航空航天工业的结构胶粘剂系统

已经开发了一种和两个组分环氧化合物,用于航空粘合,灌封,灌装和修复应用。这些高性能组合物可用于低粘度和高粘度。具体等级符合美国国家航空航天局的低分散规范,并符合UL 94V-0阻燃性要求,在远程标准14 CFR 25.853(A)下通过垂直和水平烧伤测试。这些RoHS标准的产品不含任何高度关注(S必威appVHC)的物质。此外,等级通过波音规格BSS 7238修订C用于低烟,7239修订A.毒性。他们也已成功测试空中空客气点火,烟雾密度和毒性。

用于航空航天应用的结构增韧粘贴粘合剂的益处

  • 高粘合强度与相似且不同的基材,包括复合材料,铝,不锈钢和钛
  • Resistance to cyclic fatigue
  • High peel strength
  • 卓越的耐用性和韧性
  • Exceptional compressive strength
  • 快速设置系统
  • 定制包装
  • 高玻璃过渡温度
  • 自动应用

Structural paste formulations have low sag properties, can fill gaps between bonding surfaces and are excellent for use on vertical substrates. They are easy to apply, can be precisely dispensed, can be stored at ambient temperatures. While two component systems often feature a long working life, single component no mix products have an "unlimited" working life. Select grades are engineered to cure rapidly at low temperatures. Systems are available for autoclave and out-of-autoclave bonding. These compositions are most effective in joining different shapes and thicknesses, even thin substrates. Most significant, they improve the distribution of stresses over bonded joints, protect against corrosion, enhance aerodynamics, aesthetics, eliminate hole drilling, protruding fasteners, deliver smooth contours, save time, lower weight, decrease costs. Innovative grades will sustain performance in extreme operating environments including high/low temperatures. These solvent free compounds also exhibit impact, micro-crack resistance, withstand numerous chemicals and enable design flexibility for aircraft manufacturers.

主键B阶段的环氧薄膜粘合剂已准备好使用,不需要混合,特征控制流动,用于最大键合完整性,一致的粘合线厚度。它们可用于厚度和重量范围内的纸张或卷。这些结构粘合剂具有金属金属,复合粘合,蜂窝夹层结构应用的高粘合强度。它们在适度的温度下表现出快速的固化,具有优异的粘性,承受水分,化学品,影响疲劳。选择等级具有非凡的韧性,耐用性,耐热循环,高剥离和裂解强度,没有冷冻的长储存稳定性。产品很长必威app对于成本效益,高批量生产,促进复杂形状,大面积的粘合。预制件可以预先切成复杂的形状。即使在狭窄的债券线宽中,切削刃膜粘合剂也会在满足极端的环境条件下验证。值得注意的是,主债券胶粘剂对许多航空航天制造公司的竞争优势给予了竞争优势,并通过消除浪费来减少费用。

主债券为航空航天应用提供专门的包装,包括预先测量的套件和方便的枪涂抹器。
