7931 MS sealant is a silicon alkyl terminated polyether as a main
component, low viscosity, general type of one component moisture
curable sealant. Curing material combines the advantages of
polyurethane and silicone adhesive sealant products, is a new
Preliminary fixed the sealing of joints, such as weld seam sealing,

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
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.
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
