Product Introduction

Application
Printing coating agents, adhesive tackifier, printing ink, paint, synthetic leather and PVC leather to enhance the adhesive viscosity.

Introduction
Though chloroprene rubber has an excellent weathering, oil and chemical resistance, it is necessary, in practice, to make use of a modifying agent to improve the properties of chloroprene rubber adhesive, such as tackiness retention time, phasing stability, heat resistance and adhesion strength. Alkyl phenolic resin for adhesive“APU-20-58G” is excellently compatible with chloroprene rubber and an indispensable modifying agent for chloroprene rubber for manufacturing adhesive to meet specific purposes.
