    • A shaped strip of highly reflective aluminum protected by an anodic oxide coating and a light-permeable fluoropolymer coating which is non-adhesively interstitially mechanically bonded to the microscopic irregularities of the anodic oxide surface. There is no adhesive used to obtain chain entanglement. The highly reflective strip may be substituted for polished stainless steel and/or bi-metal and used under comparably aggressive conditions for a prolonged period without deleteriously affecting the initial D/I (distinctness of reflected image) of the shaped strip. The strip of arbitrary length is shaped in rolling dies so that at least a portion of the strip has a radius of less than 10 mm without damaging or separating the fluoropolymer coating. The specific steps of the claimed process require starting with a clean strip which is brightened to a nearmirror-like finish, then treated to carry a thin porous aluminum oxide coating in a phosphoric acid bath under direct current (DC). After rinsing and drying, the reflective surface is coated with the fluoropolymer while maintaining at least 80% D/I. The strip, now dual-coated, is then formed to a desired profile. The dual-coated strip, in turn, may be treated with a corona discharge to activate its surface so as to non-adhesively bond an adhesive chosen to bond a thermoplastic strip of synthetic resin to the activated fluoropolymer surface.
    • 由阳极氧化物涂层保护的高反射性铝的成形条和与阳极氧化物表面的微观不规则性非粘性间隙机械结合的透光性氟聚合物涂层。 没有粘合剂用于获得链缠结。 高反射条可以代替抛光的不锈钢和/或双金属,并且在相当的侵蚀性条件下长时间使用,而不会有害地影响成形条的初始D / I(反射图像的明显性)。 任意长度的条带在轧模中成形,使得条带的至少一部分具有小于10mm的半径,而不损害或分离含氟聚合物涂层。 所要求保护的方法的具体步骤需要从洁净的条状物开始,该条被亮化成近似镜面的光洁度,然后在直流(DC)下处理以在磷酸浴中携带薄的多孔氧化铝涂层。 冲洗和干燥后,反射表面用含氟聚合物涂覆,同时保持至少80%的D / I。 然后将现在双涂层的条形成为期望的轮廓。 双重涂覆的条带又可以用电晕放电来处理以活化其表面,从而将选择的粘合剂粘合到粘合合成树脂的热塑性带的活性氟聚合物表面上。

    • A strip of gray reflective aluminum protected by a conversion coating and a light-permeable fluoropolymer coating which is non-adhesively interstitially mechanically bonded to the microscopic irregularities of the conversion coated surface. The highly reflective strip may be substituted for polished stainless steel and/or bi-metal and used under comparably aggressive conditions for a prolonged period without deleteriously affecting the initial D/I (distinctness of reflected image) of the shaped strip. The strip of arbitrary length may be shaped in rolling dies so that at least a portion of the strip has a radius of less than 10 mm without damaging or separating the fluoropolymer coating. The specific steps of the claimed process require starting with a bright-rolled clean strip which is conversion coated to carry a thin metal compound coating. After rinsing and drying, the reflective surface is coated with the fluoropolymer while maintaining at least 80% D/I. The strip can then be formed to a desired profile and treated with a corona discharge to activate its surface so as to facilitate non-adhesively bonding of a thermoplastic strip to the activated fluoropolymer surface.
    • 由转化膜保护的灰色反射铝条和透光性氟聚合物涂层,其与粘合的间隙机械地结合到转化涂覆表面的微观不规则部分。 高反射条可以代替抛光的不锈钢和/或双金属,并且在相当的侵蚀性条件下长时间使用,而不会有害地影响成形条的初始D / I(反射图像的明显性)。 任意长度的带材可以在轧制模具中成形,使得条带的至少一部分具有小于10mm的半径而不损坏或分离含氟聚合物涂层。 所要求保护的方法的具体步骤需要从光滑的清洁带开始,其被转化涂覆以承载薄金属化合物涂层。 冲洗和干燥后,反射表面用含氟聚合物涂覆,同时保持至少80%的D / I。 然后可以将条带形成为期望的轮廓,并用电晕放电来处理以激活其表面,以便于将热塑性条带非粘合地粘合到活化的含氟聚合物表面。
