If during this"colour change" process the existing and intact pigment finish is not sufficiently dissolved and/or sanded, the finish will not adhere properly, leading to the same colour separation as in the case of delamination.ĭelamination: A typical colour detachment in furniture leather. If, in the tannery the finish does not have the exact colour tone required by the customer, it has to be top finished again in the right tone, as it cannot be sold elsewhere. The phenomenon is also referred to as "delamination". It's a quality problem which shouldn’t occur on newer leather. Grease from perspiration can cause the paint to become unstable and sensitive, leading to the colour rubbing or peeling off.
Another problem is when the top colour layer is softened by contact with sweat or hair grease. This may be due to incompatible layers or a long break during the application of the finishing process. However, sometimes the bonding to the lower layer can be poor. Primer, colour and finish are sprayed on in rapid succession, so that the three layers stick together and become inseparable. Good leather is so well manufactured that colour separation cannot occur unexpectedly. There are many reasons why this happens but the main cause is a quality issue with the colouring process carried out during leather production. Initial signs of such colour separation can eventually lead to an entire layer peeling off. Typical use-related abrasions on car and furniture leathers.Ĭolour peeling off on furniture leather is a regularly-occurring problem. This colour layer can wear off with use, depending on the quality of the leather but it can also lead to unexpected color abrasion, color layer detachment or film detachment. It can also be applied with a roller or by glueing a coloured foil on top. Mostly the colour is sprayed onto the leather.
