Résumé : |
Previous research results involving sulfur accumulation on cross sections of wood coated with latex paint led us to investigate whether acidic conditions could affect the bonding strength of paint and be a factor in catastrophic paint peeling. Through simulation of acidic dew under outdoor conditions, the study reported herein determined the effect of acid rain and/or dew on painted wood siding. Painted wood was soaked before dawn in various acid solutions for two hours each day, then exposed outdoors for the remainder of the day and night during the summer near Madison, WI. From October to May, the specimens were exposed but not soaked. After four years of exposure to weather and acid, only the painted wood interface for specimens soaked in sulfurous acid at pH 2 indicated deterioration as measured by fracture toughness testing. |
