VANILLIN AS A BIO-BASED PHENOLIC CROSSLINKER FOR MELAMINE-FORMALDEHYDE COATINGS (RFT-520)
Scientists from North Dakota State University have utilized the vanillin that was derived from lignin as a bio-based cross-linker in melamine-formaldehyde coatings. Vanillin is first reacted with any acetoacetylated polyol via a Knoevenagel Condensation, allowing production of a wide range of intermediates that are suitable for crosslinking with MF resins. The resulting products would have numerous potential applications, including laminate flooring, cabinetry, surface coatings, textile finishes, and paper processing. The use of vanillin not only provides a bio-based alternative, but the resulting coatings were shown to provide increased impact resistance, hardness, and solvent resistance.
- Versatile approach to produce bio-based MF coatings
- Impact resistance, hardness, and solvent resistance may be optimized for a given application based on polyol selected for initial reaction
- Enables additional value-added use of lignin and its derivatives
- Applications in baking enamels for metal substrates such as container coatings, coil coatings, furniture, and fixtures
The technology includes resins and
coating compositions of melamine-formaldehyde resins that incorporate vanillin
from any source.
This technology is patent pending with fully preserved PCT patent rights and is available for licensing/partnering opportunities.
