919 Polyurethane Sealant, PU sealant, interior, locomotive, ship,
919 is a single component, White, medium viscosity, high-strength,
low odor polyurethane adhesive. Touch dry and depth of fast curing
time, appearance and no particles, after curing, polishing,
painting. Can be easy to be repaired, water resistance, excellent
low temperature performance.
Seam for filling the bus interior, locomotive, ship, container,
cold storage and other parts of the.

Instructions for use
Surface cleaning: clean surface: remove the rust, dirt, water and
Sizing: cut a small hole in the beak suitable rubber barrel, glue
mouth diameter should be considered sizing width and decide, into
the glue gun start sizing operation.
Curing: a large temperature and humidity environment on
polyurethane adhesive surface drying and curing effect, low
temperature, curing slow; temperature and humidity is too high, dry
too fast. The best operating environmental conditions: temperature
20 to 30 DEG C for 50 ~ 70%RH, humidity exceeds 5 to 35 DEG C; the
temperature, humidity 35 ~ 75%RH range please careful construction.
Polyurethane adhesive in sizing and curing process, avoid contact
with chemicals containing hydroxyl, amino and, this kind of
material will cause the polyurethane glue curing incomplete.
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
Recommended for use in a well ventilated place
