COUPSYL® SWRS by Couple Shimi Sepahan is a solvent-based silane–siloxane water repellent designed for waterproofing wood, building surfaces, and glass. It deeply penetrates materials to form chemical bonds that make them hydrophobic, protecting against water, contaminants, and ions. The product enhances durability, reduces staining, and improves paint appearance without needing an extra coating.
Completely absorbent and without creating films and layers
Very convenient high speed execution
Increase the life of wood products
Water repellency of raw wood surfaces
Hydrophobic wood and MDF surfaces
Water repellent silane–siloxane COUPSYL® SWRS must be diluted with solvent before use in a volume ratio of 1 to 6. Then apply to the surface with a pistol or brush and roller. (Refer to the product instruction file for more information)
Store in the main container and sealed in a dry and low light environment at a temperature of 15-40 degrees Celsius. In case of contact with skin, this product should be washed immediately with water. And see a doctor if swallowed. This solution contains volatile and flammable materials.
The COUPSYL® SWRS Water repellent product of solvent-based is offered in 1, 4 and 20 liter containers. Due to the absorption of ambient moisture by this material, this product must be stored in the main container as a seal.
Waterproofing all types of building surfaces
Fully absorbent and non–film forming
High durability and longevity
Improve and increase the surface color shade
Due to the hydrophobicity of the surfaces on which silane–siloxane COUPSYL® SWRS has been applied, it is not possible to apply water-based coatings.

COUPSYL® SWRS is a solvent-based silane–siloxane water repellent designed for waterproofing wood, building surfaces, stone, and glass. It deeply penetrates the substrate and forms chemical bonds, creating long-lasting hydrophobic protection. This improves durability, prevents water absorption, reduces staining, and enhances the appearance of surfaces without forming any visible film or layer.
Before use, COUPSYL® SWRS must be diluted with an appropriate solvent at a 1:6 volume ratio. It can be applied using a spray gun, brush, or roller. Surfaces should be clean and dry before application. Detailed instructions are available in the product usage guide. Proper ventilation is recommended during application due to the presence of volatile and flammable components.
Because COUPSYL® SWRS creates a highly hydrophobic surface, water-based coatings cannot be applied afterward. It also contains flammable solvents, so it should be kept away from heat and open flames. If it comes into contact with skin, wash immediately with water; if swallowed, seek medical attention. Store the product sealed in its original container in a cool, dry, low-light environment at 15–40°C.
