Abstract
  This study provides an investigation of particleboard manufacture using tannin-ureaformaldehyde adhesive. Test board samples were made with regard to various replacementpercentage of tannin–urea (levels of 0, 10, 20 and 30%) and press time (12 and 15 min) andtheir properties were determined. Achieved ...  Read More

https://doi.org/10.22092/ijwpr.2012.109624

Abstract
  Tannins are the most desirable natural, renewable phenolic components which obtained from plant resources. The phenolic nature of tannins causes that this materials react with formaldehyde and form tannin-formaldehyde resins. In this study, the raw materials of wheat straw and forest woods were used ...  Read More
