使用拉力试验机的羟基化产物进行应力应变性能测试。将羟基化产物与HDI复配搅拌30min后，用线棒刮涂在马口铁上，常温固化6h，100℃固化1h。分别按照相应的国家标准进行硬度测试，柔韧性测试，附着力测试以及抗冲击测试。

Stress-strain properties were tested using hydroxylation products from tensile testing machines. The hydroxylation product and HDI were mixed and stirred for 30min, then coated on the tinplate with a wire rod and cured at room temperature for 6h and at 100℃ for 1h. Hardness test, flexibility test, adhesion test and impact test are carried out according to the corresponding national standards.
