How to use?
It is a quick-drying adhesive, with short curing time and strong stickiness. After curing, the mica tape is dry, soft, and will not stick. Solvent: toluene, xylene
1. Glue concentration: 18~20%
2. Amount of curing agent (BPO or DPP): 1.0-3.0% The surface curing cycle: 60~90℃ 1min, 120~150℃ 3min
3. In order to ensure the mixing of the curing agent and the adhesive, first dissolve.
The Curing agent completely in the solvent and then add it to the glue solution, stir and mix well.
