Other notes:

A. The coating should not be in contact with the oily substance in the solvent.

 

B. It is best to apply the original liquid when spraying the paint. If necessary, use an appropriate amount of distilled water.

 

C. The working surface should be free of dust, oil and other dirt to obtain a good spray effect.

 

D. Storage temperature 18~25 °C.

 

E. It can be stored for 6 months, absolutely avoiding the stirring action to avoid necrosis and agglomeration of the paint.

 

F. Stir the paint evenly before use and filter with 100~150 mesh.

 

  Product Specifications

 

  Product Series:

 

  LTP-8000 bottom

 

  LTP-9025 face

 

  Water-based double-layer PTFE coating

 

  product description

 

  LTP-8000/9025 coating is a water-based two-layer coating made of polytetrafluoroethylene and polyamide-imide.

  

  Product Usage

 

  It is suitable for the spraying of the inner wall of die-cast aluminum cookware; it is also suitable for the coating of the inner wall of stretched aluminum cooking utensils such as electric hot pot, teppanyaki, frying pan, etc. It can also be used for the surface of metal parts which are often rubbed on the bottom of electric iron.

  

  certified product

 

  Certified by FDA, ROHS, Reach, LFGB and GB11678-89

  

  Construction Conditions

 

  1, before the paint spraying

 

  (1) Stir the paint thoroughly before spraying. However, care should be taken not to apply high shear forces to prevent emulsion condensation of Teflon.

 

  (2) Filter with a 100-mesh filter before spraying.

 

  2, substrate pretreatment

 

  Before coating, the substrate needs to be degreased (deoiled) and sandblasted (80-100 mesh corundum). Please ensure the uniformity of sand blasting to improve the bonding between the coating and the surface of the substrate.

 

  3, spraying

 

  The coating process is as follows:

 

  Spray primer - → 140 ~ 160 ° C / 8min drying - → cool to room temperature - → spray topcoat. (Note: the top coat should be sprayed before the wet film is wet.)

 

  Spraying construction conditions:

 

  (1) Working pressure: 3.0-4.0kg/cm2

 

  (2) Distance: the spray gun is 15-25cm away from the workpiece

 

  (3) Coating thickness: primer dry film 18-25um (160 °C baking 8min), theoretical coating area 8-10 square / kg, topcoat dry film 10-15um, theoretical coating area 13-15 square / Kg, total film thickness is controlled at 22-28 um.

 

  4, baking plasticization

 

  (1) The workpiece with the topcoat should be sent to the baking treatment in time. Baking and plasticizing is the key process of film formation of perfluoropolymer. The main influencing factors are temperature and time.

 

  (2) The baking equipment can adopt continuous drying tunnel or fixed drying room, but all of the following conditions should be met:

 

  High enough temperature (380-390 ° C)

 

  Should set a good exhaust vent

 

  There should be no open flame in the furnace

 

  Temperature control is sensitive and adjustable

 

  (3) baking temperature

 

  The pot body temperature is 385-390 degrees, the highest temperature in the middle part of the sintering furnace

 

  (4) baking time

 

  The high temperature plasticizing section (pot body temperature 385-390 degrees) should be guaranteed for 5 minutes (maximum length can not exceed 15 minutes), depending on the material, thickness and size of the workpiece, the specific baking time should be based on the actual situation, the operator can pass the appropriate Adjust the transfer speed of the drying tunnel to adjust the baking time.

  

  Storage and transportation

  The storage environment should be kept ventilated and dry to prevent direct sunlight, and the fire source should be isolated and kept away from heat. The storage temperature is 5-25 ° C, and when the summer temperature exceeds 30 ° C, the temperature should be lowered.When transporting, it should be protected from rain and sun exposure, and should comply with the relevant regulations of the transportation department.

  

  package

  Packed in 20L plastic drums, 20kg/barrel.

  

  Health and safety

  Please pay attention to the warning sign on the packaging container. Use in well ventilated conditions. Avoid swallowing or inhaling paint mist. Avoid skin contact. If paint spills on the skin, immediately wash it with a suitable detergent, soap and water. When splashing into the eyes, rinse thoroughly with clean water and seek medical attention immediately.
