Abstract
The ability of a novel water-borne alkyd resin to penetrate the first and second order void volumes ofTilia americana L. andPinus strobus L. is documented. Penetration of the gross capillary system of both species is evidenced by the creation of high resolution, negative alkyd resin replicas of cell lumina, pit openings and cell wall surface detail. Infiltration of the transient cell wall capillaries present in saturated wood elements is demonstrated by the achievement of moderate antiswell efficiencies of up to 37 percent in small wafers of basswood and 27 percent in Eastern white pine wafers. The alkyd resin without metallic salt driers was present in the cell wall in a non-bonded, and therefore, leachable form. Cell type, character and frequency were found to influence antiswell efficiency and weight percent gain in both species. A low initial wood moisture content and a high resin solids content are requisite for achievement of greater dimensional stability.
