Modification of Alkyd with Epoxy and its Application for Paint Part 1: Epoxy Alkyd Ester Manufacturing and some Properties of Paint made from this Ester

Abstract

The article introduces the modification of alkyd resin by epoxy resin to make epoxy alkyd ester. The study investigated the effects of reflux xylene content, the proportion of the constituents participating in the esterification reaction on the reaction processing and acidity index of the product. The infrared (IR) spectroscopy results confirmed the formation of ester bonds after the reaction. The paper also studied the mechanical properties of paint film based on the synthesized ester epoxy alkyd and compared them with the alkyd paint, the results showed that impact resistance and hardness of the study sample were higher than those of the alkyd paint sample. In addition, investigation, comparison of thermal stability of alkyd paint and epoxy alkyd paint film were also mentioned.
 Keywords: Epoxy alkyd esters, mechanical properties, thermal endurance, drying time.

Aging of Environmentally Friendly Alkyd Coating Containing Tinuvin 292 under Effect of UV Radiation

“…Aging or degradation of paint or varnish coatings under weather factors such as UV radiation, humidity, oxygen, high temperature, etc. leads to the blistering, chalking, losing adhesion [1][2][3]. To reduce the aging of coatings exposed to UV radiation, many kinds of UV additives have been added in coatings [3][4][5].…”

Effect of Graphene Oxide on UV-Thermo-Humidity Degradation of Environmentally Friendly Alkyd Composite Coating

“…Alkyd paint is one of the most popular industrial paints. This can be used for many purposes, including indoor and outdoor [1,15,16]. In recent decades, environmentally friendly paints have been studied to reduce volatile components by using chitosan, lignin, starch, shellac, wool fibers, vegetable oils, etc., in paints or adding oil modified with silane-based diluents to alkyd paint [17][18][19][20][21].…”
