8924B TDS-EN-R.pdf
Huitian® 8924B one-component polyurethane adhesive is a one-component, low-viscosity, black, low-odor polyurethane
adhesive. It has a fine, particle-free appearance, can be sprayed,
sanded, and easily trimmed after curing, and has excellent
resistance to water and low temperatures. It is specially used for
caulking and sealing harness holes and bonding PVC flooring.

weak alkali solutions, but is not resistant to solvents such as
organic acids, ethanol, concentrated acids and concentrated
alkalis.
Directions for Use
Huitian® 8924B is specially used for caulking and sealing of ship interiors,
decks, weld seams, pipelines, building waterproofing, and dust
proofing as well as bonding of PVC flooring. Before using the
product, it is necessary to read the Material Safety Data Sheet for
information on precautions and safety recommendations. Before using
8924B on materials prone to stress cracking, please consult with
the material supplier and perform substrate testing for
verification; 8924B is intended for experienced and professional
users only. Tests must be conducted with actual substrates and
application conditions before using the product, so as to ensure
good adhesion to and compatibility with the material.
Directions for Curing
Huitian® 8924B is a moisture-curing one-component polyurethane adhesive. Changes
in temperature and humidity will affect its curing rate; the lower
the temperature, the slower its curing rate.
Application Method
Surface Treatment
The substrate to be bonded must be dry and free of oil, dust,
grease, and other contaminants. Check whether the bonding material
is intact and free of any damage. If new or changed substrates are
involved, please contact the manufacturer for verification to
ensure reliable bonding.
Gluing
It is recommended to glue with equipment (such as pneumatic and
electric glue guns).
The optimal operating environment conditions are temperature
20~30°C, 50%~70%RH; note that the viscosity of the product will
increase at low temperatures. The open time will be significantly
shortened under high temperatures and high humidity; if the glue is
already tack-free, please do not conduct assembly and bonding.
During gluing and curing, avoid contact with chemicals containing
hydroxyl groups, amino groups, etc., which can cause polyurethane
adhesive to not cure or incompletely cure.
Storage
The unused adhesive should be immediately sealed for storage. When
used again, if there is a small amount of crust on the seal, just
remove it, which will not affect the normal use of the product.
During storage, a small amount of crust may appear at the opening,
which can be removed for normal use and will not affect the
performance of the product.
Cleaning and Removal
Uncured 8924B can be cleaned and removed with special cleaners or
other suitable solvents and tools of Huitian. Once cured, it can
only be removed mechanically. If skin on, for example, hands is
contaminated, clean up immediately with a towel dipped in ethanol
or a suitable industrial hand sanitizer. To avoid burns, do not use
solvents on skin.
Storage & Transportation
| Recommended transportation environment | Optimal environment: 5~25°C, <70%RH; avoid sunshine, rain, humidity, impact, and extrusion of packing. |
| Recommended storage temperature | 5~25°C |
| Storage environment | Cool, dry |
| Shelf life | 9 months |
If the storage environment temperature is exceeded, there may be a
risk of shortened shelf life. (Shelf life is less than 9 months at
a storage temperature of 25~35°C and less than 6 months at a
storage temperature of 35~40°C)
Packing Specification
8924B, 600 ml/cartridge.
Cautions
Keep away from children for storage.
