Sikaflex® -Pro 3WF is a flexible, one-component sealant based on polyurethane with high mechanical and chemical resistance, and permissible movement capacity of up to 25 percent. When react with moisture in the air, it turns into an efficient elastic sealant providing excellent adhesion to most construction materials. In addition, it is resistant to water, seawater, diluted alkalis, cement slurry, and water dispersed detergent. It is packaged as foil pack, 20 foil packs per box, and contained approximately 600 milliliters of Sikaflex® -Pro 3WF. It has a shelf life of up to 12 months from the date of production in undamaged, original, and sealed packaging. It is advised to store Sikaflex® -Pro 3WF in dry conditions, protected from direct sunlight and at a temperature between +5°C and +25°C.
Sikaflex® -Pro 3WF is designed for sealing movement and connection joints in floors, pedestrian and traffic area, warehouses and production areas, applications in the food industry, sewage treatment plants, tunnel construction, and cleanroom. It is recommended to use only closed cell, sealant compatible foam backer rods, and the usage depth of the joint can be limited as radius should be approximately 20 percent bigger than the width of the joint. Furthermore, it is advised to use blunt implements to avoid damage of the surface and penetration of gases into the sealant. In addition, additional protection against water pressure is advised, such as extra backfilling of the joint space behind the backfilling material – e.g. with expanded polystyrene, is strongly recommended.
The bond areas must be of sufficient strength, dense, dry and free of fat and dust. In combination with Sika-Primer 3 mat damp concrete is acceptable. It is advised to clean the expected joint to be filled and ensure that all friable particles and contaminations are removed. Concrete should normally be prepared with an angle grinder.
For application instruction, Sikaflex® PRO-3 WF should be caulked into the joints in such a way, that no air is entrapped. It is recommended that the temperature on the surface of the adjacent building components must be measured before applying the product at an early stage. Furthermore, detergents and soap are not recommended as they may reduce the product chemical resistance and could lead to damages in a later stage.
It should be noticed that Sikaflex® -Pro 3WF contains Isocyanate, a harmful chemical which can be dangerous if come in contact with human skin. If accidental contact with the skin, rinse with plenty of water and soap. In addition, rinse with plenty of water and consult a doctor if in contact with eyes.
For safety precautions, it is advised to use proper protective equipment when handling and using the product. It should not be disposed into the drainage system or nearby water sources and soil, properly dispose of this product according to local laws and regulations.
