We can now offer a very fast curing silicone circuit board coating - Momentive ECC 3050S
The product is a moisture-curing silicone varnish which, at normal room temperature, cures as quickly as today's "fast" varnishes (about 30 minutes), but for ECC 3050S the curing process can be speeded up considerably by raising the temperature. The lacquer can be fully cured in 2 minutes.
Of course, the product has UL approval, UV indicator, etc. it is also a good work environment-friendly alternative to the solvent-based varnishes available on the market.
Selectively coating printed circuit boards with a protective coating is a fast and economical method for large production runs. It is also a good method if moulding is too expensive or too heavy.
A good PCB coating should have high surface insulation resistance, low viscosity, good dispersion and perfect adhesion to the substrate. Silicone-based coatings fulfil all these requirements.
Silicone circuit board lacquer has also been shown in tests to provide better protection of circuit boards against, among other things, corrosion caused by condensation than conventional coatings, especially in a saltwater-rich environment. For outdoor products, silicone is probably the best option for climate protection.
Tribotec sells polymer type PCB coatings - i.e. they cure and are completely solvent free. A polymer also provides better adhesion than a resin. They are all very fast curing.
Depending on the size of the series to be produced and the speed of production, we have several different lacquers to choose from. All are solvent-free.
Moisture-curing: TSE399C, TN3705, TSE3991CU, ECC3010, ECC3050S, ECC3020H
Thermosetting: ECC4865
UV-curing: RTV 800-260
We have long experience of helping customers find the best possible product for moulding electronics in terms of dimensions and performance requirements, and it is best when we can help give tips on how to design the product for painting.
