Konform® SR Silicone Conformal Coating

Konform® SR provides maximum flexibility for extreme temperatures. This transparent conformal coating provides ideal protection for both rigid and flexible printed circuit boards. Cured coatings are hydrolytically stable and retain their physical electrical properties after high temperature and humidity exposure. Konform® SR will not stress delicate circuit components.

Konform SR is available in three different viscosities to match your application process:

  • Standard viscosity - 40± 5 cps
  • Medium viscosity - 60± 5 cps
  • High viscosity - 120± 5 cps

FAQ's

How do you prevent the valve from clogging up when using aerosol conformal coating?

I suggest you get into the habit of clearing the valve after every use. You turn the can upside-down and spray until it only sprays propellant. If you don’t do that, you run the risk of dried coating building up in the valve or actuator button. If in the button, you can switch it for another one and it should work. If in the valve, there may not be much you can do to save the can.

How do I figure out the shelf life of a product?

The shelf life of a product can be found on either the technical data sheet (TDS), available on the product page, or by looking on the certificate on conformance (COC). The COC can be downloaded by going to https://www.chemtronics.com/coc. Once you have the shelf life, you will need to add it to the manufacture date for a use-by date. The manufacture date can be identified by the batch number. The batch code used on most of our products are manufacture dates in the Julian Date format. The format is YYDDD, where YY = year, DDD = day. For example, 19200 translates to the 200th day of 2019, or July 19, 2019. This webpage explains and provides charts to help interpret our batch numbers: https://www.chemtronics.com/batch-codes.
