By replacing commonly used formaldehyde-based resins with a new type of binder, researchers at UMaine have developed fiber board building material that is nontoxic, made entirely from renewable materials and is 25% stronger than currently available products. The new binder includes cellulose nanofibrils (CNF), which are wood fibers about 200 micrometers in length and 30 nanometers wide. The CNF is manufactured using a UMaine proprietary mechanical process that is free from harmful chemicals or additives.
- Reduction in health problems and related expenses (up to $48m per year 1) caused by formaldehyde exposure.
- Up to 25% increased product strength.
- All components, precursors and processing materials are renewable and nontoxic.
A stable, aqueous barrier coating composition includes: (a) prolamine; (b) cold water insoluble polymer; (c) water; (d) water-soluble co-solvent; and (e) stabilizer. The composition, when applied to a substrate, produces an article having a high surface energy and resistance to oil and grease penetration. A method of producing the article involves applying the composition to a substrate.
