| LTM10 series tooling prepregs, including LTM ® 16, are low temperature curing epoxy resins systems that can be post cured to produce tools with a service temperature of 200°C (392°F). This series of prepregs is suitable for the manufacture of small to large tools. Features & Benefits: - 2 to 6 days out life at 21°C (70°F)
- Minimum of 6 months storage at -18°C (0°F)
- Autoclave cure
- Mold tools directly from low temperature master
- Prepregs have excellent tack and drape
- Initial cure temperatures down to 20°C (68°F)
- Able to produce tools with low residual stress
- Unsupported (free standing) post-cure
- Low tool shrinkage matched to Cytec’s tooling block expansion during cure
- Low tooling coefficient of thermal expansion (CTE) matched with Cytec-supplied backing structures
- Good retention of mechanical properties up to 180°C (356°F) when fully post cured
- Long term service up to 200°C (392°F) in air
Product Variants:
LTM10: Suitable for rapid, very low temperature initial cure of smaller tools
LTM12: Suitable for low temperature initial cure of small-medium tools
LTM16: Suitable for low to medium temperature initial cure of large tools due to longer out lifeProperty data for LTM16/CF0700-32%RW; Cure cycle: 12 hrs at 60°C (140°F), 6.2 bar (90 psi); Post-cure: 15 minutes at 200°C (392°F) + 8 hrs at 190°C (374°F) Information provided by Cytec, subsequently acquired by Solvay. |
