Development of phenol-urea-formaldehyde resins (PUF resins) by co-polymerisation to extend the range of applications in chip and fibre board production

Attempts to synthesize PUF adhesives were based on homogeneous and heterogeneous catalytic processes. The method developed is not considered prone to faults. The technical application of PUF adhesives in areas other than the timber sector, such as the rubber, glass and mineral wool sectors, seems possible.
