ACRYLAMIDE
Category：Paint chemicals
Introduction
Our acrylamide aqueous solutions are produced by having acrylonitrile undergoing through hydration reaction. Our acrylamide solutions are extremely stable and have excellent quality. Polymeric and copolymeric products made from acrylamide are widely used for paper chemicals, coagulants, adhesives, petroleum engineering, agricultural engineering, civil construction, processing of leather, and metal coating.
