    Alkyl Phenolic Resin (APU-20-52G)

     

    Advantage

    • Softening point (Ring & Ball): 115-130℃
    • Appearance: pale yellow lump
    • Enhance the adhesion strength
    • Increase the phasing stability
    • Increase the heat resistance
    • Improve the tackiness retention time

     

     

    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. "APU-20-52G" is excellently compatible with chloroprene rubber and an indispensable modifying agent for chloroprene rubber for manufacturing adhesive to meet specific purposes.
