MC400-4AB: 8-10 kg, used up in 15 minutes
At 20-25 degrees Celsius:
MC400-5AB: 10-20 kg, used up in 15 minutes
MC400-4AB: 10-15 kg, used up in 15 minutes
At 10-15 degrees Celsius:
MC400-5AB: 20-30 kg, used up within 20 minutes
MC400-4AB: 15-20 kg, used up within 20 minutes
4. Use method
1. Working environment: Please keep the plastic container clean. A, B components are strictly according to the weight ratio, accurately weighed, and stir it evenly along the inner wall of the container clockwise until it is used for 3-5 minutes.
2. According to the operating time and amount of glue deployment, to avoid waste. When the temperature is lower than 15 °C, please pre-heat the A glue to 30 °C and then adjust the rubber, easy to operate (low temperature, A glue will thicken ); After use must seal the lid, to avoid the product due to moisture absorption scrapped.
3. When the relative humidity is more than 85%, the surface of the cured product can easily absorb the moisture in the air to form a white mist. Therefore, when the relative humidity is more than 85%, it is not suitable for room temperature curing. It is recommended to use the heating and curing.
4. The lid must be sealed after use to avoid the product being scrapped due to moisture absorption.
