39、tions covered by this specification are intended for use in paints and enamels. The resin portions are all of the oxidizing type but vary in oil length and in the nature of the oil modi- fier. All of the resin solutions air-dry, with normal drier concentrations, within 7 hours or less, and they are
40、also suitable for baking at from 200 to 30OoF. 6.1.1 Type I (long oil soya, safflower or sunflower) and type V (long oil tall oil) resin solutions should be used in products requiring maximum ease of brushing combined with color retention and durability. These include architectural enamels, structur
41、al and machinery paints, and primer; also, marine, trim, house, and sign paints. 6.1.2 Type II (long oil linseed) resin solution is useful in red lead primers and other structural paints. for a.varnish type of product and it dries to a high gloss. its brushing properties are excel lent 6.1.3 The typ
