Product Description

Technical Specifications

The Techspray 2102-12S is a Fine-L Kote SR Silicone Conformal Coating. This product is ideal for moisture and thermal vibration protection. It is the most universal coating, offering protection for a wide range of environments. It comes in a 12 oz aerosol spray can.

Techspray offers a variety of coating formulas to match field and engineering requirements. Specifications generally depend on the type of protection needed: e.g. thermal, moisture, and static resistance. Coatings contain Opti/Scan to allow quality control inspection of coverage and evenness of the coating on a PCB. A coated board can be passed under a standard, low-cost UV (short-wave black) light, and the coated areas glow. The brighter the glow, the thicker the coating.

Instructions: Surface to be sprayed should be thoroughly cleaned with solvent such as Flux Remover G3 (1631). Surface must be completely dry before application of coating. As you spray or brush coating, allow material to flow around components. Coating will be tack free in approximately 60 minutes; however, full cure requires 72 hours depending on humidity and thickness of application. Coated boards can be reworked by applying soldering iron directly to coating, or complete removal can be achieved in 1 to 3 hours by using Conformal Coating Remover (2510). Removal time depends on temperature, thickness of coating, and application.

Q. Bulk Solvents / Conformal Coating: What spigot or spout do you recommend for your metal 5-gallon and 55-gallon drums?

A. Both of Techspray's 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. These can be purchased from Lab Safety (www.labsafety.com) 1A-13572 - 3/4" 1A-11329-2"

Q. Aerosols: 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 requirements. 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 soild waste at this point (not necessarily hazardous waste).

Q. Conformal coating: What types of coverage areas are to be expected with the conformal coatings in general?

A. 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

Q. Conformal coating: The "stock" products are too viscous for some applications. Are there other viscosity ranges offered or could the orgional product be diluted to the appropriate range?

A. Techspray offers "thinner" viscosity ranges as custom blends. However, each of the 3 types of coatings in bulk may be thinned with 2105.

Q. Conformal coating: When using conformal coatings in general, what causes a "milky" cure of white "foam" on the substrate?

A. 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 and make 2-3 light passes rather than one heavy pass to coat the board.
