IPIRTI has initiated a project to study and research on minimizing formaldehyde emission from panel products. The project namely “Amino adhesive blended with soya/tannin for panel products to minimize formaldehyde emission” under the supervision of Ms. Sujatha D, Scientist, IPIRTI has taken into account for study.
Since risks of emission of formaldehyde from pressed wood products are more where bonding agent is amino formaldehyde resin, many countries are putting restrictions on manufacture of such resin. Even where such resins are being manufactured and used for bonding wood, lot of care is being taken to minimize residual formaldehyde in the product otherwise finished products are being coated or overlaid to minimize emission of formaldehyde from the products.
Hence an approach to develop various amino resin systems by incorporating biomaterials or scavengers to minimize the formaldehyde emission level from plywood and particleboard to comply with the international standards is always continued. In this project, the renewable materials like soya and tannin will be explored to minimize the formaldehyde emission level from wood based panels.
The growing trend of offering less formaldehyde emission plywood and other wood panels would be benefited from this innovation. Similarly it will help to domestic furniture makers, who are looking for such types of panel products for making export grade furniture.
