  • Process for producing a paper container having high impermeability to liquid
    Patent number: 4206249
    Abstract: A process for producing a paper container having high impermeability to liquid comprising spray coating a polymerizable solution containing a prepolymer, photosensitizer and/or reactive diluent onto a wall surface of previously fabricated paper containers, allowing the prepolymer and/or reactive diluent to polymerize by an ultraviolet irradiation to thereby form a liquid impermeable coating on the wall surface of the container.

  • Process of coating aluminum materials molded by extrusion with polysiloxane coating
    Patent number: 4115607
    Abstract: Shaped aluminum bars fresh from an extruder machine are coated with a specific organopolysiloxane composition while remaining uncooled and staying at temperatures not lower than about 250.degree. C, or at a temperature between about 550.degree. and 250.degree. C. The thus coated aluminum bars are then, preferably, subjected to annealing. The coatings formed on the surfaces of the aluminum materials have a superior resistance to attack by chemicals, weather, stains and heat as well as excellent adhesion and mechanical properties.
