Performance Minerals ExtendersFor Coatings and Inks

BASF Performance Minerals Enhance Coatings and Inks

Performance minerals solutions from BASF can deliver

• Increased profitability

• Improved processing efficiency

• Improved performance and appearance

• Controlled rheology

BASF's broad line of performance minerals are produced in state-of-the

art processing facilities, where service and quality are key components

of every product offering. We also provide technical and logistics sup-

port, as well as product development collaboration.

In addition to being the

world's leading chemical

company, BASF is also a

world-leader in surface

and materials science

and a foremost supplier

of high-value perform-

ance materials for more

than a century.

Kaolin

Kaolin is most commonly associated with

titanium dioxide extension; However, it is

engineered to perform as a multifunctional

extender that simultaneously addresses a

wide variety of formulation needs.

BASF kaolins in coatings applications can

provide:

• Formulating flexibility

• Titanium dioxide extension

• Increased opacity and tint strength

• Sheen control

• Stain resistance

• Improved holdout

• Brushing ease

• Mud-crack resistance

• Color pigment extension

• Pigment suspension

• Rheology control

• Low VOC capabilities

Architectural Coatings

High brightness, ease of dispersion, controlled

particle size distribution, low specific gravity

and platy morphology make kaolin a value-

added component in flat, eggshell, semi-gloss

and high-gloss paints.

Interior Flat Paints

In water-borne and solvent-borne interior

paints, kaolin adds value by providing titanium

dioxide extension (ASP® 170 , ASP NC)

improved opacity and tint strength (Ultrex®

96 and Satintone® products), sheen control

(Mattex® and Mattex MX), color pigment

extension (ASP 170), washability and stain

resistance (ASP NC) and scrub resistance

(Satintone W).

Exterior Paints

In water-borne and solvent-borne exterior

paints, kaolin positively impacts tint reten-

tion (ASP 400 and Satintone W), gloss

retention (ASP 170) and one-coat coverage

(ASP 170). The platy structure and low oil

absorption of ASP 400 provides a low

degree of chalking, crack resistance and a

high resistance to dirt pick up.

Gloss and Semi-Gloss Paints

In water-borne and solvent-borne gloss and

semi-gloss paints, ultrafine particle size kaolin

products provide excellent titanium dioxide

extension while maintaining high gloss. ASP

G90, ASP 200 and ASP 170 kaolins can be

used in both latex and solvent-borne paints

to improve coverage at both high and low

PVC's. ASP G92 and ASP 072 products are

recommended for water-borne paints only.

Performance Minerals Solutions for Architectural Coatings

Automotive Coatings

Kaolin plays an important role in automotive electro-deposition primers by providing tank stability, film smoothness, corrosion resistance,edge film build and uniformity. BASF kaolinproducts for automotive primers are character-ized by low salts content, easy dispersion, goodthrowing power and proven performance.

Polyester Gel Coats

Kaolin improves blister resistance in unsaturatedpolyester gel coats, which protects fiberglasscomposites in products at risk of attack by water,such as boats and bathtubs. Translink® 37 surface-treated kaolin provides improved blisterresistance, better color retention, and viscosityand sag control compared to calcium carbonate,talc and synthetic silica. Satintone 5HB calcinedkaolin provides improved opacity. Studies indi-cate that kaolin also reduces gloss reduction better than other minerals additives after long-term exposure to water.

Industrial and Specialty Coatings

Kaolins are broadly used in industrial and specialty coatings:

• Traffic Paint - Satintone W kaolin offers titanium dioxide extension and abrasionresistance.

• Textured Paint - ASP 900/902 kaolins offerslow viscosity, leveling and brushing ease.

• Baking Enamels - ASP RO kaolin offersimproved adhesion, titanium dioxide exten-sion and excellent film properties.

• Coil Coatings - ASP 200 and ASP 170kaolins offer improved adhesion and titaniumdioxide extension.

Performance Minerals Solutions forAutomotive and Industrial Coatings

Hydrous kaolins are common components ofmost ink systems. Kaolin extenders for ink appli-cations are characterized by high whiteness anda tightly controlled fine particle size distribution.Hydrous kaolin is pulverized and surface treatedfor ease of dispersion, improved hydrophobicity,improved wetting and rheological control. Kaolinis a versatile ink extender that simultaneouslyaddresses a wide variety of formulation needs.

Kaolin used in ink applications can provide:

• Strike-through resistance

• Color pigment extension

• Low abrasion

• Rheology control

• Fast dry time

Offset Inks

Offset inks are applied in thin films that contain avery high concentration of pigments. Both weband sheet fed offset inks run at high speed andrequire high viscosity and tack, as well as a highresistance to emulsification from the fountainsolution. ASP 101, ASP RO and ASP 170 prod-ucts offer the best balance of properties andemulsification resistance in ink fountain solution.ASP G90 hydrous kaolin is especially suited foroptimal colorant spacing for improved opticalproperties as well as promoting high print gloss.

Gravure Inks

Compared to offset applications, gravure inkscan use more kaolin extender in the formulation.The very low abrasion and platy nature ofhydrous kaolin makes it an ideal product forgravure inks. ASP 600 kaolin provides excellentstrike-through resistance and low abrasion prop-erties and is a very good choice for gravure inks.Other grades suitable for this application are ASP200, Buca and Catalpo hydrous products.

Performance Minerals Solutions for Inks

ASP 602 kaolin, a spray-dried product is alsosuitable for this application where high shearcapabilities are available for dispersion.

Flexographic Inks

The quantities and types of kaolin extenders thatare added to flexographic inks are similar tothose used for gravure inks. For solvent-borneapplications, such as flexible packaging, the highdegree of whiteness and light scattering and fineparticle size of ASP 170 and Ultrex 96 kaolins arenecessary to efficiently extend TiO2, provideopacity and promote optimal spacing of colorantparticles. For water-borne applications, ASP 170and Satintone 5HB products provide excellentpigment extension, hiding and ease of dispersion.

Screen Inks

Screen inks are characterized by high viscosity toallow for a high film thickness. Compared togravure and flexographic applications, a thick filmis applied during screen printing to providevibrant color, opacity and longer service life.Calcined kaolin extenders provide high whitenessand light scattering. Satintone 5HB calcinedkaolin is an excellent kaolin extender for screeninks.

Specialty Inks

Kaolin extenders are also used in several types ofspecialty inks, including letterpress, security,ultraviolet curing and electron beam curing. Fortechnical advice in using kaolin extenders in anyof these applications, please contact your BASFrepresentative.
