M1 STARDUST varnish - FUHS44 Is a shiny and colorless solvent-based polyurethane varnish.

Our Intumescent Fire Retardant Varnish is intended to promote fire protection, retard the spread of flames, and limit the temperature rise of the material.
Its reaction to fire is excellent since it does not feed the flame
Its resistance to fire and high temperatures limits the spread of a fire.

Our varnish complies with the NF P92-507 standard, it is classified M1 non-flammable
Conditions of validity of the approval,
- when applied to raw material, as indicated in the certification, the approval of the varnish is validated on a non-insulating M0 support.

Features
Transparent, colorless, hard and glossy finish
Two-component type (our offer includes the hardener)
Coverage from 6 to 10m² depending on the support and the thickness
VOC < 420g/L
Mixture: By weight, 100 parts clearcoat, 33 parts hardener
Application: gun or roller
Thickness: 25 to 50 µm dry
Application: French building
Dilution possible with all lacquer or PU thinners
Dry to the touch: 60 min / through in 24 hours


Fire standards and European classification

In the field of fire resistance, we speak of the German type of combustibility and flammability.
Combustibility is the amount of heat released during the total combustion of the material
Flammability is the amount of flammable gas given off by the material

In the field of fire safety, we distinguish between 2 main concepts which are "reaction to fire" and "resistance to fire".
European standards define and regulate its characteristics Specifically:

"Reaction to fire" Represents the material as a potential fire fuel (combustibility, flammability), and is defined by the M rating
The different materials (concrete, wood, paper, etc.) will behave differently as fuel for the flame. (Test according to Standard NF P. 92.507)
5 levels of reactivity are established, from non-flammable material (M0) to the most easily flammable material (M4)

Fire resistance Refers to the duration during which a material can retain its properties
physical and mechanical, during its ignition, or a fire

*The classification of our M1 varnish is established by a specialized test laboratory. It gives rise to a fire classification report.
In practice, a material that has an M4 classification will ignite very quickly and will promote the rapid spread of flames.
On the contrary, a material classified M0 can hardly ignite and cannot spread the flames.

Stardust also offers a varnish that meets the fire classification "Euroclass" whose codification goes from A to F

TEST
Brief description :
Date: 07/11/2022 validity 5 years
Substrate: Fiber cement 6mm 1800 kg/m3 representative of any non-insulating M0 support
Type of test: NF P 92-501 - Radiation test
Test report reference:
Minutes No. DO-22-4281A-R1
Company: CREPIM

The M1 classification corresponds to the fire protection standard valid in Europe

What is the M1 class fire classification?


M1: combustible (non-flammable)

M2: combustible (fireproof)

M3: combustible (moderately flammable)

M4: combustible (highly flammable)

REMINDER of European standard EN 13 501-1:


M0 = A1; A2 s1 d0 Euroclass: Non-combustible
M1 = B s3 d1Euroclass: Non-flammable * excluding flooring
M2 = C s3 d1 Euroclass: Fireproof
M3 = D s1 d0 Euroclass*: Moderately flammable
M4 = D s3 (d1) Euroclass*: Highly flammable
