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