7931(HT9301MS) MS sealant ,silicon alkyl terminated polyether,
sealing of joints, such as weld seam sealing
MS sealant is a silicon alkyl terminated polyether as a main
component, low viscosity, and general type of one component
moisture curable sealant. Curing material combines the advantages
of polyurethane and silicone adhesive sealant products, is a new
generation of. The operating period is long, low modulus, without
bottom coating, curing, paintable with high elasticity, resistance
to ultraviolet light and excellent weather ability. Free of
solvent, isocyanine free, non silicone, products tasteless
environmental protection.
Typical use
Applicable to the operating period is long, there is preliminary
fixed the sealing of joints, such as weld seam sealing, etc.

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.
Storage: Unused plastic blocks should be tightened immediately, to seal the
tube mouth save. Again, if sealed, a little crust, remove
immediately after, does not affect the normal use. In the process
of storage, the nozzle may also appear a few crusts, remove after
normal use, does not affect the product performance.
The matters needing 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
