Fine grade powders that are blended for perfect performance. Good saturation and a medium set up time allows each tech plenty of time to press the product into place with minimal brush work. The Vicki Peters powders when used with the EMA liquid monomer are bubble free and less ratio sensitive which make them easier to work with. The recommended application brush size for EMA liquid is an #8 or #10 and a #7 flat for Odorless liquid.
