Konform® LED Silicone Conformal Coating

Konform® LED is a silicone conformal coating designed for light emitting diode (LED) applications, where a completely transparent coating is required to provide a tough, protective coating. Ideal for LED lights, displays and controls, especially when used in outdoor or other extreme environments. Konform® LED provides maximum flexibility for extreme temperatures on the flex and rigid circuitry found in LED displays. Cured coatings are hydrolytically stable and retain their physical electrical properties after high temperature and humidity exposure.

FAQ's

How do you apply liquid conformal coating? (CTSR-X, CTLED)

Apply to clean, moisture-free surface.  Areas not requiring coating should be masked. Application: Coating may be applied by spraying, brushing, dipping or flow coating.  Allow coating to flow around components. Cure:  Room temperature cure: A 1.0 mil coating will be tack-free in 30 minutes.  Full cure requires 24 hours @ 77˚F (25˚C). Heat cure: 30 minutes @ 90˚F (32˚C) then 100 minutes @ 199˚F (93˚C). An open vessel of water placed in the drying chamber will facilitate curing. UV detectable for QC inspection. Removal:  Coating may be removed by soaking in Electro-Wash® Two Step Cleaner Degreaser. Use CircuitWorks® Conformal Coating Remover Pen for spot removal. After the new component is installed, areas should be cleaned and recoated.

When using conformal coatings in general, what causes a "milky" cure or white "foam" on the substrate?

In almost all cases, the cloudy or milky cure comes from coating in higher humidity conditions. The white foam (from an aerosol) is caused the same way. We have the following suggestions: 1) If possible, allow the substrate and coating material to come to approximately the same temperature when applying. 2) Avoid applications in RH > 60%. High humidity ranges will discolor some coating resins and will start curing others. Besides the aesthetic value, it certainly may affect adhesion to the material. 3) Specifically on the silicone coating, if the resulting application is foamy, increase the focal point of the can, ie back off to about 10 -12” from the substrate & make 2 -3 light passes rather than one heavy pass to coat the board.

What types of coverage areas are to be expected with the conformal coatings in general?

Wet film thickness = Sq. ft. per gal. | 0.1 mil = 16,040 | 0.5 mil = 3,210 | 1 mil = 1,600 | 2 mil = 802 | 3 mil = 535 | 4 mil = 401 | 5 mil = 321 | 6 mil = 267 | 7 mil = 229 | 8 mil = 201 | 9 mil = 178 | 10 mil = 160

What spigot or spout do you recommend for your metal 5-gallon and 55-gallon drums?

Metal 5-gallon and 55-gallon drums are compatible with standard 3/4" and 2" spouts. Ideally use 3/4" for 5-gallon, 2" for 55-gallon.

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.
