Surface modifying, dispersion and rheology additivesTiny amounts of an additive can make a world of difference to a coating’s performance.

BASF, the chemical company, offers a comprehensive range of additives under the brand names Efka®, Rheovis®, Viscalex® and Dispex®.

This booklet provides a comprehensive list of additives in the BASF range for Dispersion, Rheology and Surface Modification.

The products are divided into four main categories: defoamers, slip and leveling agents, dispersants, rheology modifiers.

For more detailed information on specific applications and product control please consult our marketing department or local sales organizations.

Products, processes and services from BASF enable you to create effects that add performance, protection, color and strength to your coatings.

Introduction

Efka® 2000 series

Defoamers

Efka 2000 defoamers are used to inhibit the buildup of foam and eliminate trapped air by causing the bubbles to burst. This series provides two classes of defoamers:

• Silicone-free

• Silicone containing

Efka® 3000 and Irgaflow® series

Slip and leveling agents

Efka 3000 and Irgaflow slip and leveling agents are used to reduce surface tension and remove flow disturbance like orange peel and other undesirable film characteristics. This series provides three classes of slip and leveling agents:

• Slip and leveling agents based on polysiloxane

• Reactive slip and leveling agents based on polysiloxane

• Silicone-free leveling agents

DispersantsDispersants are additives that increase the stability of a suspension of powders (pigments) in a liquid medium. They are used during the dispersion process. BASF offers several classes of dispersants:

• Ionic dispersants

• High molecular weight dispersants

• Low molecular weight dispersants

• Fatty acid modified emulsifiers (FAME)

• Universal grinding resins

Ionic Dispersants

Dispex® dispersants are tightly defined dispersants based on acrylic chemistry. Their narrow molecular weight distributions provide optimum dispersion efficiency, translating into maximum performance at the lowest possible formulation cost.

High molecular weight dispersants

Efka® 4000 series contains the high molecular weight dispersants. They are linear or branched molecules with a polyurethane or polyacrylate structure, and have molecular weights of between 5000 and 30000 g/mol. These products have pendant anchoring groups, which adsorb onto the surface of the organic pigment particles. They are also effective with inorganic pigments.

Low molecular weight dispersants

Efka® 5000 series contains the conventional low molecular weight dispersants. They are categorized according to their chemical structure as anionic, cationic, electroneutral and non-ionic. They are used mainly for heavily filled systems such as primers and surfacers for industrial and maintenance coatings.

Fatty acid modified emulsifiers (FAME)

FAME’s molecules are based upon fatty acid chemistry, having polar heads based on tertiary amines. They can be easily handled without addition of solvent and used effectively when combining water-borne colorants with solvent-borne base paints. They enable paint producers to develop universal colorants for the decorative market.

Universal resins for resin minimal pigment concentrates (RMPC)

Efka® 1000 series contains dispersing resins specially developed for the production of resin minimal pigment concentrates. They show good pigment wetting and stabilizing performance and excellent compatibility with the resins most commonly used in paints.

Rheology modifiersViscalex® range provides shear-thinning rheology to give good suspending power and sag resistance, but low high-shear viscosity for ease of application. Rheovis® range is less shear-thinning than Viscalex®, or more Newtonian in rheology. This provides the best leveling for gloss systems while avoiding spattering problems.

MiscellaneousThe Efka® 6000 series features additional product classes including conductivity agents, waxes, synergists, antigelling agents and rheology modifiers.
