EDAPLAN Dispersants for Pigments and Fillers

EDAPLAN covers polymeric dispersants based on acrylic ester, olefin and fatty acid copolymers for water-based, universal, solvent-based and 100% solids systems, plus EDAPLAN LA leveling agents. Polymeric dispersants reduce grind viscosity and shorten dispersing times.

EDAPLAN 395: anionic, low foam tendency
EDAPLAN 396: VOC-free, for laked azo pigments
EDAPLAN 397 GR: renewable drop-in for 397
EDAPLAN 480: solvent free dispersant

METOLAT Wetting Agents Against Craters and Poor Flow

METOLAT covers mostly wetting agents and some dispersants, siloxane-based or siloxane-free, nonionic or ionic. They reduce surface tension without harming inter-coat adhesion and address craters, fish eyes, orange peel and cissing. The manufacturer lists 35 grades.

METOLAT 1299: silicone-free leveling
METOLAT 285: wetting agent or defoamer
METOLAT 344: penetration of wood coatings
METOLAT 367: VOC free per 2004/42/EC

TAFIGEL Rheology Modifiers: HASE Acrylics and PUR HEUR

TAFIGEL synthetic rheology modifiers include anionic associative acrylic (HASE) and nonionic associative PUR (HEUR) thickeners. Acrylic AP grades work in alkaline media, while PUR grades serve paints, plasters, adhesives and printing inks. The manufacturer lists 27 grades.

TAFIGEL AP 10: alkaline pH above 8
TAFIGEL AP 17: silicate paints, pH up to 12
TAFIGEL AP 18: hydrolysis stable, pH up to 13
TAFIGEL PUR 52: solvent-free PUR thickener

CERETAN Waxes for Powder and Wood Coatings

CERETAN waxes are produced by spray micronization, giving spherical particles with a narrow size distribution and a specified d99 maximum particle size. They enhance anti-blocking, slip, gloss, rub and mar resistance of printing inks, powder and wood coatings. The manufacturer lists 29 grades.

CERETAN MBP 00125 GR: stable up to 200 °C
CERETAN MA 7020: matting of powder coatings
CERETAN MA 7250: antiblocking and slip agent
CERETAN MBP GR: biodegradable, OECD 301F

Wax Dispersions and Emulsions: LUBA-print, SÜDRANOL, WÜKONIL

LUBA-print covers water-based and solvent-based wax dispersions for scratch, rub and abrasion resistance, matting and slip. SÜDRANOL emulsions combine polyethylene, oxidized polyethylene and paraffine waxes. WÜKONIL wax emulsions from the Elsteraue plant serve paints, plasters and concrete curing.

LUBA-print 280/F: drop point approx. 81 °C
SÜDRANOL HD 35: very hard HDPE wax
WÜKONIL KN 50: concrete after treatment
Elsteraue: over 10,000 t of wax emulsions

Choosing a Defoamer by pH, Viscosity and System

The polysiloxane emulsions AGITAN 150 and AGITAN 155 can be used between pH 6 and 11, while the alkali and acid resistant AGITAN 271, 350 and 351 cover a pH range between 3 and 12.

AGITAN 290 was developed for polyvinyl alcohol solutions and highly acidic media down to pH 0.5; it is silicone-free and ashless and works from room temperature up to 95 °C. AGITAN 230 and AGITAN 265 have low emulsifiability in water and suit medium to high viscosity systems, whereas AGITAN 282 emulsifies easily and suits clear coats, non-pigmented and low viscous systems.

Non-aqueous industrial lubricants take FOAM BAN 130B to 169, synthetic and semi-synthetic metalworking fluids take FOAM BAN 1820 and 1839.

Choosing a TAFIGEL Thickener by Rheology Profile

A more newtonian profile gives leveling, high gloss and brush drag, a strong pseudoplastic profile gives sagging resistance and sprayability, and medium pseudoplastic polyurethane thickeners create a universal profile for brush, roller and spray application.

Acrylic TAFIGEL AP 10, 11, 15 and 16 work in low to high PVC systems above pH 8. TAFIGEL AP 17 is designed for pH up to 12 and silicate-based interior and exterior wall paints, while AP 18 is hydrolysis stable up to pH 13.

Aqueous gloss paints with TAFIGEL PUR 45 show minimal pseudoplasticity similar to solvent borne systems; PUR 52 and PUR 54 are low viscous, solvent-free grades.

Matching Dispersants and Wetting Agents to Pigments and Defects

VOC-free EDAPLAN 396 targets laked azo pigments, phthalocyanine pigments, transparent iron oxides, titanium dioxide and carbon black. EDAPLAN 397 is a non-ionic dispersant for organic pigments suitable for coatings with indirect food contact, and EDAPLAN 397 GR is its renewable drop-in.

EDAPLAN 470 and 472 suit aqueous and solvent-based systems and binder-free pigment concentrates.

Craters, fish eyes and orange peel are addressed with METOLAT wetting agents: silicone-free METOLAT 1299 and 288 support leveling of low viscosity systems, METOLAT 344 increases penetration of wood coatings, and METOLAT 388 prevents flocculation after long storage of the paint.

Choosing a Wax by Delivery Form and Purpose

CERETAN MBP powder waxes with a narrow particle size distribution keep their particles dimensionally stable up to 200 °C, are readily biodegradable per OECD 301F and are microplastic free; CERETAN MA 7020 is a matting and degassing agent for powder coatings.

Liquid wax comes as LUBA-print dispersions: LUBA-print 352 gives slip and scratch resistance in high gloss solvent-based can and coil coatings, and LUBA-print 280/F with a drop point of approx. 81 °C gives slip and hydrophobicity in waterborne lacquers.

SÜDRANOL HD 35 based on very hard HDPE wax suits water based overprint varnishes and flexo inks, while VOC-free WÜKONIL emulsions provide open time, hydrophobicity and wet scrub resistance in paints and plasters.
