Epoxy Resin based Solventless and High Solid Coatings

Polyol from castor oil and epoxy resin for PU Coatings

Novel reactive polyols were synthesized via modification of castor oil, a renewable agricultural raw material with epoxy resin and triethylamine as a catalyst. This polyol was used for synthesis of polyurethane coating. Coating formulations were developed by reacting polyol with aromatic adduct, aliphatic adduct and castor oil based adduct in different NCO/OH ratio. All coating composition syst...

Effects of Colloidal Nanosilica on Epoxy-based Nanocomposite Coatings

Epoxy-based nanocomposites were fabricated with different content of colloidal silica nanoparticles such as 10.0, 20.0 and 30.0 wt %, through solution casting. The covalent bonding interfaces, resulting from a ring-opening reaction between silica nanoparticles and epoxy matrix were confirmed by the Fourier transform (FT-IR) infrared spectroscopy. These nanocomposites were characterized for ...

The Adsorption of an Epoxy Acrylate Resin on Aluminium Alloy Conversion Coatings

A thermodynamic study of the adsorption of an epoxy acrylate resin used for UV-cured coatings on two different anti corrosion pretreatments on aluminium alloys relevant to aerospace industry has been undertaken. Aluminium alloy Al2219 specimens, treated with an inorganic chromate based conversion coating (Alodine 1200S) and an organic titanium based conversion coating (Nabutan STI/310), were im...
