1.The resin includes wax but no accelerator or thixotropic agent
2. Accelerator mixed ratio :0.8%-1.5% of resin ,Hardener mixed ratio : 1.5%-2.0% of resin
3. This one resin is sensitive to sun .it maybe will curing . so avoid opening before using under strong sun .
4. Resin is 3 class dangerous liquid .anytime should be away from obvious fire
5. Shelf life is about 6 moth below 25℃ dark and cool
