Is DeoxIT® safe on plastic?
I have noticed that the spray versions of DeoxIT® have a 'regular' and a 'safe for plastics' version. I refurbish old circuit board type video games and I am interested in your product, but I don't really need a spray application. I was thinking more along the lines of the 100% DeoxIT® liquid solutions that require either drip or brush on applications. Is it the propellant in the spray cans that are potentially unsafe for plastics or is it the chemical composition of the product itself? Is the 100% liquid solution safe on plastics/circuit boards?
For the most part, all of the sprays are safe on plastics; however, there are some considerations to think about for each specific job.
In your case, if you have easy access to the areas you need to treat and do not wish to use a spray; the 100% formulation is perfect. All of the DeoxIT® 100% products are safe on plastics.
Just to clarify the differences in the sprays and help with choosing the proper one please view the following page on our web site.
Additionally, you are correct with your above statement. It is the propellant and/or carrier solvent which provides any concerns, however slight.
The regular versions of the sprays and liquids (D5, G5, S5 and F5) have a carrier solvent and/or propellant which provide a flushing action. With this action the carrier or propellant is slower to evaporate (2-3 minutes), possibly exposing the surrounding area to the solvent. We always recommend removing any excess and overspray after treatment, this helps to minimize any possible effects from occurring. Additionally we recommend performing a small test of the product prior to large scale application.
The nonflammable versions of the sprays (DN5, GN5 and SN5), have a carrier solvent that will evaporate almost instantly when sprayed. You loose the flushing action, however you gain the nonflammable attribute, prevents overspray and is also plastic safe. Again, we recommend performing a small test of the product prior to large scale application.
As with all of the DeoxIT® 5% formulations, once the carrier solvent and/or propellant has evaporated, you are left with 100% of the DeoxIT® product.
