Effect of tackifier resin and non-rubber components on adhesive property of natural latex

Abstract

The objective of this study is to better understand the adhesive property of natural latex using phenolic resin at different ratios. Whole natural latex (WNL) and deproteinized natural latex (DPNL) are used. By increasing the resin ratio, the total solid contents (TSC) and viscosity for both types of latex increase. Interestingly, DPNL presents better adhesive properties than WNL for a given resin ratio. The phenolic resin at 3 phr gives the best adhesive property of latex. Beyond this resin ratio, the adhesive property decreases. Nevertheless, the phenolic resin can foster the flow properties in latex during the aging time, thus increasing the adhesive property of latex.
