Investigation of the feasibility of using powder Coating for leather finishing

摘要

The feasibility of using powder coating technology, a process involving dry solid particulates, has been investigated for leather finishing for the first time. Results showed that powders can be applied to leather successfully using conventional electrostatic spraying facilities, provided that the leather is properly wetted with water. Powders can also be successfully applied to leather using non-electrostatic application methods, after pre-treating the leather surface with a tack agent, such as a soft resin, that makes the leather surface tacky and therefore receptive to powders.
