- Viscoelastic thermal compression (VTC) is an excellent method for improving the physical properties of low density woods, but it has little effect on resistance to microbial degradation. The potential for improving durability through pre-impregnation with either phenol formaldehyde resin (PF) or tung oil was investigated in laboratory tests. Tung oil had little effect on decay resistance; while PF resins markedly improved durability against both white and brown rot fungi. The results suggest that resin pre-treatment was compatible with the VTC process and produced markedly more durable materials.
