Product Description Lineco acid-free adhesive has excellent lay-flat properties, dries clear, and adheres to most porous surfaces. The easy-to-use polyvinyl acetate (PVA) formula is fast-setting and re-moistenable with water. Formulated specifically for preservation materials, it will not become brittle with age. Take advantage of the lower cost on gallon containers of adhesives and use our rugged, reusable plastic pump to dispense small quantities of glue without drips, spills, or sticky messes to clean up. Note: Freezing temperatures adversely affect these adhesives and we are unable to ship during cold temperatures because of this. We regret any inconvenience.
