Urethane-Modified Boron Containing Polyesteramide of Phthalic Acid from Jatropha Curcas Seed Oil

Abstract

Boron containing polyesteramide synthesized from Jatropha curcas seed oil, a renewable, non-edible and abundantly available resource has been found to show improved performances as coating materials. However, curing of the resins at elevated temperature restrict its viability in many service conditions, especially where baking are not possible. With a view towards the use of boron containing polyesteramide derived from Jatropha curcas seed oil and to cure at ambient temperature, toluylene diisocyanate (TDI) was incorporated in the resin in varying proportion to obtain urethane modified boron containing polyesteramide resins. The latter resins were found to cure at room temperature. The effects of amount of TDI on the drying time were also investigated. The synthesized resins characterized by physicochemical and spectral analyses. The film properties of the ambient cured urethane-modified boron containing polyestramides were also studied.

Coatings resins synthesized from oil-based precursors- A review

“…The oil used for making PEA can also be varied. 42,43 The changes in the properties are significant, and mainly, the anti-corrosive and antimicrobial properties are improved along with others like physio-mechanical, curing temperature, etc. 23,[26][27][28][29][30]44,45 Its usage in polymeric surface coating application is fostered by the desirable impact strength, abrasion resistance, gloss, scratch hardness, adhesion strength, and mechanical properties.…”
