Tolsa Reports Growing Use of Fireproof Additives
Tolsa SA, a Madrid-based supplier of specialized additives
for the paints and coatings industry, has reported a growing
use of its ADINS Fireproof additives for intumescent
paints and coatings applications. ADINS Fireproof delivers
exceptional flame-resistant performance for a range of
intumescent coatings systems including vinyl toluene
acrylics, styrene acrylics, silicone acrylics, fluoropolymers,
epoxies, urethanes, and chlorinated rubber.
" We've seen widespread
acceptance of our ADINS
Fireproof solutions, particularly
in intumescent coatings where our
environmentally friendly additives
provide strong flame- retardant
performance, " said Dr. Antonio
Esteban, Tolsa's chief research and
technological innovation officer.
Intumescent coatings are special formulations that
act as a protective barrier against fire. Most recently,
customers have experienced positive results with the use
of ADINS Fireproof. There is demand for intumescent
coatings in specialty coatings sub-segments such as marine,
transportation, onshore/offshore oil and gas production, and
new industrial and commercial construction. Intumescent
paints are increasingly used to protect spherical structures
containing natural gas, peroxides, and other chemicals.
Most noteworthy, in new construction of commercial
buildings, intumescent coatings incorporate flame-retardant
chemicals to achieve two distinct industry efficacy ratings.
The first measures flame spread, or how effectively the coating
limits flammability (according to ASTM E84). The second
rating demonstrates coating efficacy for delaying and resisting
the effects of fire.
ADINS Fireproof materials are ceramifying additives based
on a natural silicate activated with phosphate compounds.
The modified silicate has a low melting point glass. ADINS
Fireproof synergists are used in combination with a broad
range of flame-retardant additives. Depending on the nature
of the coating, the recommended Fireproof grade is different,
but there is an ADINS Fireproof additive for each coating
formulation.
These additives also deliver a range of performance benefits
including improved thermal stabilization, creation of a heat
barrier to protect the surface from burning, reduction of
the emission of organic flammable volatile compounds, and
reduction of oxygen penetration into the decomposition zone.
ADINS significantly reduce the rate of flame spread on
the surface of a material to which it has been applied. They
also resist ignition when exposed to high temperatures and
insulate a substrate to which it has been applied (ASTM D 16).
Fireproof additives are composed of more than 70 per cent
natural ingredients. They are an environmentally friendly
solution for paint applications still complying with standard
regulations.
