A: Yes, and no. There does need to be a clean surface, and this is usually done by most surface treatments and pre-treatments. We do suggest either using a plasma or laser etch process depending on your setup and/or substrates.
A: 2-4 seconds. Timing depends on the equipment you use. Type of UV lamp and distance from lamp, time under lamp, apertures, mirrors- all of these aspects can effect timing. Generally we see a 2-4 second cure time, depending on how complex the part is.
A: When it comes to production, there are a lot of advantages for a coating compared to a PT film when it comes to performance and workability of the material.
A: Once you go over the 130 micron mark, the dielectric protection levels out. We recommend that you don’t go over 300 microns of coating thickness.
A: We suggest a 2-coat 2-cure process. Much better and consistent coverage with a 2-coat process. We have found there to be much lower levels of failure with this process. We suggest a partial cure on the first one to lower energy consumption as well as time requirements, followed by a second coat with a full cure process.
A: Application and the spray equipment used. Using different heads, as well as masking. We do suggest using a laser etch as a surface prep, as well as a way to clean off material that has been sprayed. Fixturing is also a large part of the process that can be used as a preventative measure.
A: The 85C-85RH high temp humidity testing was tested for 1,000 hours. The thermal shock testing was tested at -40 to 85 C were 50 cycles between those temperatures.
