![]() The powder is usually a copolymer (a blend) of both MMA and EMA to get the best of both.Īn EMA liquid and a copolymer of EMA and MMA creates an overlay that is both flexible and tough and is as gentle on the nail and skin as such a product can be. If the powder was just an EMA polymer the resulting overlay would not be strong enough. A new set of nails has to be applied once a month for proper nail upkeep therefore, you should get EMA or get a manicure on a regular basis. The fact that there is MMA there is not a problem. If you have reason to believe that you may have been exposed to MMA, the first thing you should do is get the substance removed from your nails as soon as possible. MMA was developed for use in the dental industry. Do this in front of clients to inform them. If the product dissolves, then the acrylic product is safe, EMA. Powder on the other hand (no un intended!) is already a polymer so is not agressive to the skin. Let it harden and then let it soak in acetone to see if the product dissolves. ![]() Bonding to the nail does not need ethching. The only way to get good bonding with the nail is heavy etching to create a physical bond (the acrylic holding to the scratches)ĮMA monomer creates a much more flexible polymer acrylic and is not as agressive on the skin (although many people become sensitive to it if it is not kept away from the skin). I'll explain a little more: monomer MMA (liquid) creates a very hard polymer acrylic and is very agressive on the skin. Lovely to see you reading my book and, as already posted, you're correct!
