Waterborne Coatings Based on Renewable Oil Resources: an Overview

Abstract

Polyurethane dispersions are gaining in importance due to their environmentally friendly coating system, versatile coating properties and ease of application. An enormous amount of research is focused on waterborne coatings such as waterborne alkyds, water-reducible alkyds, alkyd-acrylic hybrids, oil modified polyurethane dispersions and their composite latexes. This review gives a comprehensive compilation of recent studies on the synthesis and applications of waterborne coatings. The article specifically covers all of the research work carried out in the field of waterborne alkyd-acrylics, polyurethane dispersions and their hybrid latexes systematically.

Waterborne polyurethane dispersions synthesized from jatropha oil

“…Increasing concern on this issue has pressured the urethane industry to move toward water based systems. Waterborne polyurethane (PU) dispersion is a recent class of binder that is easily diluted with water and air-dried, stoved or crosslinked to produce volatile organic component (VOC) compliant coatings (Athawale and Nimbalkar, 2011). As with their solvent based counterparts, waterborne PU dispersions find application mainly in the ink, surface coating and adhesive industries.…”

Effect of surface modified TiO2 nanoparticles on thermal, barrier and mechanical properties of long oil alkyd resin-based coatings

“…Alkyd resins based on non-toxic, biodegradable, multifunctional, low cost, physically and chemically stable and eco-friendly renewable resources such as vegetable oils show properties comparable with properties of products based on petroleum, and therefore have found their industrial application in paints and surface coatings [5][6][7][8][9][10][11][12][13][14][15][16][17][18][19]. Especially interesting low cost vegetable oil is soy bean oil, which has balanced composition of unsaturated and saturated fatty acids and it can reduce yellowing and oxidative degradation of resin [2,[16][17][18][19].…”

Renewable resources in corrosion resistance

“…Such an approach can be employed on renewable resources in corrosion. In another review by Nimbalkar and Athawale, they have elaborated the use of VO in WB coatings (Athawale & Nimbalkar, 2011). In another excellent report, use of plant extracts as natural corrosion inhibitors has been briefly described (Raja & Sethuraman, 2008).…”
