HIGH TEAR STRENGTH GLASS MAT UREA-FORMALDEHYDE RESINS FOR HYDROXYETHYL CELLULOSE WHITE WATER

摘要

HIGH TEAR STRENGTH GLASS MAT UREA-FORMALDEHYDE RESINS FOR HYDROXYETHYL CELLULOSE WHITE WATER A urea-formaldehyde resin modified with a water-insoluble anionic phosphate ester is used as binder in the preparation of glass fiber mats using a hydroxyethyl cellulose white water system. High tear strength glass fiber mats can be produced in a hydroxyethyl cellulose white water system using such a binder.
