X21

硕士邦德聚合物系统X21是一种特殊配方的单组分丙烯酸酯聚合物高性能涂料，粘接，密封，浸渍树脂体系的基础。 它含有50％的溶剂，容易暴露于空气中蒸发，尤其是在在温度升高。 硕士邦德聚合物系统X21是一个很清晰的解决方案，空气干燥速度极快，形成具有超强硬度，耐磨性好，良好的清晰度，甚至在户外长时间暴露保色性硬无色膜。 这种聚合物系统债券以及在这两个剥离和剪切许多相似和不同的表面，包括金属，木材，大多数塑料，陶瓷，玻璃，橡胶，造纸，皮革，墙板等保温产品以及塑料泡沫等初始设置一旦发生了大量的溶剂已被删除。 硕士邦德聚合物系统X21不碳化后加热到高温。 所有表面应仔细清洗和干燥前申请。 他们应该为达到最佳效果的油脂，油，灰尘和其他污染物。 如溶剂清洗，蒸汽除油，浸蚀等传统清洗方法是适用的。 确定一个彻底的清洗简便的方法是放置在“清理”表面几滴冷水。 如果水形成连续膜，清洁是令人满意的。 硕士邦德聚合物系统X21很容易是一个可流动的液体。 它可以进一步降低粘度，加入如丙酮，丁酮，甲苯等溶剂，以最好地满足特定的应用需求。 硕士邦德X21具有优良的耐水性，是一个卓越的电气绝缘。

Master Bond polymer system X21 is a specially formulated one component acrylic polymer based resin system for high performance coating, bonding, sealing and impregnation. It contains 50% solvent which readily evaporated upon exposure to air especially at elevated at temperatures. Master Bond polymer system X21 is a very clear solution which air dries extremely fast to form hard colorless films with superior hardness, good abrasion resistance, excellent clarity and color retention even upon prolonged outdoor exposures. This polymer system bonds well in both peel and shear to many similar and dissimilar surfaces including metals, wood, most plastics, ceramics, glass, rubber, paper, leather, wallboard and other insulation products as well as to plastic foams etc. An initial set takes place as soon as a significant amount of the solvent has been removed. Master Bond polymer system X21 does not carbonize upon heating to high temperatures. All surfaces should be carefully cleaned and dried prior to application. They should be free of grease, oil, dirt and other contaminants for optimal results. Conventional cleaning methods such as solvent washing, vapor degreasing, etching etc are applicable. A convenient way of determining thorough cleaning is to place a few drops of cold water on a “cleaned” surface. If the water forms a continuous film, cleaning is satisfactory. Master Bond polymer system X21 is readily is a flowable liquid. It can be further reduced in viscosity by adding solvents such as acetone, MEK, toluene etc. so as to best meet specific application needs. Master Bond X21 has excellent water resistance and is a superior electrical insulator.
