We can now offer a silicone hardboard lacquer ECC3020H. It is a completely solvent-free paint, with low viscosity and fast curing at room temperature. What's new is that it gets really hard - 85 shore A after curing. This provides good scratch resistance while still being flexible enough to protect components during thermal expansion. It's completely unique.
Silicone coatings for printed circuit boards are generally quite soft and flexible. However, some customers have requested a hard and smooth surface to easily wipe off accumulated dust. This is exactly what the ECC3020H fulfils. To top it off, it is UL 94 V-0 rated.
The paint is developed by Momentive Performance Materials, and is the latest addition to our portfolio of solvent-free coatings. Like all silicone coatings, it offers superb protection against humid environments and has a very wide working temperature range: -55°C to +200°C.

NEW No 2!
ECC3020H is available in aluminium bags! The bag can be lifted out of the bucket and put into a pressurised chamber. This way you can pressurise with compressed air, which is a cheaper investment than using a bucket pump. The bags have a tap that can be connected directly to the dosing equipment.
PCB coating is an economical and smart way to protect sensitive electronics. Read more about our circuit board lacquer here.
