Adhesion of UV-Curable Coatings to Beech Wood

Abstract:

In this paper, adhesion of solid coatings to wood is assessed through interactions among surface forces at their phase boundary. The issue is treated on an example of beech wood and a priming UV lacquer. Our approach used analogy with the laws valid for the system solid – liquid. The results show that cohesion of wood > adhesion of coating to wood > cohesion of coating. This relation was also confirmed by the testing of mechanical loading in tension of the whole system.
