酚醛环氧树脂
CYDBN-240、240高耐热环氧树脂的分子刚性很大,固化物具有很高的耐热性能以及耐温性能,特别是高温性能保持率最高(相比于其它酚醛环氧树脂),可作为改性材料用于提高体系高温性能的电子层压材料、粉末涂料(具有更高的反应性)、末塑料、液体绝缘涂料、各种结构工程材料、增强塑料及其预浸料坯、高耐热胶粘剂、油墨等场合,为固化体系带来更高的玻璃化转变温度及交联密度,以提高抗湿性、抗溶剂性、抗环境性,在环境温度及较高的温度下提高强度、刚性、电性能及其它性能保持率。在预浸层压材料中使用CYDBN可获得最高的高温强度保持率及稳定性,在环氧树脂素料中使用CYBN可获得突出的流动稳定性和更短的模具占用周期。
 
Phenolic epoxy resin
Due to the high rigidity of its molecules, high-temperature-endurance and good thermal resistance after being cured, especially the best relention of propertyes at high temperature(compared with other novolac epoxy resins), CYDBN-240 and 240E high-temperature-endurance epoxy resin can be used as a modifier for electronic laminateon, powder coating( with better reactiveity), mould plastics, liquid insulateon coating, engineering materials of various structure, reinforced plastics and its predipping embryo, thermal resistance adhesive and printing ink to produce highter glass transition point and crosslinking density for cured systems. As a result, the resistance to humidity, solvent and environment can be strengthened, the retention of intensity, rigidity, electric property and other performance reinforced under atmospheric environment and high temperature. When applied in predipping laminating materials, the highest retention of intensity at high temperature and thermal stability can be achieved. When used in epoxy resin plastics, a remarkable flow slability and shorter occupancy period of mould are available.
