What are Pergopak® organic matting agents?
Pergopak® flatting and matting agents are organic thermoset polymethyl urea resins (PMU) offering significantly different performance advantages and benefits versus typical silica and polypropylene type flatting agents. They help formulators of industrial coatings, inks and overprint varnishes achieve a higher-performing balance of low gloss, rheology, abrasion resistance, coin-marking, water resistance, chemical resistance, heat resistance and soft feel.
A voluminous powder of low bulk density, Pergopak® has an excellent degree of whiteness resulting from an almost 100% reflection over the entire ultraviolet and visible wavelength range. Primary particles, with an average particle diameter of 0.1 to 0.15 μm, form nearly spherical agglomerates of 3 to 9 μm. These agglomerates have a relatively high specific surface area and pore volume. Because of this special structure, Pergopak® products achieve distinguished matting effects compared with other nucleating agents for polypropylene.

Huber Advanced Materials is an expert in the development of matting agents.
Pergopak® matting agents provide high matting efficiency for paints and varnishes. Thanks to their chemical nature and structure, Pergopak® matting and effect agents can be used alone or in combination with other matting agents in a variety of coating formulations. The result: surface properties and visual and physical effects that standard matting agents like silicas or waxes simply cannot deliver.
The four Pergopak® matting and effect agent grades provide a high performance balance of matting, clarity, rheology and abrasion resistance along with a pleasant feel. As thermoset polymers, they provide advantages in the overall resistance of the coating due to their hardness and non-melting properties. Pergopak® grades can be used in air-dry, baking and two component systems, including water-based, solvent-based and UV curing systems.
