Looking for Multi-Etch Distributors Outside North America

We are pleased to announce that Multi-Etch is now available in Australia! Our newest distributor is Nick Hacko Fine Watches.

Besides Australia, Multi-Etch has distributors in the U.S. and Canada. We regularly get requests to ship Multi-Etch outside the U.S., including to many European countries. How we wish we could send it to everyone who asks! The problem is that even though Multi-Etch is vastly safer than the industry standard of hydrofluoric and nitric acids, Multi-Etch is still considered a hazardous material. Because of that, there is a burdensome amount of paperwork that must be completed and filed with every shipment that leaves the U.S. and for that reason, shipping expensive.

We have a minimum requirement of 100 units of Multi-Etch for shipments leaving the US. Each unit makes one gallon of regular strength or 1/2 gallon of double-strength Multi-Etch. Most of the shipping cost is due to the paperwork and required licenses associated with shipping hazardous materials. So the more product you buy, the less per unit shipping will cost.

If you are a company already selling jewelry supplies, metal-working supplies, or industrial cleaning products, contact us for how you could add Multi-Etch to your product selection.

Plastic Containers to use with Multi-Etch

We often stress the importance of using and storing Multi-Etch in plastic containers, never in metal or glass. First time users will receive dry Multi-Etch powder in a plastic gallon jug. This jug is meant to have distilled or deionized water added to make a gallon of regular strength or 1/2 gallon of double strength Multi-Etch. You can use water heated to 150ºF in the jug to mix the solution.

When using heated Multi-Etch in either a double boiler or in a custom tank, there are a number of types of plastics that can be used. For small users (one gallon or less,) you can find suitable plastic containers at big box or grocery stores. Look on the bottom of containers to see a number inside a triangle. Most of these containers will have a number 5, for polypropylene. These can withstand up to 230ºF.

For those of you building your own containers, several other plastics besides #5 can be used:

#2 white polyethylene can be heated to 150ºF. This is what our Multi-Etch jugs are made of.

#3 PVC types 1 and 2 are also an excellent choice.

#7 is usually polycarbonate and can be heated to 212ºF but #7 does include other plastics so sometimes means a type other than polycarbonate.

If you will run larger tanks of 5-20 gallons, we recommend IPEC Global who can construct complete customized systems which can include tanks for cleaning, rinsing, Multi-Etching, rinsing, and anodizing. Check them out at http://ipecglobal.com/ and see videos of their systems.

Using Multi-Etch Heated and Unheated

Ever since we developed Multi-Etch in 1993, we have always used it heated because it is much quicker than using it at room temperature. Recently we conducted extensive experiments to compare the efficacy of heated vs room temperature. What we discovered is that over time, whether heated or unheated, unused Multi-Etch solution etches faster than when it is first mixed up. But the difference takes months to notice.

We also discovered that if you heat the whole solution just one time to 150 degrees Fahrenheit, i.e., bring it to a boil and turn it off, that activates the solution and it will work much better at room temperature from then on. If you don’t have equipment to heat up Multi-Etch safely indoors, take a hot plate and a simple double boiler outside and heat it up there. Once it’s boiling or close to boiling, you’re finished! You can then use it while it’s still warm or let it cool down and use it unheated. But, it will always work faster if you can use it heated.

Etching Titanium & Other Metals

Wondering if Multi-Etch will work with your process? Or, do you need to know specific details about how to use Multi-Etch? This is the place to ask those questions and get some answers. You can start a discussion and hear what others are experiencing. We’ll address your questions and ask some of our own to get conversations going as well as post articles of interest.

Join others in the dental, medical, jewelry, aerospace, and consumer product industries who have switched from using dangerous acids like Hydrofluoric, or never wanted those hazards in their work life in the first place and chose the safe route for etching titanium and other metals.

The danger of working with hydrofluoric acid has been in the news lately following the huge explosion at an oil refinery in Philadelphia. A Reuters.com article reports:

“A source familiar with plant operations said one explosion occurred at the 30,000 bpd alkylation unit that uses hydrofluoric acid (HF), one of the deadliest chemicals in the refining business and a source of controversy for its use to make high-octane gasoline at refineries located in densely populated areas.

“Hydrofluoric acid can form a toxic cloud at room temperature, with exposure leading to severe health problems and even death.”
