Anticorrosion heat resistant compositionALUMOTERM
|
Description
One-package composition based on organosilicon high-temperature varnish and aluminum powder.
| |
Destination and fields of applications
Anticorrosion protection of metal articles and constructions, acting for a long period of time at temperature up to 350 °Ñ (for a short-term up to 400 °Ñ) in all atmospheric environments according to ISO 12944-5:2007.
Is used in complex protection systems as a top coat upon coatings ZINOTERM.
Certification, testing
The sanitary-and-epidemiologic finding ¹ 66.01.10.231.Ï.003050.08.06 dated 28.08.2006.
Approbated by the Russian River Register.

Reccomended condition of the painted surface
The undercoat should be cleaned of dust and dirt, degreased with water based detergents (solvents are not applied) and dried up.
Application method
- The composition is to be thoroughly shuffled up to homogeneous state before using;
- If necessary it is to be diluted by solvent to operating viscosity.
- The composition can be applied in plant and field environment at temperature from -15 °Ñ to +40 °Ñ and relative air humidity 85 %.
The composition ALUMOTERM is to be applied in 1-2 layers, with total thickness not more than 30 micron, on the coating ZINOTERM after it’s dried up to “pull-of” state. Exceeding nominal thickness of the coating may lead to decrease of heat-resistant behavior of the coating.
Drying up of the coating is natural. Final composition of the coating is in the issue of thermo- cure at the initial stage of the articles using (heating is at temperature 150 °Ñ during 3 hours).
