SSPC PAINT 36
Two-Component Weatherable Aliphatic Polyurethane Topcoat, Performance-Based
|Publication Date:||1 April 2006|
This specifi cation covers the requirements for a highperformance two-component UV-stable polyurethane topcoat (ASTM D 16, Type V polyurethane). It is intended as a topcoat that provides excellent color and gloss retention, not as a thick-section elastomeric coating.
Coatings meeting the requirements of this specifi cation are generally suitable for exposures in environmental zones 1A (interior, normally dry), 1B (exterior, normally dry), 2A (frequently wet by fresh water, excluding immersion), 2B (frequently wet by salt water, excluding immersion), 3B (chemical exposure, neutral), and 3C (chemical exposure, alkaline).
The specifi ed coating is intended for application by brush, spray, or roller. It is generally applied over a primer or intermediate coating.
