3. Suggestions for use:
This resin is not pre-promoted resin, because of the processing process and processing product characteristics, resin inherent gelation time drift characteristics, whether to add accelerators, users have their own test before use.
4. Note:
1) This product will solidify due to self-aggregation when heated. Store in a cool and ventilated place, avoid direct sunlight exposure, and avoid contact with oxidants. The shelf life is 1 month at 25ºC. The shelf life will be shortened when the storage temperature is increased or the sunlight is direct.
2) Because there are many factors in the processing process that affect the performance of resin, it is necessary for users to conduct their own tests before use. And the company reserves the right to modify the above technical data when necessary.
