## Frequently asked questions

Can you provide a water repellent?

Our technology is not based solely on water repellents. The process is very important, of course, as is the water repellent. For this reason, we do not provide water repellents by themselves.

Which are the corresponding fibers?

Nylon or polyester.

Other fibers can also be treated with DWR, but due to incompatibility with water repellents, the performance described on the website may not be achieved.

I would like to apply DANSUI coating to my new wear.

New outdoor wear is originally DWRed, so unless you are dissatisfied with the initial DWR, we recommend that you take it out when you feel that the DWR has decreased after several uses, as the effect of applying a top coat at additional cost is small.

Which brands have processing experience?

Billabong  
canadagoose  
COSBY  
DAIWA  
DESCENTE  
GOLDWIN  
HELLY HANSEN
