Instructions
Please keep the container clean. The parts A and B are proportioned strictly according to the weight ratio, accurately weighed, and fully stirred clockwise along the inner wall of the container, and then allowed to stand for 3-5 minutes before use.
Adjust the amount of glue according to the operating time and amount to avoid waste. When the temperature is lower than 15℃, please preheat the A glue to 30 ℃ before adjusting the glue, easy to operate (A glue will thicken when the temperature is low); The lid must be sealed after use to avoid product scrap due to moisture absorption. When the relative humidity is greater than 85%, the surface of the cured product will easily absorb the moisture in the air and form a layer of white mist. Therefore, when the relative humidity is greater than 85%, it is not suitable for room temperature curing. It is recommended to use heated curing.
