CHAR 21 is a very low VOC, waterborne, high performance intumescent coating providing a very effective fire barrier thanks to high active solids content, char strength and the use of nanofillers. Rapid development of a stable, insulating char provides effective and long-term protection to flammable and non-flammable substrates.
CHAR 21 can be used for fire protection of pre-stressed concrete and reinforced concrete structures, concrete and masonry partitioning walls and other non-structural elements. In structural resistance-to-fire applications it provides protection for up to 3 hours.
Achieves A Reaction To Fire Rating; Euroclass B-s1-d0.

Rapid development of a stable, insulating char provides effective and long-term protection to flammable and non-flammable substrates.
CHAR 21 can be used for fire protection of timber-based substrates. It achieves a Euroclass B-s1-d0 rating.
CHAR 21 has superior environmental accreditation, assessed by EN 16000 tests for indoor emissions, ISO 89011-2 tests for VOC content and carries approval from LEED, BREEAM, CAM, French VOC and more.
CHAR 21 achieves Euroclass B-s1-d0 on wood-based substrates of 10mm or more.
Achieves A Reaction To Fire Rating; Euroclass B-s1-d0.
CHAR 17 is a waterborne intumescent clear coating, providing a very effective fire barrier with fast activation at low temperature. When activated by a fire, the thin transparent film develops a coherent char particularly suitable for fire protection of flammable substrates. char 17 is used for fire protection of wood and other flammable substrates, while preserving their natural appearance.
CHAR 17 achieves Euroclass B-s1-d0 on wood-based substrates of 10mm or more.
Why Char 17 should be paired with Char 17 Finish Top Coat:
Char 17 is a reactive product, and while it provides vital fire protection, it is not designed for long-term exposure to weather or mechanical wear. The Char 17 Finish Top Coat is specifically formulated to protect the base Char 17 layer from:
Moisture and humidity
Mechanical damage
Using the top coat ensures the durability, aesthetic finish, and long-term fire performance of the system. It’s essential for projects where the intumescent layer is exposed or needs a decorative finish without compromising its fire-protective function.
CHAR 17 achieves Euroclass B-s1-d0 on wood-based substrates of 10mm or more.
