Making tissues and substrates waterproof or water repellent is an important activity for Finipur. Using various techniques, we can achieve or improve these characteristics for your product. We can test how water repellent or waterproof something is using what is known as the spray test. This is a sort of shower test to determine a material's resistance to surface moisture, using water. A sample of the material is stretched over a ring, and an amount of water is spotted on this material via a funnel. The final result, known as the spray class, is determined by the appearance of this sample in comparison with described standards and photos.
