Solvent-free architectural coatings made from plant materials for reduced air pollution and dependence on fossil fuels.
- A fully bio-based process for reduction in curing time and viscosity in drying oils
Ozonized lipids demonstrated up to a 70% reduction in curing time and viscosity. The functionality of these lipids can be used to tailor the properties of the dual use curing agents/reactive diluents.
- Bio-based nanotechnology to increase the adhesive strength of UV-cured coatings
Relaxation stresses during the near-instantaneous polymerization of UV-curable coatings significantly reduce their adhesive strength. With our award-winning technology for urethane-based photo-oligomers, unmodified cellulose nanocrystals (CNC) were shown to increase the by more than 150% in the model system. (publication)
- Visible light curing of epoxidized oil as a more durable and fast-curing alternative to drying oils
A drying oil analogue is being developed from epoxidized plant lipids to meet the demand for both sustainability and high performance. The lipids are minimally processed which allows fast cationic photopolymerization under visible light in the presence of plant pigments as photosensitizers.

Vinay Patel - PhD Candidate
MSc Industrial Chemistry (Oils, Fats & Waxes), SP University, India
MBA Troy University, Alabama, USA
Solvent-free, plant oil-based epoxy resins to complement phenol formaldehyde resins in natural fiber bio-composite, coating and adhesive applications.
- Synthesis of solvent-free, plant oil-based bio-resins. Synthesis of bio-based curing agent mixtures that are compatible with plant oil-based epoxides. These curing agents can eliminate the use of solvents in synthesized bio-resins.
- Use of epoxidized methyl esters as reactive diluents in the preparation of bio-resins. The viscosity of epoxides and curing agent mixtures are being reduced significantly while overall mechanical performance of bioresins improved.
- Patent pending: low temperature curable plant-oil based bio-resins. Novel, bio-based curing agent mixtures (patent pending) and plant oil-based epoxides are being cured at low temperatures to form bio-resins. These may be used for additional applications with existing ones where low temperature curable resins are being used.
- Additional research interests: lipid modifications and oleochemicals for food and industrial applications; oilseeds processing and oil refining: process optimization, quality control, and R&D.
