Teflon high-performance special coating is a fluorine coating based on Teflon resin, the English name is Teflon, because of the pronunciation, it is usually called Teflon, Teflon, Teflon, Teflon and so on (all for the translation of Teflon).Teflon (teflon) coating is a unique high-performance coating that combines heat resistance, chemical inertness, excellent insulation stability and low friction. It has comprehensive advantages that no other coating can compete with. The flexibility of its application enables it to be used in almost all shapes and sizes of products.
Teflon can be divided into PTFE, FEP, PFA and ETFE.
Teflon PTFE, PTFE (polytetrafluoroethylene) non-stick coating can be used in 260 ℃, the highest temperature 290-300 ℃, low friction coefficient, good wear resistance and excellent chemical stability.
Teflon FEP: FEP (fluorinated ethylene propylene copolymer) non-stick coating melt flow during baking non-porous membrane formation, has excellent chemical stability, excellent non-stick characteristics, the highest temperature is 200 ℃.
Teflon PFA: like FEP, PFA (perfluoroalkyl compound) nonstick coating melts and flows during baking to form non-porous film.PFA has the advantage of continuous temperature 260 ℃, has higher stronger GangRen degrees, especially suitable for use under the condition of high temperature resistant glue and chemical resistance to use areas.
Teflon ETFE: ETFE is a and tetrafluoroethylene ethylene copolymer, the resin is the most tough fluorine polymer, can form a layer of highly durable coating has excellent chemical resistance, and can work continuously under 150 ℃.
After teflon coating, it has the following characteristics:
1, non-viscous: almost all substances are not with teflon coating adhesion.Very thin film also shows very good nonadhesion performance.
2, heat resistance: teflon coating has excellent heat and low temperature resistance.Resistant to high temperature to 300 ℃, short time average between 240 ℃ ~ 260 ℃ can be continuous use, has significant thermal stability, it can work under freezing temperature and not brittle, not melt at high temperature.
3, sliding: teflon coating has a low coefficient of friction.The friction coefficient changes during load sliding, but the value is only between 0.05 and 0.15.
4, moisture resistance: teflon coating surface is not stained with water and oil, production operation is not easy to touch the solution, if there is a small amount of dirt, simple wipe can be removed.Short down time, saving time and improving work efficiency.
5, wear resistance: under high load, with excellent wear resistance.Under certain load, it has the double advantages of wear resistance and non-adhesion.
6, corrosion resistance: teflon is almost free from drug corrosion, can protect parts from any kind of chemical corrosion.
Product packaging specification: 20KG.
Coating appearance: transparent light.
Film hardness: higher than 4H, depending on the choice of substrate, the highest 9H.(ordinary teflon coating is only higher than 2H)
Coating glossiness: 40 -80 (spraying operation is very important, too thick surface will become rough)
Typical use or base material, note :(aluminum, stainless steel, ceramics, cold plate iron, cast iron, mold metal, etc.)
Paint effect: highlights.
Color: transparent, silver, grey, black, etc.
Proportion of coating: 1.2
Coating solids: 40%1%
Coating viscosity (1) : 100-350CPS
Coating coverage: about 10 m2 / kg
Preparation before substrate coating: in addition to oil, sandblasting (can use emery 60 to 80 mesh) (no sandblasting equipment can be directly roughened after spraying).
Coating filtration: over 100 mesh filtration.
Paint drying and sintering temperature: preheat the substrate 50-60 degrees before spraying (can also not preheat), baking constant temperature of 280 degrees about 15 minutes.Rise slowly to 280 degrees, or it may cause peeling of the coating
Film thickness: 20-25 microns
A. Spray with compressed air. Water must be removed before spraying
B. Shake the bottom sediment evenly before use
C. During spraying production, protective measures should be taken to avoid inhaling fog generated during spraying process
D. Spray gun must be cleaned after spraying (alcohol)
Notes for curing at room temperature:
1. This product is a single component, which can be automatically cured at room temperature. The surface drying time is 30-60 minutes, and the complete curing time is 24-36 minutes
, the temperature has a significant impact on the curing time, the temperature is high curing fast.
2. This product can only be put into use after fully curing.
3. The cover should be closed immediately when using to avoid curing of the product due to prolonged contact with air.
4. Operate and use tools. Equipment should be clean and dust-free.
5. Pay attention to ventilation and fire prevention at the operation site.
