917 TDS-EN-R.pdf
Huitian® 917 polyurethane adhesive is a one-component, black, low-viscosity, high-strength, low-odor
polyurethane adhesive. After curing the adhesive layer is
elastomeric, with good resistance to changes in temperature and
stress. The product is suitable for manual gluing.

Chemical Resistance
Huitian® 917 is generally resistant to fresh water, seawater, weak acids and
weak alkali solutions, but is not resistant to solvents such as
organic acids, ethanol, concentrated acids and concentrated
alkalis.
Directions for Use
Huitian® 917 is suitable for assembly and bonding of windshield glass of
engineering machinery cabs, cars, ships, etc., as well as bonding
and sealing of some metal structural parts.
Before using the product, it is necessary to read the Material
Safety Data Sheet for information on precautions and safety
recommendations. Before using 917 on materials prone to stress
cracking, please consult with the material supplier and perform
substrate testing for verification; 917 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® 917 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. Thoroughly clean the new glass and
body paint coat with 8902, and check whether the bonding material
is intact and free of any damage. If new or changed substrates are
involved, please contact Huitian for verification to ensure
reliable bonding.
Primer Application
Apply primer to the cleaned substrate surface with a primer
applicator. Start gluing after the primer evaporates and dries.
Before application, a primer agent suitable for the actual
substrate and application conditions should be selected according
to Huitian's primer program. Then apply the primer according to the
primer application requirements.
Gluing
It is recommended to glue with equipment (such as pneumatic and
electric glue guns or equipment with pumps). In order to ensure a
uniform thickness of the bonding layer, it is recommended to form a
triangular adhesive shape (as shown in Figure 2).
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 917 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 the 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 the 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
300 ml/cartridge; 400 ml/cartridge
Cautions
Keep away from children for storage.
If the eyes are accidentally exposed to the product, rinse
immediately with water, and seek medical attention.
It is recommended to use the product in a well-ventilated place.
Please consult the MSDS of the product for safety information.
Waste Disposal
If not polluted by other substances, the waste can be stacked in
landfills in principle and will not pollute water quality. Since
the product can be burned, the waste can be disposed of in a waste
incineration plant. Undoubtedly, it is necessary to abide by the
environmental regulations of the local government.
Health and Safety Information
Before operating this product, it is necessary to get familiar with
its hazards, proper use and disposal, and other relevant
information. The following information may be useful: Material
Safety Data Sheets (MSDS) and product classification marks. For
more detailed information, contact your sales representative or
technical service representative.
