ABSTRACT:
Method of producing a paint or other plastic resinous material or product which on application to a surface imparts the surface with a tanned skin or leather-like appearance. The method includes incorporating into a paint or a plastic resin fluid a granular non-flocculating resin-plastic-compatible leather powder having a specific gravity of about 0.38 to about 0.5 g/cc. The leather powder is produced from tanned skin and/or leather chips and/or strips which have been steam heated a period of time sufficient to permit the chips and/or strips to swell and simultaneously cause the naturally occurring twisted and tangled collagen fibers therein to shrinkk and to automatically loosen and become less twisted and less tangled which upon pulverization produces a powder including relatively smooth granules having lubricity and relatively non-fibrous.
