filler / extender produced from high purity white Washington limestone. It is
designed specifically as a high quality filler/extender for use in paints,
plastics, and mastic systems. In paint formulations, it contributes to titanium
dioxide spacing for hiding and exterior durability. Microna 2 is also
recommended for use in rubber, reinforced polyester, and plastisol compounds.
Typical applications include:
| Paints: |
Industrial paints, brushing enamels, stoving enamels, powder coatings, and
water-thinable lacquers. |
| Plastics: |
Plasticized PVC profiles, moldings and coatings. |
| Other Applications: |
Adhesives and inks. |
Microna 3 is a fine dry natural calcium carbonate filler / extender produced
from high purity white Washington limestone. This product is specifically
designed for use in all types of coatings and paints. It provides consistent
high fineness of grind readings and good gloss development. Microna 3 is
effective as a value adding extender in rigid and Plasticized PVC, especially
in critical uses requiring the absence of impurities. Microna 3 is used at high
levels in putties, caulks, and sealants because of its nominal oil absorption.
Typical applications include:
| Paints: |
Synthetic resin paints, emulsion paints, industrial paints, and primers. |
| Plastics: |
Plasticized PVC profiles, injection moldings,
coatings
Polyolefins; Compound/master batch for moldings and films
Thermosets; EP/UP molding compounds GRP PUR-foam |
| Other Applications: |
Dry wall cements, textured finishes, caulks, sealants and inks. |
Microna 7 is a dry filler / extender pigment produced from high purity white
Washington limestone and specifically designed for use in various rubber and

Microna BP 200 is the de-dusted filler / extender pigment produced from high
purity white Washington limestone and designed specifically for building
products, particularly dry wall cements, joint compounds, caulks, sealants, and
textured paints. It is specially formulated with the ultra fines removed to
improve the performance of these end products.
All of these end use areas have several filler requirements
in common –
brightness, low binder demand, uniformity, and suitable particle size
distribution to accomplish excellent compactness and shelf life stability.
ConCarb is a de-dusted filler / extender pigment produced from high purity white
Washington limestone designed specifically for concrete and concrete ready-mix
products. Benefits of ConCarb include, but are not limited to, improved
workability, fluidity, green strength, and particle packing.
ConCarb also enhances savings through cementious content reduction, reduces
segregation and abrasion while improving fire resistance compared to fly ash
concrete.
Micronatex is a de-dusted ground limestone sand produced from high purity white
Washington limestone designed specifically for use in architectural products,
as a filler for cultured marble and in textured paints. It is specially
formulated with fines removed to improve the performance of these end products.
All of these end use areas have several filler requirements
in common –
brightness, low binder demand, uniformity, and suitable particle size
distribution to accomplish excellent compactness and shelf life stability.
Columbia River Carbonates has introduced a line of wet ground natural calcium carbonate slurries designed for use in conventional and metered size press formulations. We have appropriate ranges of particle size distributions to fit specific end-use applications. The use of Micronasize as a functional additive or simply as a technically versatile fiber substitute at the size press is a dynamic new tool for papermakers. Please consult with a CRC representative for more details.
