Higher compatibility
& faster processing
• The excellent compatibility provides faster,
more flexible formulating, which shortens
R&D, lab efforts and ramp-up times
Manufacturers get more flexibility due to higher
compatibility and can adjust their products to their
needs faster and with less complexity.
Improved processing
• Ready for the future, due to fulfilled
VOC limits

Corrosion protection
Facts & results
For industrial coatings outstanding
corrosion protection is essential.
SILIKOTOP® products are tested in a
salty, wet atmosphere, that puts an
immense strain on materials.
They deliver a strong protection against
corrosion and prevent high-quality top
coats from spreading rust.

Weather resistance
Facts & results
Under toughest weather conditions,
SILIKOTOP® protects coatings from
damages and peeling off and therefor
ensures long-lasting quality.
The influence of UV radiation,
dampness, temperature, frost, and solar
radiation are substantially minimized.

Adhesion
Facts & results
High solids top coats require high-
performance binders to improve
adhesion on primers and diverse
substrates. This ensures durable
coatings and enduring preservation
of value even under toughest
conditions.

Elasticity
Facts & results
Industrial coatings are often
susceptible to dents and scratches.
SILIKOTOP® shows excellent
elasticity that results in superior
deformability and impact resistance.
These characteristics lead to better
tough elasticity and adhesion on
diverse materials and therefore
increase life cycles of coatings.
