Turbo-­Coat Acrylic Conformal Coating is designed to speed up board production throughput without additional investment of expensive UV systems or other capital equipment. Conformal coating cure time is often considered a production bottleneck for PCB assembly operations. Turbo­Coat (standard viscosity) dries tack­free in 3 minutes, allowing manufacturers to handle boards in 1/3 the time of the leading acrylic coating! Full cure can be achieved as quickly as 10 minutes with elevated temperatures.

Acrylic conformal coating is recognized for its high dielectric strength, and fair moisture and abrasion resistance. What generally distinguishes acrylic coating from other resins is ease of removal. Acrylic coatings are easily and quickly removed by a variety of solvents, often without the need of agitation. This makes rework and even field repair very practical and economical. 

Turbo-Coat comes in 2 viscosities:
Standard - 10-20cps
High viscosity - 52-60cps

FAQ's

What solvent can I use to thin this conformal coating?

Turbo-Coat Thinner (part #2110) can be used as a thinning agent.

How do you apply liquid conformal coating? (2109)

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 9 minutes.  Full cure requires 15 hours @ 74˚F (23˚C). Heat cure: 55 minutes @ 131˚F (55˚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 Conformal Coating Remover. Use TraceTech™ Conformal Coating Remover Pen for spot removal. After the new component is installed, areas should be cleaned and re-coated.

Cure:  Room temperature cure: A 1.0 mil coating will be tack-free in 3 minutes.  Full cure requires 15 hours @74˚F/23˚C. Heat Cure: 30 minutes @149˚F/65˚C.

Use TraceTech™ Conformal Coating Remover Pen for spot removal. After the new component is installed, areas should be cleaned and re-coated.

How do you use an aerosol conformal coating? (2108-12S)

Shake well. SURFACE MUST BE CLEAN & MOISTURE FREE. Areas not requiring coating should be masked. Coating:  Spray top to bottom, allowing coating to flow around components. Rotate board 90˚ and repeat process 2 or more times.  If nozzle clogs, clean with solvent or use new nozzle. Cure:  A 1.0 mil coating will be tack-free in 3 minutes.  Full cure requires 15 hours @74˚F/23˚C. Heat Cure: 30 minutes @149˚F/65˚C.

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 properly dispose of an aerosol can after it is empty?

It may be different state-by-state, so contact your state environmental agency for regional specific regulations. For a general guideline, here is the process according to EPA hazardous waste regulations 40CFR. The can has to be brought to or approach atmospheric pressure to render the can empty. Puncturing is not required, only that it “approach atmospheric pressure”, i.e. empty the can contents until it’s no longer pressurized. This insures that as much contents as is reasonably possible are out of the can. It is then considered “RCRA-empty”. At that point it can be handled as any other waste metal container, generally as scrap metal under the recycling rules. Note that the can is still considered a solid waste at this point (not necessarily hazardous waste).

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.techspray.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.techspray.com/batch-codes.
