Acid-dissolvable Melamine Resin Particles Back to microParticles homepage
microParticles GmbH has been sucessfully marketing acid-dissolvable melamine resin
particles. As a result of recent efforts, the accessible size range could be significantly
extended. Currently, monodisperse soluble melamine resin beads are available from nominal
500 nm up to 7 µm in diameter.
Contrary to our stock-held highly crosslinked melamine resin research grade beads, these
specialty particles are weakly crosslinked and soluble in hydrochloric acid as well as in
some organic solvents. They are characterized by excellent monodispersity and highly uniform
spherical shape. The particles possess a pH-dependent surface charge and are the most
suitable choice for polyelectrolyte coatings or as templates for the preparation of hollow
capsules.
