Instructions for use
Clean:Clean the surface: remove the rust, dust and oil etc...
Gluing: The nozzle sleeve cut, take the glue mouth, cut into appropriate slope, using squeeze can glue gun is coated onto the construction site; pneumatic pressure recommended that no more than 0.4MPa sizing.
Curing:The parts are arranged in the air sizing, when after the formation of epidermis, from the surface to the interior of a room temperature curing, and 55% relative humidity at 24 hours, the curing depth of 2 ~ 4mm. With the extension of time, the curing depth increases gradually. The 7 day curing depth 6mm.
Attention
Keep away from children.
If you accidentally come in contact with the skin, wipe in the curing a cloth before class, and using alcohol solvent scrubbing.
If the case of contact with eyes, rinse immediately with water, and medical treatment.
Recommended for use in a well ventilated place
