Raven 405

Product Description:

Raven® 405 is a 100% solids, ultra-high build, solvent free epoxy coating formulated with exceptionally high physical properties and chemical resistance. 405 exhibits a superior bond to dry and damp concrete, masonry, steel, ductile iron and fiberglass and is specifically designed as a corrosion protection and structural enhancement lining system which can be used on and in wastewater structures, buried pipelines, tanks, and other corrosive environments.

Typical Uses:

Severe Wastewater Environment—New or existing concrete and steel structures where rehabilitation of an existing structure requires enhancement of the structural integrity and where exposure to concentrated acids and caustics may be expected. Also, designed to reduce the Inflow and Infiltration (I&I) to sewer collection systems.

Recommended thickness will vary from 30 – 250+ mils per coat based on service conditions.

Optimal proportioning and mixing is achieved with the use of a Raven Lining Systems approved plural-component airless spray system. Raven recommends the use of fixed ratio (3:1), such as, Graco XP 50 or 70 Plural-Component Pump System. Viscon Fluid Heaters and heated hoses are recommended. Carefully monitor, heating devices such as drum blankets or bands to avoid scorching of the material or melting drum liners. Pre-heating containers must not exceed temperatures greater than 150°F.

115-145°F for Part A and 90-125°F for Part B. Temperature is dependent on ambient conditions and hose lengths. To equalize viscosities and reduce operating pressure, Part A should be 20°F warmer than Part B during processing.
