Abstract: A composite material comprising a metallic substrate and a coating on at least one side of the metallic substrate, wherein the coating comprises an acrylic or styrene-acrylic based polymer and is less than 0.00508 mm (0.2 mils) thick, wherein the polymer has a molecular weight of 50,000 to 1,000,000, a glass transition temperature (Tg) of 50-80oC, and comprises 90-100 wt. % of the total solids in the coating. The method of applying a coating to a metal substrate using a manifold flood and squeegee roll configuration or alternatively roll coater techniques; wherein the roll hardness, shape, pressure and speed are chosen to ensure that the coating composition forms a continuous wet film on the metallic substrate surfaces when the strip travels at up to 600 feet per minute; and the wet film has a uniform thickness of 0.0508 mm (2 mil (0.002 inch)) or less.

Abstract: A"faux stainless steel" may be produced by processing galvanized carbon steel through a temper mill using textured rolls to develop a "polished" type surface. The galvanized coating is not removed by abrasion but is compressed thereby providing a more uniform substrate than conventional polishing or brushing. The resulting strip may then be coated with an organic film to provide additional appearance and corrosion benefits including anti-fingerprint resistance.
Abstract translation: 可以通过使用纹理辊的回火机加工镀锌碳钢以形成“抛光”型表面来生产“人造不锈钢”。 镀锌涂层不是通过磨损而被去除，而是被压缩，从而提供比常规抛光或刷涂更均匀的基底。 所得到的带材然后可以涂覆有机膜，以提供额外的外观和腐蚀效果，包括抗指纹抗性。

Abstract: A process involves the continuous surface treatment of stainless steel coils with aqueous suspensions of rare earth oxide nano or micro particles or aqueous rare earth nitrate solutions of nano or micro particles. The surface treatment can be applied by roll coating, spraying or other conventional application techniques. The treated material in coil form is then heated in an annealing box using an open coil process whereby a wire is placed between coil laps to promote uniform atmosphere exposure. The atmosphere can be reducing or oxidizing and the times can vary from 1 hr to 100 hr. The atmosphere can also be wet (high dew point) or dry (low dew point). The surface treatment promotes a more uniform color to the subsequently developed oxide formed during anneal-type heat treatment. It also improves corrosion resistance of the processed stainless steel material. Materials treated in this manner are suitable for a variety of applications in the building systems, automotive and appliance markets.
Abstract translation: 一种方法涉及用稀土氧化物纳米或微米颗粒的含水悬浮液或纳米或微米颗粒的稀土硝酸盐水溶液对不锈钢卷材进行连续表面处理。 表面处理可以通过辊涂，喷涂或其他常规应用技术来施加。 然后使用开放线圈工艺在退火箱中加热线圈形式的处理过的材料，由此将线放置在线圈圈之间以促进均匀的大气暴露。 大气可以减少或氧化，时间可以从1小时到100小时不等。 大气也可以是潮湿（高露点）或干燥（低露点）。 表面处理促进了在退火型热处理过程中形成的随后形成的氧化物更均匀的颜色。 它还提高了加工不锈钢材料的耐腐蚀性。 以这种方式处理的材料适用于建筑系统，汽车和家电市场中的各种应用。
