Crocking has long been a problem for denim producers, especially in recent years. PermaPel® SRZ6010 has been developed as a surface treatment to provide crock resistance to prevent the transfer of color onto fabric surfaces. It is a pre-crosslinked emulsion polymer that is water repellent and wash durable. It can be applied by various techniques including spraying, brushing, or coating and then dewatered to achieve results.
