环氧树脂

​ST 94

​单面 SPRINT™
  • 优化的悬垂性和粘性,优异的操作性
  • 非常适合于复合或垂直成型
  • 力学性能和韧性之间的良好平衡

ST 94 单面 SPRINT™是一种模压成型材料,它由一层胶合到预制、预催化树脂膜上的干增强材料构成。

ST 94 系列是增韧的热熔、环氧树脂,提供极好的力学性能平衡。它的配方使得其在车间温度下能够提供理想的黏度等级。它是制造结构部件的理想材料,其中改进的抗冲击性和抗树脂微裂纹能力是我们所需要的。ST 94 具有灵活的固化工艺,从 85℃ 下 12 小时到 120℃ 下 45 分钟。 这使得它适用于常规部件生产以及试验部件的开发。

典型应用

单面 SPRINT™ 已开发用于大型船用结构,其中高克重材料需要在这种产品的长期使用期间在模具中保持完好无损。
