UV15-7SP4

硕士邦德聚合物系统UV15 – 7SP4是一个新的组件，光学透明，增韧紫外线和/或延长服务能力为-80 ° F至+250 ° F。固化聚合物系统 它是100％反应，不含有任何溶剂或其他挥发性物质甚至不暴露于脆化温度低的服务。 当暴露在适当波长的紫外光源和足够的强度，它迅速固化到产品坚固耐用不黄变和耐化学性粘合剂，密封剂，具有优良的电绝缘性能的涂料。 聚合物材料的紫外光固化具有低收缩率，优异的附着力，以各种基材，硬度和耐久性厚部分达一英寸多.200。 与其他任何商业紫外光固化产品主键UV15 – 7SP4聚合物体系不抑制空气和部分展品甚至在一英寸的厚度大于0.200更大的一个理想的环境温度下固化速度快。 固化时间取决于紫外线灯，波长和发射的紫外线辐射，灯的距离从UV15 – 7SP4，该科的厚度被治愈，等顶面金额类型 典型的固化时间范围为5-10秒的小环境温度为2-3分钟。 在商业销售200瓦特/英寸的中压汞蒸气或相当于紫外线光源建议。 最大紫外吸收发生在280-360纳米范围内进行。 无溶剂或其他蒸汽被释放在固化的过程，需要以最小的收缩从液态到固态的地方。 固化胶粘剂，密封剂和涂料表现出最理想的性能配置，包括优秀的耐用性，韧性，抗热震性，灵活性，不泛黄的颜色以及优良的附着力，从玻璃钢聚酯薄膜和聚碳酸酯多种基材。

Master Bond Polymer System UV15-7SP4 is a new one component, optically clear, toughened UV and/or curable polymer system with extended service capability of -80°F to +250°F. It is 100% reactive, does not contain any solvents or other volatiles and does not embrittle even upon exposure to low service temperatures. When exposed to a source of UV light of appropriate wave lengths and adequate intensity, it cures quickly to product tough and durable non-yellowing and chemically resistant adhesives, sealants and coatings with excellent electrical insulation properties. The UV cured polymeric material features low shrinkage, excellent adhesion to various substrates, hardness and durability in thick sections up to .200 of an inch and more. Unlike any other commercially UV curable products Master Bond UV15-7SP4 polymer system is not inhibited by air and exhibits a desirable fast curing rate at ambient temperatures even at section thickness greater than .200 of an inch. Cure time depends on the type of UV lamp, the wave lengths and the amounts of the emitted UV radiation, distance of the lamp from the top surface of the UV15-7SP4, the thickness of the section to be cured,etc. Typical cure times range from as little as 5-10 seconds to 2-3 minutes at ambient temperatures. Commercially marketed 200 watt/inch medium pressure mercury vapor or equivalent UV light sources are recommended. Maximum UV absorption takes place in the 280-360 nanometer range. No solvents or other vapors are released during the curing process which takes place with minimal shrinkage from the liquid to the solid state. Cured adhesives, sealants and coatings exhibit a most desirable performance profile including outstanding durability, toughness, thermal shock resistance, flexibility, non-yellowing color as well as excellent adhesion to many substrates ranging from glass and steel to polyester films and polycarbonates.
