Effect of aqueous polymer treatments on wood properties. Part 1: Treatability and dimensional stability
IRG/WP 3610Z Ashaari, H M Barnes, R C Vasishth, D D Nicholas, D E Lyon
Partially air-dried sapwood of sweetgum (Liquidambar styraciflua) and southern pine (Pinus spp.) was treated with either aqueous polyacrylate or aqueous dimethyloldihydroxyethyleneurea (DMDHEU) solutions. Tests for dimensional stability were conducted on matched treated and untreated pieces. Measurement of the antishrink efficiency indicated that DMDHEU was a better stabilizer than the polyacrylate system. Stability was related to polymer retention and curing temperature.
