recommended as:

• Joint sealant in buildings and maintenance.

• Vehicle body sealant.

• Sealant for heavy and light prefabricated structures.

• Adhesive for industrial flooring, walls, and ceilings applications.

HOW TO USE:

1. Ensure surfaces are clean, dry, and free of dust or grease.

2. Degrease surfaces if necessary for better adhesion (use an appropriate cleaning solvent).

3. Ambient temperature should be between 5 ºC and 35 ºC; product temperature should not be below 10 ºC to avoid extrusion problems.

4. If needed, warm cartridges in a water bath at 15 ºC to 20 ºC.

5. Pierce the cartridge membrane and screw on the nozzle, cutting it to the desired bead size.

6. Apply the sealant with an extrusion gun and smooth with a spatula moistened with water and a little detergent.

7. For construction joints with movement, check that dimensional proportions are correct.
