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.

Mistron® 303 is a high-purity, functional additive ideal for adhesives, caulks, mastics, and sealants. It provides reinforcement for improved mechanical properties and imparts hydrophobicity and barrier properties for improved corrosion resistance. It is mainly composed of talc (hydrous magnesium silicate), chlorite, dolomite, and magnesite. The product is odorless and has a white or off-white to light gray color.

ACCESS® AminoKomplex Proprietary diamino-functional silane blend is a high-performance silane coupling agent designed to enhance the adhesion of coatings, adhesives, and sealants. This proprietary blend of diamino-functional silanes has a unique structure that provides improved bonding capabilities with various substrates, including glass, metal, and plastics. It is especially effective in applications where high-performance is required, such as in the automotive and aerospace industries.

ACCESS® AminoKomplex Proprietary diamino-functional silane blend

Boratherm™ H5 F13.0 is produced from a carefully selected, naturally occurring, platy, sedimentary mineral that predominantly consists of partially hydrated magnesium-calcium carbonate. The mineral’s platy particle shape and sub-micron particle size make Boratherm™ H5 products an effective rheology modifier in aqueous suspensions and other fluids. Boratherm™ H5 F13.0 is stearic acid surface-treated Boratherm™ H5 to render the surface hydrophobic. To guarantee a consistent product quality for the Boratherm™ H5 grades, the chemical composition of the raw materials, the product particle size of the final products, and the treatment process (in the case of the Boratherm™ H5 F13.0) are closely monitored and kept within a narrow variation.

Boratherm™ H5 F13.0

Access Rudolf Organosilane AE 301T1 is an excellent coupling agent that improves the adhesive and cohesive strength of coatings, adhesives, and composites. It is compatible with various solvents and resins and is especially useful for glass fiber reinforced plastics. AE 301T1 is also suitable for use in electronic applications.

Mistron® 100-100DT2 is a high-purity, platy talc with more than 97% talc content. Mistron® 100 is used for pitch control in all types of pulp and paper mills. Mistron® 100/100DT2 is also available in compacted form to improve flow characteristics and minimize dusting.

Mistron® 100-100DT2

Portaryte® B15 is produced from carefully selected, very white, naturally occurring baryte. The standardized quality of Portaryte® is guaranteed by means of an ISO 9001-certified quality management plan. The chemical composition of the raw material and the finished product is closely monitored, and the particle size is kept within a narrow variation. Fine grades of Portaryte® fillers have been specially developed for powder coating applications. They are successfully used as an alternative for fine synthetic blanc fixe in high-gloss applications.
