Leather finishing is chiefly affected, and enforcements of these regulations will make the use of finishes based on organic solvents more difficult in the future. Likewise the use of formaldehyde has to be reduced considerably due to its strong irritating effect on the mucus membranes. Today,we can manage to produce solventfree finishes and finishes based on protein which possess good physical properties,wet and dry.By the use of carefully selected binders,topcoating agents based on acrylics and urethanes,and crosslinkers it is possible to develop "high performance" finishes.The emission of V.O.C.'s can also be reduced to a large degree by using new application methods,such as rollcoating.

Water borne finishes - current problems and proposed solutions / Helmut Will in JOURNAL OF THE AMERICAN LEATHER CHEMISTS ASSOCIATION (JALCA), Vol. LXXXX, N° 1 (01/1995)  

[article]  inJOURNAL OF THE AMERICAN LEATHER CHEMISTS ASSOCIATION (JALCA) > Vol. LXXXX, N° 1 (01/1995) . - p. 1-12 Titre : Water borne finishes - current problems and proposed solutions Type de document : texte imprimé Auteurs : Helmut Will, Auteur ; P. Weyland, Auteur Année de publication : 1995 Article en page(s) : p. 1-12 Note générale : Bibliogr. Langues : Américain (ame) Index. décimale : 675 Technologie du cuir et de la fourrure Résumé : Water borne finishes are used nowadays for producting leathers that can meet up to the highest quality and physical requirements. The study deals with effects that can lead to problems in aquepis finishing. Especially, various kinds of grey effects are briefly describes and classified, followed by the attempt to analyze the causes.Some ideas are discussed as to how these problems can be avoided or overcome. The suscespibility of finishes to these effects in relation to changes in the formulation is shown in the results of a trial series.
