Abstract: Specific color imparting compounds, including pigments and catalysts are used to produce a polyester resin having a green color. The compounds are added during polymerization of the polymer and the resins produced can be utilized to make various containers or packages to hold liquids or solids.
Abstract: A water-displacing paint is disclosed for coating metallic surfaces in hu environments to prevent corrosion. The paint comprises controlled proportions of a silicone alkyd resin to serve as a binder and physical barrier, solvents including ethyl acetate, aromatic mineral spirits and 1,1,1 trichlorotrifluorethane for ensuring water immiscibility, a petroleum sulfonate to inhibit corrosion and aid surface absorption, and an organo-titanate of isopropyl tri-titanate to promote surface adhesion. Selected amounts of titanium dioxide and zinc molybdate are included as pigments in one effective example of the paint to provide it a white color. Alternate colors may be produced conventionally by adding standard tinting pigments in amounts sufficient to yield the desired color.
