Fluorine-Free Water Repellent | Manta WS370
Manta WS370 is a water-based, silicone-modified, fluorine-free water-repellent emulsion with a nanometer particle size, designed for durable water-repellent (DWR) finishing of textiles and leather. It is weakly cationic, easily diluted with water, and used on outdoor apparel, technical fabrics and leather; textile finishing is by padding followed by drying and curing.

- Translucent milky white liquid
Overview
Manta WS370 is a water-based, silicone-modified water-repellent emulsion with a nanometer particle size, designed for water-repellent finishing of textiles and leather. It is fluorine-free, supplied as a translucent milky white liquid with a pH of 4-7, and can be easily diluted with water and applied directly at room temperature.
In the textile padding process, WS370 is diluted with deionized water to a working concentration chosen for the specific fabric, and the treated fabric is then dried and cured. Adding a cross-linking agent to the finishing bath can further enhance both water-repellent performance and wash durability. The working concentration, cross-linker level and curing conditions are given in the TDS.
WS370 is designed for textiles and leather rather than building materials. It is weakly cationic, so test suitability before combining it with other textile additives, especially anionic auxiliaries. Manta WS400 is also a cationic emulsion, but it is a silane/polysiloxane product for impregnating porous mineral substrates.

- Leather: water-repellent leather treatments
Application Guidelines
1. Textile Padding Process:
Dilute Manta WS370 with deionized water to a working concentration of 30–80 g/L, depending on the specific fabric. Dry and cure the treated fabric at 150°C – 180°C for 0.5 to 3 minutes. If 6–10 g/L of a cross-linking agent is added to the finishing bath, it can further enhance both the water-repellent performance and wash durability.
