COMPREHENSIVE
PIGMENT PORTFOLIO
Imerys is the global leader in the supply
of high quality white pigments for the
world’s paper industry.
With a unique and comprehensive portfolio of kaolins, calcium carbonates and talc,
our global customer base is able to receive advanced multi-pigment solutions as filler
additive, coating pigment or processing aid.
Kaolin is a hydrated aluminum silicate crystalline
mineral formed over millions of years by the
hydrothermal decomposition or weathering of
granite. One of the most abundant minerals on
earth, it is characterized by its fine particle shape
and chemical inertness. IMERYS is the world’s
largest producer of high quality kaolin.
Precipitated Calcium Carbonate is produced
through a chemical reaction process that utilizes
calcium oxide (quicklime), water, and carbon
dioxide. The reaction produces very pure calcium
carbonate crystals and water. The crystals can be
tailored to a variety of different shapes and sizes,
depending on the specific reaction process used.
Ground Calcium Carbonate is composed of the
crystalline mineral, calcite, which occurs naturally
in the form of chalk, marble or limestone. Chalk is
usually fine textured, and varies in color from
deposit to deposit. Marble deposits are limestones
changed by crystallization under conditions of
extreme heat and pressure. In some cases, this
natural process yields pure marble of exceptional
whiteness.
Talc is a hydrated magnesium silicate used in the
pulp, paper and board industry as a filler and to
control pitch and stickies which clog machines
impacting runnability. It is an effective coating
agent in rotogravure and offset papers where it
improves runnability and the quality of the
finished paper. In certain specialty papers such as
colored papers and labels, its special properties
improve quality and productivity.
CUSTOMER DRIVEN
INNOVATIVE SOLUTIONS
The combination of our unique pigments and the extensive application knowledge
of our technical specialists is fundamental for the paper maker. By working closely
with customers, we are able to offer cost-effective pigment solutions that also add
real value to the finished paper.
Imerys has developed a platform of platy clays
from Middle Georgia with large plate diameter and
thin crystal dimension that can deliver unique value
in a variety of paper grades.
These clays were developed with patented technology and are available in a range of
particle sizes and shape factors. Their extreme shapes allow them to interact more effectively
with blockier particles such as calcium carbonates in order to provide bulkier structures with
optically effective pore sizes, improved coating hold out, better coverage and significant cost
savings.
E-500 and E-800 are premium coarse pigments specifically
designed to provide coating coverage and build coating
bulk in precoating or low gloss applications. They work
especially well when blended with blocky co-pigments such
as ground calcium carbonate. The improved coverage can
allow papermakers to reduce calendering and thus mprove
sheet bulk, or apply lower top coat weight.

Contour Extreme HS, E-160 HS, E-270 and E-300 are
premium fine platy clays developed for a variety of
applications. They can work well in single coating LWC
applications or can also be used in pre-coat applications
when blended with blocky co-pigments. The improved
physical coverage can allow the papermaker to change fibre
source, reduce coat weight or increase carbonate share in
the recipe. The mproved optical coverage through the
structuring with carbonate can enable reductions in base
bleaching, reduction in coating opacifiers or reduction in the
white top fibre layer in packaging grades.
