Polymers are produced by polymerisation of monomers like acrylates, styrene, maleic acid or other unsaturated substances.
The SMA-resins (styrene-maleic anhydride) of the Erkarad-series distinguishes itself with a broad compatibility with solvents and other resins. The products with high acid numbers can be solved in water after neutralization and therefore they are recommended for aqueous applications.
There are soft as well as hard polymers for different applications available. As combination resins they are used for lacquers (e.g. NC, aqueous, overprint, stoving or paper lacquers) as well as dispersion paints, solvent based or aqueous printing inks and temporary varnishes.
