Acrylic airbrush thinner
There I happened to be one sleepless evening cruising through YouTube video clips and I occurred across a topic that caught my eye - making your own personal acrylic thinner. For years we used Isopropyl Alcohol (99percent) that one can find cheaply in drug stores, but this required really serious air flow because the alcoholic beverages vapor will get soaked up quickly into the bloodstream as you breath it (not good). I had excellent outcomes utilizing alcoholic beverages as an acrylic slimmer for paints from Tamiya, Gunze Sangyo (Aqueous/Mr.Hobby), Vallejo, Italeri, and Akan (don't try this with Testors Acryl, it took time to completely clean the resulting goo from my airbrush). Utilizing liquor ended up being fine when I ended up being solitary, but making use of alcohol today will get some less-than-polite feedback from my wife.
I discussed this with a few knowledgeable folks who thin their acrylics with water (or windshield washer fluid). The few times I attempted liquid had been enough to hold myself on the alcohol road (feels like W.C. Fields, doesn't it?). I have been using Tamiya acrylic slimmer which includes worked fine currently (excluding Testors Acryl) but between price and supply, it had been becoming difficulty. That is once I saw this YouTube movie from Genessis Models in the UK. He recommends a fascinating combination that merited a test.
There are four components:
- Distilled water
- Isopropyl Alcohol (99.9%)
- Acrylic Flow Improver
- Acrylic Fluid Retarder
The guy into the movie advised a variety of 33% alcoholic beverages to 67percent distilled liquid. Distilled liquid does not have the contaminants/additives found in regular water or well liquid. I personally use 99.9% Isopropyl Alcohol given that cheaper strength alcohols are not as effective (in accordance with the people that taught myself the alcohol strategy years back) and is also recommended into the movie. The 3rd ingredient is a few falls of Acrylic Flow Improver to eliminate surface stress associated with fluid (you might have been aware of individuals using a drop of dish detergent for the same function). The ultimate ingredient is Acrylic Fluid Retarder which slows down the drying time of acrylics and keeps your paint in liquid form with regards to strikes the design and does not dry on airbrush tip or perhaps in the air enroute to the model.
We constructed an assortment of water and alcohol using the proportions above, then included around 10 ml of Flow Improver and 10 ml of Fluid Retarder for this test batch. With a recent test build, I used Tamiya, Italeri (Vallejo), Gunze Sangyo Aqueous (Mr.Hobby) and Akan acrylics, all thinned with this specific blend. The paint responded well out-of my airbrush. I did try several shots of acrylics straight-out of their containers to look at difference in overall performance. There clearly was indeed a big change! The resulting slimmer blend smells a comparable as Tamiya's thinner although you'll nonetheless want to use some air flow, this thinner is a lot more family friendly than pure alcohol and more efficient (for me about) than clear water. The best part is that you can adjust the proportions of every of the four ingredients until such time you find that perfect mix.
I didn't use this combination for airbrush cleanup when I utilize Windex screen cleaner with ammonia for the task. The Windex does not thin the acrylics, it dissolves them and working Windex through the airbrush does not keep any nasty smells (but if your spouse does enquire about the odor, tell this lady you are cleaning the room).
What exactly about expenses? A gallon of distilled liquid will operate you around $1 USD within supermarket. 99.9% Isopropyl Alchohol can be seen for approximately $3 USD/pint (473 ml). I tried to obtain the Acrylic Flow Improver and Fluid Retarder on regional art offer shops but We ended up buying all of them from Amazon. The Flow Improver cost about $12 USD for 250 ml therefore the liquid Retarder about ten dollars USD for 118 ml. We utilized a 500 ml bottle for my mixture and calculating the expense of products, it are priced at about $2.65 USD to mix 500 ml and I have actually ample liquids which will make more batches. Comparison this with a 250 ml bottle of Tamiya X20A thinner for nearly $9.00 USD.
