Description: CYFORM 777 is a proven, high-performance and cost-effective, low-temperature-curing epoxy tooling system available with either carbon or glass reinforcement. CYFORM 777 allows high-quality tooling laminates to be produced directly from a low-temperature master model. After vacuum bag/oven or autoclave processing for the initial cure, the tool laminate can be de-molded and post-cured “free-standing”. CYFORM 777 is supplied in roll form with a standard roll length of 25 yards (25 meters). Standard material width is 50 inches (1000 – 1270mm). Materials are shipped frozen and in insulated boxes. Features & Benefits: - Provides versatile low temperature curing options from 48 hours at 122°F (50°C) to 3 hours at 194°F (90°C)
- Manufactured to ensure uniform resin distribution in fabrics with <1% volatile content
- Formulated for long term thermal oxidative stability during normal 350°F (177°C) service
- Exhibits low and predictable shrinkage with both carbon and glass fiber reinforcement
- Closely matches the thermal expansion coefficient of composite parts reducing dimensional inaccuracies and residual stress levels
- When used with a surface gel-coat, produces tools of extremely low void content via vacuum-bag-only processing if autoclave facilities are not available
- Determined safe to use via extensive toxicological screening (contains no MDA or VCHDs)
Suggested Applications:- Tools used for manufacture of composite components where a balance of working time and low temperature cure capability is required
