Woodbond 1920 is a one-component polyvinyl acetate (PVA) emulsion adhesive that meets the ASTM D-5572-99 dry use standard for finger jointing of interior wood products, such as trim molding. However, manufacturers can simply mix the adhesive with an aluminum chloride catalyst to create a low-cost, highly water-resistant adhesive that easily surpasses the ASTM D-5572 wet use standard for non-structural lumber products to be exposed to outdoor elements.
Mixing of this product is
quick and easy. Within five to 10 minutes, the manufacturer can make a powerful,
water-resistant adhesive with a minimum pot life of eight hours.
In addition to its
versatility, Woodbond 1920 also speeds up production through its shear-thinning
formulation, enabling effortless extrusion into most finger joint application
systems. The adhesive can also be filtered directly from the tote, thus minimizing
equipment clogging. And a low minimum use temperature range of 40 to 43° F enables manufacturers to use this
adhesive further into colder seasons or on chillier mornings.
