HUBER
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. Pergopak products help formulators of industrial coatings, inks and overprint varnishes to achieve a higher performing balance of low gloss, rheology, abrasion resistance, coin-marking, water resistance, chemical resistance, heat resistance and soft feel – that they are unable to achieve with silica or wax flatting agents alone.
MICRO POWDERS, Inc.
Micronized wax additives and surface modifiers provide a toolbox of solutions that can enhance durability, functionality, aesthetics, and haptics. They add block, rub and water resistance – important properties for graphic
arts applications. Micronized powders, micronized dispersions and emulsions of Synthetic, Polyethylene, Polypropylene, PTFE, Amide, Carnauba and New Naturally derived waxes and wax blends.
MINIFIBERS, Inc.
SHORT STUFF® highly fibrillated HDPE fibers are a unique form of polyolefin fibers having properties which offer many advantages over conventional products, such as fumed silica or cellulosics, in certain applications. These fibers can be used in coatings, block fillers, stucco, adhesives, putties, mastics, grouts, caulks, sealants, casting slurries, and more.
TOLSA
PANGEL Sepiolite & Bentonite, CIMSIL Attapulgite products are high-purity shear-thinning additives made from different clay minerals that can be used in both water and solvent-based systems. We offer products used as thickeners, providing high stability, preventing settling and syneresis, while keeping good flow and leveling properties.
PIGMENTS

ZS INTERPOLYMER
SYNTRAN® water-based acrylic grades based on proprietary technologies that can be used in a variety of paint & coatings and graphic arts/ink applications. In addition to conventional alkali-swellable and emulsion acrylics, ZS Interpolymer offers four unique acrylic technologies: dual self-crosslinking technology gives superior water, stain and chemical resistance compared to traditional self-crosslinking acrylics, anionic-cationic hybrid technology gives cationic properties with anionic compatibilities, such as tannin blocking, inherently matte acrylic technology is an acrylic-based liquid matting agent without the need for inorganic chemistry, acrylic-olefin grafting technology offers better stability than traditional olefin waxes.
FUNCTIONAL MINERALS
BURGESS PIGMENTS
Thermo Optic Flash Calcined clays, OPTIWHITE, OPTI-WHITE MX, and OPTIWHITE P, are specifically designed to lower TiO2 levels, control sheen for maximum matte effect, and improve tint strength, touch-up, and scrub and burnish resistance. Conventional calcined kaolin grades Iceberg and Icekap K offer standard filler performance properties.
An extensive range of cutting-edge and cost-effective functional performance mineral fillers and manufactured material solutions. MINEX functional filler in ultrafine grades made from nepheline syenite which provides unparalleled durability and resistance to abrasion, fading, cracking, and aging associated with both environmental and chemical exposures of inks and varnishes. They also provide improved through-cure in UV inks, allowing photo-initator reductions and lower costs. IMSIL microcrystalline silica fillers are produced from an inert, naturally occurring alpha quartz with a unique grape-like morphology. Finer micronized grades are useful in formulating higher gloss and non-conductive inks.
MAGRIS TALC
Nicron engineered microcrystalline talc products are high- purity, premium mineral pigments. Engineered talc products impart hydrophobicity, water resistance, and barrier properties, anti-corrosion performance, film
reinforcement, ease-of-dispersion, and anti-settling rheology for printing ink systems. Mistron high-brightness, high-purity talc products offer superior pigment spacing properties and flatting efficiency.
