Abstract

Abstract:

Urea formaldehyde resins were prepared in the laboratory using keratin through copolymerization reaction. Conventional Urea formaldehyde resins were also manufactured without the addition of keratin during the reaction. Through the determination of such reaction technology as molar ratio, adding a sequence of keratin and adding amount of keratin, we synthesized the low toxic urea resin. The resins were admixed with suitable hardener and the panels were made. Bond quality and formaldehyde content were evaluated. The results show that adding amount of 5 % keratin and adding keratin with the third feeding of urea is the best choice. From the studies, it was found that keratin addition reduces the formaldehyde content in the panel without affecting the strength properties.
