Instructions
Preparing: If it is a PRE-PROMOTED product, the amount of curing agent determined by field test will be slowly poured into the batching container and stirred.
It can be used in operation time when mixing evenly; if it is a non-pre-accelerating resin, solidification determined by field test will be added separately.
The quantity of agent and accelerant is slowly poured into the batching container, and the mixing is evenly used during the operation time.
With the use of ingredients, each ingredient should not be oversized. According to the size of the product, the process requirements and the temperature, the gel time is controlled.
Run out.
