Acrylic Soft Binder

Introduction

Acrylic soft binder has been in use in leather finishing formulation especially for soft upper leathers. The process for preparation of this binder involves co-polymerisation of acrylic esters and vinyl monomers in presence of catalysts in order to obtain the required chain length and degree of polymerisation. The uniqueness of the binder is its improved functional properties. It forms a soft, firmly adhering and stretch film on leather with good fastness properties and cold crack as well as scuff resistance. The film is resistant to swelling. The binder does not load the grain, thereby retaining the natural look and feel of leather.
