  • Rust removal process using removable coatings of maleic acid copolymers
    Patent number: 4517023
    Abstract: Rust is removed from metal surfaces by applying a coating of an aqueous solution of a copolymer of maleic acid and monomer of the formula CH.sub.2 .dbd.CHR wherein R represents H, CH.sub.3, OR.sup.1 or OCOR.sup.1 and R.sup.1 represents CH.sub.3 or CH.sub.2 CH.sub.3. The rust becomes incorporated into the coating during drying and the coating detaches itself from the metal surface for easy removal.

  • Method of improving the wet tensile strength of glass fiber mats
    Patent number: 4430158
    Abstract: What is described herein is a method of improving the wet tensile strength of sized glass fiber mats characterized by forming the mat from a plurality of glass fibers and a binder composition therefor which consists essentially of a urea-formaldehyde resin and about 0.01 to 5% by weight of a surfactant which is both highly water soluble and which wets the surfaces of sized glass fibers. The preferred surfactant is an anionic surfactant such as a sodium dodecylbenzene sulfonate. The glass mats thus made retained up to 79% of their tensile strength upon being subjected to severe wet conditions.
