How to use:
1. Weigh the desired amount of SFY-25A andSFY-25B in the ratio of 20 to 1(by weight) into a clean containerwith four times volume of the mixture volume.2. Mix the mixture very thoroughly, then vacuum to de-air.3. Apply on prototype or target. Gently pour themixture on target, avoid trapping air. Vacuum to de-air ifair is incorporated into the mixture while pouring.4. Stand at room temperature for about 18 - 24hours depends on the thickness of application.
