The Scientific Name For The Substance Is Alumina Trihydrate (ATH), And Its Chemical Formula Is (AI2O3•3H2O)
Alumina Trihydrate |
When used as a filler, extender pigment, and bodying agent in
oil- and water-borne paint, Alumina
Trihydrate (also known as aluminium hydrate, alumina hydrate, aluminium
hydroxide, or ATH) has a minimal impact on the colour of the paint. This
powder, which has an 8-micron median particle size and ranges in colour from
white to tan, can be added to paint to give the paint film more transparency.
Due to its adaptability and affordability, Alumina
Trihydrate is the
most popular flame retardant in commercial coatings. It is suitable for use in
a variety of paint binders when processing temperatures are lower than 220 °C.
ATH has a low abrasiveness, is non-toxic, halogen-free, and chemically inert. Acid
resistance and smoke suppression are added advantages. At around 220 degrees
Celsius, ATH starts to endothermically breakdown, releasing roughly 35% of its
weight as water vapour. Acid resistance and smoke suppression are added

According to Coherent
Market Insights, The global Alumina Trihydrate Market is estimated to reach US$
6.5 Billion by the end of 2027.
Alumina Trihydrate slows down burning by acting as a
heat sink, delaying pyrolysis. Moreover, the water vapour generated has the
function of neutralising harmful fumes and combustion gases. Over 100 million
tonnes of alumina trihydrate are produced annually, almost entirely using the
Bayer process. Bauxite (aluminium ore) is dissolved in sodium hydroxide at high
temperatures using the Bayer process. After the solids are heated through,
alumina trihydrate is then separated from them. After the alumina trihydrate
has been removed, the solids are extremely hazardous and pose environmental
problems.
Silver-white Aluminium
is an element that is in group 13 of the periodic table. Aluminum is a perfect
material for engineering since it is corrosion-resistant, lightweight, and
practical.
Alumina (also known as aluminium oxide or alumina) is created
from more than 90% of all generated alumina trihydrate. To restrict and lessen
the spread of a flame through a plastic, alumina trihydrate is chemically added
to a polymer molecule or mixed in with a polymer. Another application for
alumina trihydrate is as an antacid that can be taken orally to buffer the pH
in the stomach.
