The DryVac 1010 has been specially developed to meet the requirements of the millwork manufacturer. It is easy to apply and does not contain ingredients that cause a reaction with employees who may have sensitive skin or eyes. The product is readily applied by spray, dip or double vacuum.
Decay Resistance and Water Repellency Standards
The DryVac 1010 meets the CSA A440-M90 standard for a wood preservative used to treat wood window frames and sashes. The CSA standard has requirements of anti-fungus activity as measured in a soil block test, and its ability to resist swelling when immersed in water (swellometer test).
Its fungal resistance and water repellency has been tested in accordance with NWWDA (National Wood Window and Door Association) protocols TM-1 (soil block test) and TM-2 (swellometer test) and has been shown to meet both standards: the water repellency efficiency is over 60%.
Paint Adhesion
The water repellency properties of a millwork treatment must not affect paint adhesion. Wood treated with DryVac 1010 has excellent adhesion both to oil based enamel paints and to water based latex paints. DryVac 1010 meets the CSA A44-M90 paint adhesion standard.
Active Ingredient
The active ingredient of DryVac 1010 is 0.5% by weight propiconazole. L-joints treated with solutions at this strength of propiconazole exhibited total resistance to decay after 77 months of exposure in tests being carried out at Saucier, Mississippi, and L-joints treated with one quarter this strength of propiconazole (0.125%) were also indicating good resistance to fungus under conditions that caused severe decay on untreated L-joints.
Tests with propiconazole solutions show that it has better long term resistance to fungus attack than competitive products presently on the market. These tests are still on-going.
