Texfin® C6-D - High performance, C6 durable water and oil repellent
Technical Properties
Texfin® C6-D is a premium fluorocarbon based on C6 technology for high quality finishing of cellulosic and synthetic performance textiles to impart durable oil, water and stain repellency.
Texfin® C6-D is capable of sustaining high oil and water repellency results after successive washes (up to 50 washes depending upon the substrate); it is important to tumble dry or hot press to reactivate the chemical after each wash cycle.
Texfin® C6-D is PFOS and PFOA* free (* below detectable limits) thus minimising the environmental impact whilst maintaining the performance compared to C8 polymer products.
Illustration
The results of a study conducted against a current, premium grade C8 based fluoropolymer illustrates the high technical performance that can be achieved with Texfin® C6-D (Both products were applied at the same add-on level). The results can be seen below. The Substrate tested was 100% woven cotton and was tested for durability for up to 15 washes with very little reduction in performance.
Application
To achieve maximum performances, substrates are required to be free from surfactants / salts and are neutral prior to finishing.
Application levels will vary from substrate to substrate and preliminary trials are recommended to determine optimum levels, however the following figures should provide a suitable starting point.
| 100% Cotton | 30-100g/l at approx 80 % p/u |
| Polyester/Cotton | 20-70g/l at approx 80 % p/u |
| Nylon & Polyester | 15-80g/l at approx 80 % p/u |
Typical dry and cure conditions are 160°C for 1 – 2 minutes
