“…[12][13][14][15] The biobased materials are useful for UV-curing application. A great deal of research has been carried out on modification and application of biobased material for UV curing such as photoinitiated polymerization of epoxidized soyabean oil, 16,17 the cationic photopolymerization of epoxynorbornane linseed oils, 18 UV crosslinking of acrylated epoxidized linseed oil, acrylated epoxidized soybean oil, 19,20 UV-cured coatings of castor oil (CO) modified by acrylate, 6 and photo-curing of a pigmented UV-curable tung oil alkyd system. 21 The research is focused on the use of renewable material such as CO to synthesize reactive diluents for UV-curable urethane acrylate oligomers and examines its coatings properties.…”

Castor oil (CO)-based reactive diluent for UV-curable urethane acrylate oligomers was synthesized by the reaction of a CO with diethanolamine and the resultant product was subsequently reacted with allyl chloroformate. The reactive diluent was characterized by FTIR and 1 H NMR techniques. This reactive diluent was incorporated in a urethane acrylate oligomer and photoinitiator at different weight fractions varying from 5 to 25 wt% for UV curing. The effects of reactive diluent concentrations on the viscosity of the formulations along with mechanical, chemical, and optical properties of UV-curable coatings were studied. Furthermore, the cured films were evaluated for glass transition temperature (T g ) determined by differential scanning calorimetry and thermal stability by thermogravimetric analysis. Gel content and water absorption of UV-cured films were evaluated.

“…In recent years, bio‐based materials obtained from renewable resources have gained significant interest for an increasing number of applications . Castor oil (CO) is an inexpensive, environmentally friendly, renewable, and naturally occurring vegetable oil with low toxicity and free secondary hydroxyl groups . Castor oil has an overall hydroxyl functionality of about 2.7 .…”

Modification and use of natural products have gained a lot of interest in recent years due to their environmental friendliness and their availability from different sources. In this study, (castor oil)-based photo-curable highly hydrophobic coatings were prepared and characterized. Castor oil was first modified with 3-isocyanatopropyltriethoxysilane and then hydrolyzed prior to the coating preparation. The resulting precursor was mixed with norbornyl acrylate and hexanediol diacrylate, and highly roughened hydrophobic coatings were prepared with the aid of fluorinated/nonfluorinated alkoxysilane coupling agents and hydrophobic fumed nanosilica particles. The coatings were applied on borofloat glass. The addition of fluorine and nanosilica showed a significant impact on the properties of the coatings. As the fluorine and nanosilica contents were increased in the formulations, flame retardancy and the contact angle values of the coatings increased. The surface roughness of the coatings increased with the addition of hydrophobic fumed nanosilica particles. Also, the relation between the surface energy and the contact angle values of the coatings was investigated.
