CLARCEL products are obtained by flux calcinationand particle size selection of diatomite.

They are composed of more than 85% of silica

Diatomite main properties

Diatomite is a mineral composed of the amorphous silica skeletal remains of microscopic aquatic plants called diatoms.

Matting effect

To obtained a matt effect small particles (5µm to 50µm) are added to paints.

The irregular and very porous shape of diatomite enhance their efficiency.

A narrow size distribution is however necessary to insure regular roughness of the surface and reflection of light.

Paints are more than just colors we apply to surfaces.

They are coatings serving a variety of purposes.

In addition to coloration, paints protect surfaces,can change their shapes, and alter their physical properties.

Let's consider paints as coatings

Paints as coating

Permeability

JL/Mkt Paint 10/05 V1

Most paints include at least four groups of components:

Binders, Volatile substances, Pigments, and Additives.

Binders give their structures to paints.

They create coatings that stick to surfaces and remain in place indefinitely.

Volatile substances are chemicals that keep the paints fluid enough to be applied easily and that subsequently evaporate during drying.

Pigments give coating its color, opacity, and other optical properties

Additives help these three components working together to form a uniform coating.

Some additives aid in the drying process

Others help keep the binder or pigment particles from clumping together before the paint is used

Still others alter paint’s viscosity to make it easy to apply.

A performant solution :

Paints must meet two requirements :

Common paint problems

Excess humidity or other moisture escaping from inside through the exterior walls

Penetration of rain, humidity and other forms of moisture

The water is unable to escape through the paint and create blisters when the paint is heated by sunlight.

Rainwater migrates through wall and gets under the layer of paint.

Permeability

Act as a barrier to rain

First requirement

Permeability

JL/Mkt Paint 10/05 V1

The film does not allow rainwater to pass into the wall because the capillaries in the film are much finer than those in the wall.

Second requirement

Allow the release of any moisture contained in the substrate or coming up from the ground by capillary action.

Permeability

JL/Mkt Paint 10/05 V1

The micro porous nature of the paint, plus its excellent adhesion, allows moisture in the wall to pass through the paint without blistering.

Solution : Breathability

The micro porous nature of paints means that they protect the masonry surface from rain, allow entrapped moisture vapour to escape.

• Preventing the penetration of water, but enabling the removal of moisture

• Minimum surface preparation

• Easy to apply, even on complex surfaces

• All weather application

• Excellent dry film properties that provide adhesion, durability and breathability.

How do we get Porosity

JL/Mkt Paint 10/05 V1

Porosity

The structural porosity of Diatomite CLARCEL®

☺ Helps the dispersion of the components

☺ Helps the drying process by improving the liberation of solvent or water from the surface

☺ Allows the migration of moisture to avoid bubbles in the film of paint

What about the market of Masonry Paint

In Western Europe, Brteathability is a key parameter for Masonry paintsThis is measured according to ISO NF 7783-1

Chemically inertCLARCEL do not react with the solvents and is environmental friendly.

WhitenessCLARCEL products have an extremely good regularity of the whiteness (single extraction site).

HardnessBecause of the hard silica structure, CLARCEL improve the resistance of the surface to scrub.

Silica structureCLARCEL allow internal light reflection leading to plain colours with less pigment.

LOW DENSITY compared to Calcium carbonate (< 600 g/l) or Talc (> 400 g/l)

� Lower sedimentation rate => better stability

� Better uniformity => particles spread better in the coating
