Resumen

OCAMPO, David; AGUIRRE, Elkin D; OSORIO, Alexander  y  RIOS, Luis A. WOOD COATINGS AND SEALANTS FROM ALKID RESINS OBTAINED FROM CASTOR OIL, PALM OIL AND USED FRYING OIL. Inf. tecnol. [online]. 2014, vol.25, n.2, pp.157-164. ISSN 0718-0764.  http://dx.doi.org/10.4067/S0718-07642014000200018.

Results on the development of new coatings and sealants for wood based on alkyd resins are presented. Indigenous castor and palm oils as well as used cooking oils were used to replace imported soybean oil in the synthesis of the resins. The products developed were characterized in terms of brightness, viscosity, adhesion to the substrate, thermal stability and drying times, under international and national standards, in order to determine similarity or changes with respect to commercial dupes. Is results indicate the possible inclusion of such raw materials, indigenous to the region, as an alternative for reducing costs, generating direct and indirect jobs and the incorporation of these vegetable oils of low commercial value in the production chain of wood coatings. Besides, added value is given to recovered frying oils by making them raw materials of commercial interest and minimizing their environmental impact on water ecosystems.

Palabras clave : alkyd resins; palm oil; castor oil; used frying oil; coatings; sealants; wood.
