The Key to the Rust Solution

PRODUCT

Steel structures with paint peeling off due to rust

Inorganic Anti-Rust Primer
Containing Carbon Fiber

AR-PRIMER 12.5

®

AR-PRIMER 12.5 is an advanced inorganic anti-rust/anti-corrosion primer which turns red rust into black rust on steel substrate under the control of its alkaline.

An emulsion with high interparticle bonding strength and a compound forms the strong barrier. Its film blocks water and oxygen which causes red rust.

In addition, carbon fiber is added to increase surface strength.

AR-PRIMER 12.5 is made of inorganic materials and is solvent free, so it is an environmentally and worker friendly product.

FEATURES

01　pH12.5

・Passivity on steel substrate due to alkaline film.

・Slows down corrosion speed on pH９～10+.

・Forms a stable passive layer on steel substrates over pH12.5.

02　Process Management

・The 2 color coat system allows proper and easy application.

・The different color of the 2nd coat allows one to easily see that the entire first coat has been covered adequately.

03　Surface Preparation

・ISO 8501-2:P St2

・Preparation of welds, edges and other areas with significant surface imperfections, using basic hand tools such as wire brushes and paint scrapers, eliminating costly sandblasting.

・No need to remove of previous coatings.

・Shortening the painting process

・Direct-to-metal primer on properly prepared steel or previously painted surfaces.
