■Usage and precautions
※Weigh A and B glue according to the specified weight ratio and put in the prepared clear
In a clean container, mix thoroughly clockwise and leave for 3 to 5 minutes before using。
※Take glue according to the use time and the amount of mixture to avoid waste. When the temperature is below 15 ° C, first heat glue A to 30 ° C, and then mix with glue B (glue A will thicken at low temperatures); The glue must be sealed with a lid after use to avoid moisture absorption and rejection.
※When the relative humidity is higher than 85%, the surface of the healing mixture will absorb moisture from the air and form a white fog on the surface, so when the relative humidity is higher than 85%, it is not suitable for room temperature curing, it is recommended to use heat curing。
※Do not cross the LIDS of AB and AB, and do not return the glue to the original container to prevent contamination of the original glue。
※This product is non-dangerous goods, but do not import and eye。
※This product has a slight irritating smell. Please wear a gas mask and anti-corrosion gloves when operating.
※In case of contact with skin, wash immediately with soapy water。
※If it gets on your eyes, wash it with plenty of water and seek medical attention immediately。 ll
※Cover at any time after each material removal to avoid moisture absorption affecting curing and performancel
※Store in a cool, dry environment that is not easy for children. When using this product in large quantities, use it in a well-ventilated place.
