[Heng Guang Xiang LED dedicated three anti-paint Product performance LED dedicated three paint as a single component light yellow transparent liquid silicone resin prepared from imported polymer compound. LED special three anti-paint can effectively isolate the circuit board, and protect the circuit from the harsh environment of erosion, destruction. Good adhesion, low stress, no corrosion of components, products, wide temperature range, high softening point of the film. Acid, alkali, salt and other chemicals has good stability, prevent leakage, anti-fog, anti-fungal, anti-moisture excellent performance, and film-forming properties quickly, thereby improving the reliability of the circuit board, increasing its safety factor, and to ensure its life. Widely used, can be formed on the circuit board lasting and excellent "three" coating to ensure long-term use in a variety of complex environments in good condition, replace the waterproof glue and other products. This product is RoHS compliant LED dedicated three anti-paint [Use] is widely used in a variety of electronic components, hybrid integrated circuits, IC chips, automotive electronic control panel, electronics circuit boards, printed circuit boards, computer control panel, industrial control panel , has assembled circuit boards, circuit boards and other semiconductor crystals. Mainly used in various types of power supplies, adapters, chargers, LED, automotive, aerospace, marine, small transformers, instrumentation, precision instruments, carrier communications, electronic components, machine protection, protective and positive.

Make sure to test the use, in order to confirm the suitability of your use, performance parameters can be adjusted according to customer requirements. [LED special three paint brush operating Treatment Process: Direct dispensing or brush, in the course of such concentration is too large, it can add thinner, special diluent availability of Division I, can dilute our environmentally friendly diluting agent, pay attention to stir. Thinner adding volume, low viscosity conformal coating of thin painted; Conversely, three anti-paint high viscosity, the thicker painted. Diluent is added in an amount of 30 to 50% recommended. Spraying process: glue diluted into the watering can, you can spray, spray wash after using thinner watering. Dipping process: glue diluted dip into the bucket, make dipping, circuit boards or components should not be immersed in speed too fast to avoid air bubbles. At room temperature for 10-30 minutes dry time is not recommended for heating and drying; When used again after dipping, if the phenomenon of surface crust, remove the skin, you can continue to use. [LED special three anti-paint Packing and Storage] packaging specifications for 5L, 18L, while demand packaging, storage should be placed in a cool, ventilated, dry coffers, prohibit open flames, direct sunlight, the storage period of 6 months.
