PHENOXY PKHH Resin
聚酚氧树脂
Product Description
Product Description
PHENOXY HH是一种韧性、延展性、无定形的热塑性聚合物,具有优异的热稳定性、粘合强度和隔汽性能。
PHENOXY树脂可以通过其羟基官能团与异氰酸酯、三聚氰胺树脂或酚醛树脂反应进行交联。
交联的PHENOXY树脂在许多基材上表现出优异的耐化学性、硬度和附着力,包括钢、铝、玻璃、碳纤维、尼龙和聚酯(PET)等塑料。
PHENOXY PK HH树脂也可以配制成含有潜在硬化剂(如双氰胺)的单组分环氧树脂,在适当条件固化,可以提高韧性和粘合强度。
PHENOXY PK HH树脂可溶于许多极性、非质子溶剂,如MEK、乙二醇醚。
PKHH应用在涂料中,增加涂料对特殊表面的接着强度、增加涂料的韧性及硬度、提高涂料的耐蚀性、耐括性。
PKHH在胶粘剂中的应用:有效改善胶粘剂的粘接强度、韧性、硬度、耐热性、气体遮蔽性、拉伸强度、耐湿性。
PKHH在复合材料中,改善树脂的韧性及强度、增强复合材料的抗张性,调整硬化速度、提高耐热性、耐湿性。
PKHH在工程塑料中,提高工程塑料的抗张性、张力模数、弯曲模数、耐冲击强度、填料分散、澄清及色粉分散、隔汽性能。

Storage
PHENOXY PK™ HH resin should be stored in a dry place, in its sealed original container, at temperatures between 0°C - 40°C (32°F - 104°F). Under these storage conditions the product has a shelf life of 10 years from date of manufacture. The product should not be exposed to direct sunlight. Phenoxy resins may absorb water, ~1% by weight, if exposed for long periods of time to the atmosphere. Pellets can be dried at 80 - 90 ⁰C if desired
