(A) Product
introduction
This product is
made of polytetrafluoroethylene and polymer binder as main materials, and mixed
with high efficiency curing agent, film forming agent, etc. It has excellent
high temperature resistance, wear resistance, lubrication and high adhesion. It
can be applied to the surface of alloy aluminum, alloy copper, stainless steel,
iron and other base materials. The coating film has the functions of
temperature resistance, wear resistance, lubrication and self repair of micro
pits.

(F) Operation
guidance
1. Substrate
surface treatment
(1) Degreasing:
the oil stain on the workpiece surface and the gap must be removed.
(2) The substrate
needs to be sandblasted (using about 100 mesh quartz sand), and the surface
roughness should reach 40-60 microns.
(3) Use compressed
air to blow away sand and dust on the surface of the substrate. If it is
necessary to soak or clean with solvent, the surface liquid must be air dried
or dried.
(4) Put the
workpiece into the oven for preheating, control the temperature at 50~80 ° C,
and keep it warm for more than 30 minutes for spraying.
2. Spraying
equipment Before using the spraying equipment, it is necessary to thoroughly
clean relevant equipment, such as spray guns, spray pots or paint cans. The
recommended cleaning process is as follows:
(1) Thoroughly
clean the equipment with the thinner matching the original paint to remove the
residual paint and residue inside.
(2) Use special thinner
or other soluble solvent to clean the equipment repeatedly (cleaning for more
than 2 cycles).
3. Preparation of
paint
(1) Dispersion:
Before using the coating, stir for 5-10 minutes, add appropriate diluent as the
case may be, and then test its viscosity to make the coating liquid disperse
evenly.
(2) Filtration:
The paint entering the watering can must be filtered with 100 # filter screen
to remove the solids that may be mixed in, so as to avoid blocking the gun or
forming particles on the surface of the workpiece.
(3) The paint
shall be adjusted when it is used. The prepared paint shall be used up at one
time during construction.
4. Painting
The spray gun with
a nozzle diameter of 1.0~1.5mm is selected, and the spraying pressure is
2~0.3MPa (2~3kgf/cm2). During spraying, the distance between the nozzle and the
substrate is controlled to be 15~30cm.
5. Drying and
curing
Keep the
temperature at 80 ° C for 20min and 230 ° C for 30min.
6. Cooling mode
After the film of the workpiece is solidified, it can be cooled by furnace
cooling or air cooling.
Please note that
the uncooled film is in a soft film state, not easy to touch and collide, and
does not have the said properties.
(G) Precautions
1. The workplace
must be well ventilated.
2. During the use
of the coating, the container containing the coating shall be covered with a
lid and sealed for use and storage.
3. This product
may be unstable when the temperature changes. Please store the product at 5-30 ℃, and gently stir or shake the product at
20-30 ℃ regularly (about 1 month) to prevent
sedimentation and condensation.
4. During normal
spraying and back spraying, the surface of the workpiece must be sprayed and
wetted without drying.
(H) Storage
conditions
1. Avoid direct
sunlight under the temperature of 5~30 ℃, and the shelf life is 6 months (unopened).
2. Package
specification: 1kg, 5kg.
(I) Waste
discharge
1. It is
recommended to use thinner to clean the spray gun, spray irrigation and
equipment. The washed thinner can be filtered and stored for use when the paint
viscosity is adjusted next time.
2. Do not
discharge the paint and its cleaning residue into the waste water system, but
store it in a specific container and treat it professionally according to local
and national environmental protection laws and regulations.
(J) Emergency
treatment
1. In case of
leakage or spillage, wash it with plenty of water.
2. If the product
accidentally gets into the eyes, immediately rinse with plenty of water for at
least 15 minutes. Seek medical attention immediately if you feel pain.
3. If this product
comes into contact with skin, please wash it with water and soap. If you feel
unwell, seek medical advice immediately.
4. If you feel
uncomfortable after inhaling spray, immediately transfer to a fresh air place
and seek medical advice.
