Euroclasse A non-flammable clearcoat

The SUHS-A clearcoat is a glossy and colourless water-dilutable acrylic non-flammable clearcoat that meets the "Euroclasse" fire classification, whose codification goes from A to F

It is an innovative water-based aliphatic polyurethane-type acrylic clearcoat.

Our SUHS-A intumescent clearcoat is classified A2. It is recommended for fire protection classification, in particular on CE products.

It retards the spread of flames because it is non-flammable.

The product “Varnish Anti-Fire Euroclass SUHS-A” is an architectural and decorative varnish.

Fire reaction test: The M* or Euroclass classifications concern fire reaction (flammability, smoke, etc.)

CLASSIFICATION OF THE REACTION TO FIRE

Varnish Anti-Fire Euroclass (SUHS-A)

IN ACCORDANCE WITH NF EN 13501-1: 2018

Classification report number: DO-24-6202A-R1 (CREPIM Laboratory, France)

►Flame propagation, NF EN 13823+A1: Compliant
►Flaming droplets/particles: Compliant

Classification:

The product “Varnish Anti-Fire Euroclass – Reference: SUHS-A”, according to its behaviour in the event of fire, is classified A2.

Euroclass fire classification

Euroclasses are a European standardised classification relating to the reaction to fire of construction products.

> Euroclasses "A" for reaction to fire apply compulsorily to CE-marked products.

> For all other products, it is possible to choose the old M classification. We offer a class M1 fire-resistant clearcoat

There are correspondences between the Euroclasses (A to F) and the M classification (see table below)

A flammable material will ignite quickly and spread fire, while an A or M1 clearcoat or material will hardly ignite, thus delaying the fire

What is the fire resistance duration of Euroclass varnish?

For all other products, it is possible to choose the old M classification. We offer a class M1 fire-resistant clearcoat.

There are correspondences between the Euroclasses (A to F) and the M classification (see table below).

A flammable material will ignite quickly and spread fire, while an A or M1 clearcoat or material will hardly ignite, thus delaying the fire.

What is the fire resistance duration of Euroclass varnish?

The M or Euroclass classifications concern the fire reaction (flammability, smoke, etc.).

These are standards that concern cases of fire outbreaks.

The many fire resistance classifications (durability, integrity, sealing, insulation, etc.) are something different; there are specific standards applied to each material. EN1363 is the classic standard.

The fire resistance of materials is classified with the codes EI30, EI60 (sealed insulation + time in minutes).

These standards concern ongoing fires, and the tests are done above 1000°C for long periods.

This never concerns paints and varnishes.

Of course, our M class or Euroclass varnishes can be integrated into a fire-resistant system (for example, fire doors).

Resistance and reaction levels of anti-fire materials and clearcoats

In the field of fire safety, there is a difference between these 2 notions :

>>> reaction to fire, defined by the M classification: It represents the behaviour of the clearcoat or material (wood, paper, concrete) as fire fuel (combustibility, flammability). 5 levels from M0 (non-flammable) to M4 (highly flammable).

For the Euroclass classification (A is the best and F the worst).

>>> fire resistance : In a fire, it is the duration during which a clearcoat (or material) retains its physical and mechanical properties.

Euroclasses also specify two essential criteria, for which our SUHS-A clearcoat has been tested in the laboratory:

Smoke opacity (quantity and speed) from S1 (low) to S3 (high)

Flaming droplets and debris rated D from D0 (none) to D2

The classification of our Euroclass A2 clearcoat is the result of tests carried out by a specialised test laboratory (CREPIM France). It gives rise to a fire classification report.

- European decree of November 21, 2002 - Euroclass CE

the clearcoat doesn't confer any classification on its base material
