Eco-Stencil RF is an effective nonflammable drop-in replacement for isopropyl alcohol (IPA) and other solvents commonly used in rinse-free batch stencil cleaning systems. Unique solvent and DI water blend is effective at removing a wide variety of pastes and adhesives. Higher concentration can be used for more difficult pastes and adhesives.
Eco-Stencil RF does not contain ionics, and will not leave contaminants that will change downstream process windows or lead to board failures. It can also be used as a manual and under-stencil cleaner.
Eco-Stencil RF batch stencil cleaner has been tested and proven compatible with every part of your stencil — from the frame, screen and stencil to the adhesives binding it together.
Eco-Stencil cleaners are fully compliant with CARB (California Air Resource Board) requirements. Also compliant with European REACH (Registration, Evaluation, Authorization & Restriction of Chemicals) and WEEE (Waste Electrical and Electronic Equipment Directive) initiatives. They do not contain RoHS (Restriction of Hazardous Substances) restricted substances, SVHC (Substances of Very High Concern) list substances, or halides.

Can I use purified water instead of deionized water to dilute Eco-Stencil RF?

“Purified” is a bit of a general term, so let me break apart the potential issues: 1) Distilled water shouldn’t be a problem. 2) Reverse osmosis filtered water may or may not be a problem depending on the water source. Some dissolved minerals could conceivably get through, and minerals are generally going to be ionic. 3) Ionic contamination is probably not going to be an issue for stencil printing itself. It is migration and cross contamination that you need to worry about. If you are using rosin or water soluble flux and are cleaning your boards anyway, it is probably ok to have some contamination. If you are using no-clean flux and are not cleaning your boards, it is better to stay with distilled or DI water. 4) Minerals could conceivably affect how the paste releases from the stencil surface and build up as deposits. This wouldn’t be my top concern, but a potential risk.

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 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:
