Summary

The UV light cured polymeric materials, based on acrylic monomers, constitute a wide group of products with a complex chemical structure. The resins obtained from three leading manufacturers of polymeric materials used in wood industry: AkzoNobel, Klumpp and Kneho-Lacke were investi­gated. The chemical structure of the resins was characterized by infrared spectroscopy (IR). The obtained spectra revealed the presence of absorption bands which are characteristic for the structure of acry­lates as well as epoxides. The analysis of microstructure indicated the presence of significant amounts of fillers in the structure of tested resins. Our study showed that the AkzoNobel resin, characterized by the lowest viscosity, thermal stability, adhesion properties and hardness, contained the most amount offiller particles. The Klumpp resin was least susceptible to changes in the crosslinking conditions and showed the best adhesive properties. It was found, that the chemical structure influences the thermal and mechanical properties of the resins to a large rextent than the filler content.
