3KEIM – A MINERAL STEP
IN THE RIGHT DIRECTION

City Hall in Schwyz (CH), original painting from 1891

KEIM mineral paints were a Bavarian invention withtheir roots deep in the country’s heritage. They aresynonymous with the technical refinement and highquality, also found in other products that originate fromthis area of the Alps, kings and castles.
WATERGLASS FORMS A PERMANENT BOND
BETWEEN PAINT AND SUBSTRATE
The scientist A.W. KEIM successfully combined waterglass (potassium silicate) with inorganic colour
pigments to produce a paint, that both penetrates
and chemically reacts with the mineral substrate
onto which it is applied. KEIM becomes a part of thesurface whereas organic paints merely form a skinon the surface.
These high-quality silicate paint systems offer top
performance, durability, protection and colour
fastness that is unequalled. Buildings decorated
with KEIM in the 19th century are still in excellent
condition today. For example the City Hall in Schwyz(Switzerland) that was painted in 1891.

Today´s environmental awareness has led to increasing
demands for environmentally harmless, long lastingand high quality paints. KEIM responds to this byproviding a wide range of mineral based products.
The successful development of a proven basic concept.
KEY FEATURES OF KEIM ROYALAN– Highly durable– Breathable and water vapour permeable– Ideal moisture balance– Particularly economical– Absolutely colour stable and UV-resistant forlong lasting beautiful colours– Silicate matt surface appearance– Easy to apply and easy to refinish– Environmentally friendly– Perfectly coordinated system components

ADVANTAGES AND BENEFITSOF KEIM SILICATE TECHNOLOGY

NATURAL INGREDIENTS
Selected raw materials underlie the unique qualityof KEIM‘s silicate paints: The ideal combination ofliquid potassium silicate as binder, naturally occurring
mineral fillers and inorganic colouring pigments ensure
maximum weathering resistance and unsurpassed
durability.

CLEAN
Silicate paints by KEIM stay clean in the long term.
The combination of inorganic pigments and mineralbinding agents results in coating solutions that pairdurability with long-term cleanness. Compared topaints with conventional organic binding agents (e.g.
emulsion or silicone resin paints), silicate coatings are
antistatic and non-thermoplastic. This makes it hardfor dirt particles to adhere to the surface, for facadesthat stay clean and beautiful for a long time!

SILICIFICATION
Silicate paint systems with their typical binder waterglass (liquid potassium silicate) are based on theprinciple of silicification. Once applied the paintpenetrates the mineral substrate, such as render,
natural stone or concrete, and forms a permanent,long lasting, chemical crystalline bond.

A facade coating should last at least 20 years – interms of both appearance and functionality. That‘s nogreat challenge for KEIM paints, as they can easily
last twice as long. It is even no rarity for them tosurvive for a century. The ideal combination of liquid
potassium silicate as binding agent, mineral fillers
from natural deposits and inorganic colour pigments
guarantees maximum weather resistance andunsurpassed durability.

MOISTURE BALANCE
Breathability and water vapour permeability is themost important criterion for good moisture balance.
The extremely high permeability for water vapour ofKEIM silicate coatings is the result of a specific structureof the cured waterglass. Humidity contained in thebuilding structure may thus be released unhindered
and fast into the environment. No accumulations ofhumidity, which may lead to damages, can occur
between coating and substrate. In combination witha low water absorption, this is an optimal protection
against water and frost damages.

COLOUR STABLE
The colour stability of exterior wall paints is influenced
by the nature of the pigments and of the binders.
UV-light modifies the colourfulness of organic pigments.
KEIM paints contain exclusively high-quality, lightfast,mineral pigments. UV-light and exposure to weathering
also give rise to binder degradation in organic binders.
Microcracks form, which modify refraction and makethe colour shade of the coating appear greyer.
Mineral binders such as potassium waterglass exhibit
the greatest UV-resistance of all binders and are
moreover absolutely weather-resistant.
