Issue 6/2020 - Specially structured calcium silicate helps eliminate snail marks in architectural coatings

Snail marks are a challenge
for almost all architectural coatings.
Unlike manufacturers, who carefully screen the ingredients of their formulations to prevent the development of snail marks, the Evonik coating additives team takes a completely different approach to eliminating these snail marks
.
Evonik has introduced the new ZEOFREE^®600 additive, which is added during the paint preparation process or after to prevent the appearance
of snail marks at the source.

ZEOFREE^®600 additives are composed of special, porous structure of calcium silicate, small particles like sponges, absorbing and retaining water-soluble components, so that rainwater does not wash away any substances, making the façade as bright as freshly painted
.
ZEOFREE^®600 is suitable for all matte paints from white to dark colors, and the recommended dosage is 1%~5%
depending on the formulation.
The additive is a non-hazardous product and complies with the EU Ecolabel 2014/312/EU standard
