1). Pls clear the model and tool totally before operation to prevent cure inhibition.
2).Weigh the two part correctly by electronic weight in two separate container .
3). Mixing the two part in 1:1/10:1 and stir part A and part B evenly in 2-3 minutes .
4).And get the mixture for vacuum-pumping for de-air the bubble in around 2-3 minutes . (If there is no vacuum machine, pls pour the mixture carefully and slowly down the side of the mold frame so that less bubbles caused)
