COTSHELL RESIN (POWER) & CATALYST PF LIQUID SHELL SYSTEM

Advantages
1. Significant reduction in cure cycle.
2. Excellent sand flow ability with high resistance to peel back.
3. Increased transverse strength due to improved cure through.
4. Increased build up with improved cure through.
5. Improved cure depth and uniformity of cure at identical pattern temperature and cycle times offers potential for reducing cycle time.
6. Low dilation of moulds and cores.

Storage guidelines
Avoid extremes of temperature during storage.

Safe handling
