Epoxy Coatings Based on Modified Vegetable Oils for Wood Surface Protection against Fungal Degradation
The study describes the curing and thermal behavior of a new castor oil maleic anhydride adduct/epoxy oils/5–Bromosalicylic acid coatings and their composites with wood. The epoxidized oils were flax and hemp. The kinetic parameters of the curing and thermal degradation processes were calculated. Th...

| description | The study describes the curing and thermal behavior of a new castor oil maleic anhydride adduct/epoxy oils/5–Bromosalicylic acid coatings and their composites with wood. The epoxidized oils were flax and hemp. The kinetic parameters of the curing and thermal degradation processes were calculated. The resistance of the coated wood surfaces against Cladosporium cladosporioides, Aspergillus brasiliensis, and Penicillium chrysogenum was tested. Color changes, FT–IR and SEM were conducted before and after fungal attack. The decay resistance and color change of raw wood and wood treated samples against fungi was tested. Based on the color changes and according to ASTM D 2017, the decay resistance rating for covered samples was considered as “highly resistant”. Chemical resistance and coating performance tests were also undertaken. The obtained results recommend the described materials for applications in wood protective coatings. |
