Abstract:
The present invention relates to a coating composition which is excellent in handling and safety, enables the curing of the resultant coating composition at low temperature, and provides an excellent adhesion to polyolefin resin moldings. The coating composition comprises (1) 40-90 wt. % of a grafted and chlorinated polyolefin oligomer obtained by graft polymerizing a vinyl polymerizable monomer to a chlorinated polyolefin, the grafted and chlorinated polyolefin oligomer having a primary or blocked primary hydroxyl group at a position of 15 to 40 atoms away from the vinyl graft polymer chain grafted to the chlorinated polyolefin, a number average molecular weight of 5,000 to 50,000, 0.4 to 2.5 mole/kg-resin of a primary or blocked primary hydroxyl group, 50 to 95 wt. % of said vinyl graft polymer chain, and 5 to 50 wt. % of the chlorinated polyolefin used as a starting material, and (2) 60 to 10 wt. % of an imino-type, methylol-type or complete alkoxy-type melamine resin. The present coating composition can be cured by baking the coating composition at 90.degree. to 120.degree. C.
Abstract:
A thermosetting resin composition which can be used to produce pultruded products with a lustrous surface finish comprises about 60% to about 95% by weight of an uncured, liquid phenolic resin containing about 70-90% solids by weight and about 5 to about 40% of particles of a molding composition comprising an uncured, solid phenolic resin and a suitable filler.
Abstract:
Spherical fine particles of colored resin are provided. The fine particles are of a spherical shape and are superior in heat resistance, solvent resistance, and chemical resistance, and sufficiently satisfactory in durability and coloring, and industrially advantageous. The spherical fine particles of colored resin are made by incorporating an amino resin cured matter and an inorganic pigment into one body, and a ratio of the inorganic pigment against a total amount of the amino resin cured matter and inorganic pigment is in a range of from about 1 to 30% by weight.
Abstract:
The flame retardance of polyurethane foams is improved by dispersing in a polyol used to make the urethane foam a finely divided resin composition composed of 60-85 wt % of an aminoplast resin filled with 40 to 15 wt % of an aminoplast resin filled with 40 to 15 wt % of cellulose fiber.

A protective coating composition containing certain polyester polyols and an aminoplast derivative is applied to a thermoplastic substrate to produce a thermoformable article having mar- and solvent-resistance.
Abstract:
The present invention relates to an enclosure member consisting essentially of solid, non-aromatic polymers that have a linear carbon to carbon backbone structure and have a plurality of free hydrogen atoms attached to the carbon atoms with a permeability to wet and dry solvents and fuels of less than 1/50, of the permeability of untreated enclosure members having a thickness of 1 mm, a portion of the hydrogen atoms of the surfaces of said member having been replaced by sulphonic acid or sulphonate groups and being coated with a cured thin layer of a mixture of a resin made by the reaction of urea and formaldehyde, respectively of melamine and formaldehyde, with furfuryl alcohol, and an oligomer consisting of a polymer of furfuryl alcohol and formaldehyde.
Abstract:
The present application relates to enclosure members consisting essentially of solid, non-aromatic polymers that have a linear carbon to carbon backbone structure and having a plurality of free hydrogen atoms attached to the carbon atoms with a permeability to wet solvents and fuels of less than 1/7, optionally less than 1/40 of the permeability of untreated enclosure members having a thickness of 1 mm. Said low permeability is due to the presence of a layer of an iron phenanthroline complex on at least the inner surface of said enclosure members, having a portion of the hydrogen atoms replaced by sulfonic acid or sulfonate groups.
Abstract:
Phenol formaldehyde resin foams which do not burn or smoulder and which are self-extinguishing are manufactured by a process in which the phenol formaldehyde condensate is blown in the presence of a nitrogenous additive which is the condensate of formaldehyde with an amine or may be the amine salt of a mild inorganic acid. The smouldering characteristics of prior phenol formaldehyde are overcome.
