- Instruction for Use
The individual components containing fillers should be stirred or agitated without introducing excessive air before use to ensure that all fillers are properly dispersed. To obtain the best cured properties; accurate proportioning and thorough mixing are essential.
Mix contents thoroughly each time before removing material. To each 100 grams of Epoxicast EC-1190, add appropriate amount of Hardener of your choice and mix it well preferably using a mechanical mixer. Vacuum degasses for about five minutes to remove any dissolved or entrapped air. Proceed with the bonding application and cure as recommended.
- Industrial Usage
These materials are intended for industrial use only, and the practices of good housekeeping, safety and cleanliness should be followed before, during and after use.
