TENSILE STRESS OF COATING FILMS

The aim of this contribution is the investigation the influence of the coating formulation on physical – mechanical properties especially on the hardness of finished surfaces, the adhesion of films of lacquers to wooden substrates, the resistance of finished surface to impact, the resistance of finished surfaces to mechanical demage - the impact tests. Tensile tests on free films have been messurend tensile stress. There were ivestigated transparent nitrocellulose, polyuretanne and UV curing high solid acrylic lacquers.The results showed confirmed the raltion between elastic modulus and strain at break on physical-mechanical properties of finished surfaces.
