Abstract: This invention provides an additive for Portland Cement comprising acrylic monomers and copolymers, wetting agent, polypropylene glycol and silicone.

Abstract: The invention relates to a polish including acrylic polymers and a wetting agent comprising a high-weight alcohol mixed with glycol-n-butyl ether.

Abstract: New epoxy resin binder compositions which have outstanding pot life but can be cured to form products having excellent physical properties are obtained by mixing the epoxy resin with a new curing agent comprising a reaction product of methylene chloride and monoethanol amine in special proportions. The new binders are particularly suited for use in combination with Portland cement, sand and water to form improved overlay coatings for already form concrete or asphalt surfaces.

Abstract: A device for use in applying a thin resinous coating to existing surfaces, such as concrete highways, to resurface and restore the same and improve their physical properties, such as skid resistance comprising two parallel supporting beams, a screed box having a bottom, two sides and a front and back sides, the bottom of which is attached to the parallel beams and the screed box having an adjustable dispersing gate at the back adapted to dispensing a controlled amount of the resinous binder in the box, at least one rotatable screed brush adjustably attached between the two beams behind the screed box and being adapted to bringing the dispersed binder in contact with the surface and pushing out any air that may be trapped under the coating, at least two spaced levelling bars perpendicularly and adjustably attached between the beams and being adapted to spreading and levelling the binder passing under the brush, at least one of the levelling bars being adapted to applying downward pressure on the layer of binde

Abstract: A deep penetrating sealer composition which renders the treated surface resistant to water, metal ions and chloride ion penetration comprising a mixture of (1) an aromatic solvent, (2) a chlorinated solvent, (3) an aliphatic hydrocarbon solvent, and (3) a hydroxy-substituted polyorganosiloxane.

Abstract: Solutions useful for stripping coatings from coated substrates and conditioning the substrate for subsequent coating treatment are obtained by mixing in special proportions (1) a solvent composition comprising a chlorinated solvent and a liquid alcohol containing at least three carbon atoms, (2) a wetting composition comprising basic metal ammonium salt of an aromatic sulfonic acid, and a non-ionic surface active material, and (3) a vapor suppressant and said mixture preferably containing a small amount of water. A method for using these solutions for stripping and conditioning coated substrates, and particularly metal substrates, is also disclosed.

Abstract: A paint stripper composition able to remove a variety of paint systems employing methylene chloride as the active solvent for the composition further includes an amine-glycolate acid salt having a pH of 5 which aids in the swelling of the subsurface of the paint system that is to be removed, thus allowing the permeation of salt complex in conjunction with the chloride ion portion of the methylene chloride to cause a releasing action of the paint bond from the substrate material such as metal, wood, glass, fabric or plastic. The composition further includes a vapor pressure depressant such as paraffin wax, a viscosity increasing agent, and other solvent materials to aid in the stripping action. The composition is substantially totally bio-degradable, is low in toxicity and is further characterized by the variety of paint systems which can be effectively removed by the composition and its ability to remove carbon deposits on metal parts and surface rust from metal and chrome plated surfaces.
