Bicast, Bycast, Pleather are the particle board of leather. While not exact, the ones we have been able to speak with the manufacturer on indicate ground leather, bound with a resin then a urethane coating. It is run through a platen to produce a 'grain'. When it splits (cut or weak spot) it frays. Both manufacture's brochures state it needs no conditioner, can be wiped off and is not repairable. We can debate all of these but primarily interested in redying sections. We see the type of color loss caused by alcohol (perfumes etc) and acetone (fingernail polish remover) Any thoughts on getting a good bite either mechanical by scuffing (400 and up) or chemical through an adhesion promoter? Also separate topcoats or mixed with the dye?
