Epotec® Tooling Systems allows to manufacture custom build tools for specific uses. The precise composite tools can be made in most complex shapes quickly and easily. These tools offer low thermal expansion and provide excellent strength to weight ratio. Wide range of service temperature, ranging from -170 to +220 °C and easy handling of Epotec® Systems made them suitable for lay up molds, bonding fixtures, check fixtures, drill and assembly fixtures.

YD535LV /
TH7255 | 100 : 35 | 500 - 750 | 25 - 35 | 80 - 90 | Low viscosity, fast cure system. | YD535LV /
TH7256 | 100 : 35 | 500 - 650 | 80 - 100 | 80 - 90 | Slow reactive, low viscosity system for fairly large molds. | YD535LV /
TH7278 | 100 : 25 | 700 - 1,000 | 50 - 70 | 80 - 90 | Low viscosity, moderate pot life system for medium size molds. | YD535LV /
TH7295 | 100 : 30 | 800 - 1,200 | 120 - 140 | 110 - 120 | High temperature resistant low viscosity system for slow curing. | YDL660 /
TH7455 | 100 : 25 | 1,500 - 3,500 | > 16 hr | 170 - 200 | Very high heat resistance, extra slow hardener, post curing required above 150°C for full strength. | YDL670 /
TH7353 | 100 : 22 | 1,000 - 2,500 | 1 - 3 hr | 130 - 180 | Excellent heat resistance, post curing above 120°C is required. | YDL690 /
TH7455 | 100 : 25 | 3,000 - 6,000 @ 50°C | > 16 hr | 220 - 240 | Suitable for tools used above 200°C. Long post curing above 200°C is essential to achieve optimum strength. |
