seam, MS sealant OEM/ODM
7937D(HT9371MS) 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
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
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.
