MINEX® functional filler made from nepheline syenite is proven to offer superior color development, tint retention, and durability to a broad range of paints, coatings, adhesives, sealants, and inks. When added to paints and coatings, MINEX® provides unparalleled durability and resistance to abrasion, fading, cracking, and aging associated with both environmental and chemical exposures.


Minex

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 paints and systems requiring controlled particle top size such as Industrial OEM topcoat coats and non-conductive inks. Intermediate size grades offer ideal and uniform gloss control for topcoats, coil coats and increased inter-coat adhesion between primers and topcoats. Coarser grades offer high solids loading with low viscosity,  texture, anti-skid  and abrasion resistance in industrial floor coatings and exterior deck coatings.

DeCAL 2098 is an anionic superplasticizer that has been modified with polyacrylate to achieve maximum efficiency. It is highly suitable for use in mortars, concretes, self-leveling systems, adhesives, and grouts. Compared to conventional plasticizers, DeCAL 2098 has a significantly higher deflocculation effect, which allows it to maintain the dispersed state for longer periods.

DeCAL 2098

ACCESS® SFR OH 6,000 is a hydroxyl or silanol functional fluid with a medium viscosity of 6,000 cP. This pure fluid is ideal for use as an Anti-Structuring additive in high consistency silicone rubber and for the treatment of fillers. ACCESS® SFR OH 6,000 has excellent stability and can be used with catalytic amounts of ammonium carbonate to treat reinforcing fillers in-situ.

ACCESS® SFR OH 6,000

AFCONA 4008 is a polymeric dispersant used for the deflocculation of pigments. AFCONA 4008 is a polymeric dispersant used primarily in systems where aromatic solvents are forbidden. Compared to other AFCONA PU-grade dispersants, the viscosity reduction effect of AFCONA 4008 is not as strong (this is due to its more polar structure). However, this is not necessary a disadvantage, because not all mill bases require viscosity reduction.

AFCONA 4008

Ti-Pure™ TS-1510 is a highly efficient rutile titanium dioxide pigment that is manufactured with a revolutionary processing technology. It was designed to significantly enhance the level of processing efficiency in plastics applications, including POMB. Ti-Pure™ TS-1510 provides improved flowability, line productivity, energy, and labor efficiencies, along with low-dusting that promotes safer handling and material efficiency. It is excellent for high-temperature plastic applications requiring outstanding dispersibility and the lowest possible volatility.

Ti-Pure™ TS-1510

Portafill® H 5 F13.0 is produced from a carefully selected, naturally occurring, platy, sedimentary mineral consisting predominantly of partially hydrated magnesium-calcium carbonate. The standardized quality of Portafill® H 5 is guaranteed by means of an ISO 9001-certified quality management plan. The chemical composition of raw material and product is closely monitored, and particle size is kept within a narrow variation. Particle shape, fineness, and high brightness make Portafill® H 5 a very efficient extender for TiO2 in paint, paper, and board applications. Its platy particle shape and very fine particle size make Portafill® H 5 an effective rheology modifier in aqueous suspensions and other fluids. It is therefore valued for applications in a/o adhesives, sealants, and plastisols.

Portafill® H 5 F13.0

DeCAL 2077 is a derivative of a family of highly effective, low viscosity dispersing agent for water-borne coating systems. The product is especially suited for the dispersion of inorganic pigments. DeCAL 2077 is an ideal dispersing agent for a wide range of water-borne coatings.

DeCAL 2077

Mistron® 102 Compacted is a functional additive with high purity that is particularly suitable for adhesives, caulks, mastics, and sealants. This additive enhances the mechanical properties of these products and imparts hydrophobicity and barrier properties, thereby improving their corrosion resistance. Comprised primarily of talc (hydrous magnesium silicate), chlorite, dolomite, and magnesite, the product is odorless and has a white or off-white to light gray color.
