Titebond III Ultimate Wood Glue Suitable for wood, cloth and leather Initial Tack time 30 mins Setting time 24 hours approximately Passes ANSI/HPVA Type I water-resistance Waterproof formula that cleans up with water Superior strength - strong initial tack Designed for interior and exterior applications Longer open assembly time Lower application temperature Unaffected by finishes FDA approved for indirect food contact Conforms to ASTM D-4236 Specification for Titebond III Ultimate Wood Glue: Setting Time 45 mins/24 hours Size 3.8L Suitable For Wood, Cloth, Leather, Craft Type Advanced Proprietry Polymer From Franklin of USA, described as an APP (Advanced Proprietary Polymer), Titebond III has been formulated as a dedicated wood glue to give you the ease of application of aliphatic/PVAs and the water resistance of polyurethane glues. Making an exceptionally strong bond on wood-to-wood joints, it has longer open time and higher viscosity than conventional PVAs and will maintain integrity at lower application temperatures. All of which makes for easier and less fraught assembly procedures. Polyurethane glue has undoubted flexibility of use and massive strength but is a very persistent adhesive, difficult to clean up from equipment and particularly hands. Titebond III has been designed to give you the strength of wood-to-wood bonds without the problems. It cleans up with water whilst wet, sands off without softening when fully cured, is unaffected by finishes, solvent and heat and is mildew resistant. It is suitable for interior and exterior use. Titebond III Ultimate wood glue has been independently tested for lead, cadmium and other metals under ASTM F963 and 16 CFR 1303 (total lead content). These are the testing methods specified for toy safety under the U.S. Consumer Product Safety Commission. It has also reviewed by an independent toxicologist and conforms to ASTM D4236 for art and craft materials.
