Royal Technology provides polymer coating service and coating equipment for waterproof coatings with Parylene nano film. Parylene coating technology is widely used in aerospace, precious relics, silicone rubber, seals, magnetic materials, MEMS, circuit boards, sensors, biomedical and other fields. Parylene-coated product can increase the strength and temperature insulation, abrasion proof, chemical resistance (diluted chemical), corrosion-resistant. Our equipment are presently being used by many large enterprises all over the world.
What is parylene?
It is a transparent and colorless polyester protective material. It is suitable for vacuum coating at room temperature, and the vacuum coating pressure is below 10-5 Torr, while the Parylene coating process is about 0.1 Torr. The thickness of the coating can be controlled between 1-100 microns. The coating is a patent developed by the United States in the early 1960s. It was first applied to the field of microelectronic components for US military printed circuit boards, aerospace and underwater launch devices, 1972 Included in the U.S. military standards in:
Micro and nano processing technology: chemical vapor deposition (CVD)
Put the powdered nano-materials into the evaporation chamber of the vacuum nano-coating equipment, and evaporate into gaseous molecules at a temperature of 150℃-180℃. Under the action of vacuum (1.0*10-2torr), the gaseous nanomolecules below 10nm enter into the cracking In the cracking chamber, the high temperature at 680°C-700°C is cracked into reactive monomers, and the active monomers and monomers are re-polymerized to form a dense and pinhole-free nano-film layer.
1.Circuit board coating
Parylene vacuum vapor phase coating can enhance circuit embedding and eliminate surface moisture, metal ions and other pollutants. The function of resistance, thermocouple and other components is not changed in the coating. Parylene coating can protect sensitive components in engineering circuits.
3. Medical Instruments:
4. LED outdoor lighting
5. Silicone Rubber Use
7.Historical Rlics, Fragile cultural relics, specimens, etc. can be reinforced and protected with Parylene to extend their life.
