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.

Pangel M90F is a magnesian bentonite-based rheological additive for easy gelling and dispersing capacity. This activated bentonite product increases stability and viscosity control with very fast dispersion. Pangel additives have been specially designed to optimize the rheology of the whole thickening system, either alone or in combination with other organic additives.

Pangel M90F

AFCONA 7466 is a highly functional polymer containing carboxylic acids, providing excellent anti-settling, anti-floating, and anti-flooding properties. It also effectively stabilizes compounds containing color pigments and extenders, and, when combined with a suitable rheology agent, it can further enhance its anti-settling capabilities.

AFCONA 7466

TYTAN™ CP-326 is a coupling agent that can enhance the dispersion of inorganic fillers in polymer systems such as PP and PE by modifying the surface of filler particles. The content of fillers can therefore be increased, saving on the cost of polymer while maintaining the mechanical property.

TYTAN™ CP-326

DeCAL 2170B is a highly efficient surfactant and versatile wetting agent. It is an aqueous/propylene glycol formulation containing the sodium salt of dioctyl sulfosuccinate. DeCAL 2170B can be post-added to a coating formulation to assist in the wetting of substrates with low surface tension, such as plastics and metals.

DeCAL 2170B

AFCONA 3581E is a silicone-based leveling and anti-crater agent for aqueous coatings that does not influence intercoat adhesion. AFCONA 3581E is the 52% effective substance version of AFCONA 3580, an organically modified polysiloxane with very short chain repeatable units of siloxane. These small molecules allow it to move very quickly to an area of defects. This offers very good anti-crater properties without causing intercoat adhesion problems.

AFCONA 3581E

AFCONA 4720 is a 100% active, solvent-free dispersion agent based on a three-block high molecular weight polymer and a group of anchoring agents. Its advanced structure allows for the development of pigment dispersions that have improved compatibility across a wide range of applications.

AFCONA 4720

Crys-Talc® 7H-7HC is a high-brightness, ultrafine, micro-lamellar talc that is recommended for nucleation of polymers and for film and thin-gage polymer applications. It significantly increases the crystallization temperature of semicrystalline polymers, including polyolefins, polyamides, and polyesters. Crys-Talc® 7H also enhances the stiffness, HDT, and dimensional stability of polymer compounds. The high brightness and micro-crystallinity of the talc ore used make Crys-Talc® 7H ideal for film or thin sheet applications that require optimum optical properties, e.g., high clarity and low haze. Crys-Talc® 7HC is the compacted form of Crys-Talc® 7H and is recommended for maximum extruder throughput, minimum dust, and improved dispersion.

Crys-Talc® 7H-7HC

Access Rudolf Organosilane A311B is a highly effective adhesion promoter that enhances the bonding strength of polymers and inorganic substrates. It is a modified version of A311 and is specially designed for bonding applications that require high-temperature resistance. The product is a clear liquid and can be easily integrated into various formulations.

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.
