Abstract
Solvent free liquid masking compositions comprise from about 5 to about 20 percent by weight of an aliphatic polyol; from about 5 to about 20 percent by weight of a plasticizer; from about 0.1 to about 1 percent by weight of a surfactant; and sufficient water to total 100 percent by weight. A method for protecting selected surfaces from paint in painting operations comprises applying a solvent free liquid masking composition to selected surfaces of an object where paint subsequently applied is not desired; allowing the liquid masking composition to dry, forming a film; painting the object, whereby surfaces carrying the film are protected from the application of paint; and removing the film.
Claims16
Solvent free liquid masking compositions comprising:
- from about 5 to about 20 percent by weight of polyvinyl alcohol;
- from about 5 to about 20 percent by weight of a plasticizer;
- from about 0.1 to about 1 percent by weight of a surfactant;
- and
- sufficient water to total 100 percent by weight, wherein said masking composition is water-soluble and devoid of volatile organic chemicals;
- it is devoid of polymer resins other than polyvinyl alcohol in amounts sufficient to render the film water-insoluble and is stain resistant to applied surfaces.
A method for protecting selected surfaces from paint in painting operations comprising:
- applying a solvent free liquid masking composition to selected surfaces of an object where paint subsequently applied is not desired;
- allowing said liquid masking composition to dry, forming a film;
- painting said object, whereby surfaces carrying said film are protected from the application of paint;
- and
- removing said film, wherein said solvent free liquid masking composition comprises
- from about 5 to about 20 percent by weight of polyvinyl alcohol;
- from about 5 to about 20 percent by weight of a plasticizer;
- from about 0.1 to about 1 percent by weight of a surfactant;
- and
- sufficient water to total 100 percent by weight, wherein said masking composition is water-soluble and devoid of volatile organic chemicals;
- it is devoid of polymer resins other than polyvinyl alcohol in amounts sufficient to render the film water-insoluble and is stain resistant to applied surfaces.
Solvent free liquid masking compositions consisting essentially of:
- from about 5 to about 20 percent by weight of an polyvinyl alcohol;
- from about 5 to about 20 percent by weight of a plasticizer;
- from about 0.1 to about 1 percent by weight of a surfactant;
- and
- sufficient water to total 100 percent by weight, wherein said masking composition is water-soluble and devoid of volatile organic chemicals and is stain resistant to applied surfaces.
