  • Patent number: 5429882
    Abstract: A corrosion-resistant colored architectural material which is essentially lead free and is not highly reflective. The coating on the material is a two-phase metallic coating comprised of a large weight percentage of zinc and a relatively large weight percentage of tin. The tin-zinc coating may also include nickel and copper. The tin-zinc composition provides for both a highly corrosive-resistant coating which protects the surface of the architectural material from oxidation and also produces a gray, earth tone colored which is not highly reflective.

  • Patent number: 5395702
    Abstract: A weather-resistant strip roofing material having improved corrosion-resistant properties includes a strip of stainless steel which is pre-treated by an aggressive pickling process and/or a chemical activating process prior to applying a hot-dip tin coating, The pre-treatment of the stainless steel strip produces superior alloying between the stainless steel and the tin coating which reduces flaking of the tin coating.

  • Patent number: 5395703
    Abstract: Various metal coatings have been used for many years to inhibit oxidation of metals exposed to the natural elements of the atmosphere over a period of time. Terne alloy coatings which normally contain about 20% tin and about 80% lead are some of the most popular metal coating treatments to resist corrosion. The special formulation of the present invention reformulates the terne coating to constitute a tin and lead based coating where tin constitutes at least 90% of the terne and lead amounts to less than 0.1% and preferably less than 0.05% of the terne. The low lead terne coating may also include antimony and bismuth to provide strength and hardness to the low lead terne formulation having corrosion resistive qualities similar to that of standard terne coating formulations.

  • Patent number: 5296300
    Abstract: A method of treating a terne coating to accelerate the patina on the terne coating. The terne coated metal is coated with a specially formulated asphalt based paint which produces a semi-transparent or translucent, dull finish on the terne coated metal. The coated terne coated metal is then exposed to the natural atmospheric elements for at least six months wherein such time enhanced oxidation of lead and tin occurs.

  • Patent number: 5061022
    Abstract: A door closure arrangement is provided for a paint cabinet or like enclosure containing combustible materials. Right and left hand doors are hinged to door jambs in the cabinet's opening and an overlapping lip is provided on one of the doors to insure that no gap between the doors exists when the doors are closed. Door closures, held in an open position by temperature sensitive fusible links, rotate the doors from an open to a closed position should a fire melt the fusible links. A spring biased, lever actuated door sequencing mechanism insures that the doors closed in proper sequence without interference from the overlapping lip. A spring biased, lever actuated mechanism automatically latches or locks the doors when they are rotated into the closed position whereby the adverse effects of the fire on the contents of the cabinet are minimized.
