1 Testing Quilon water repellent 1955 E.I. du Pont de Nemours & Company (originator) Quilon chrome complex, a chemical that makes materials water repellent, was developed in DuPont's Industrial and Bio chemicals Department. It greatly increases the wet strength of paper and is also widely used in treating felt hats, shoe leather and garment suede. Garments of sheepskin suede treated with Quilon may be dry cleaned by ordinary methods, without special processing. Here a DuPont Chemist makes an experimental batch for test coatings.
