Processing Guidelines
Mix components thoroughly in 1:1 ratio until uniform grey color is achieved. Use vacuum mixing to minimize air bubbles. Apply in layers not exceeding 40 mm thickness. Allow 6-8 hours curing at room temperature before initial machining, with full precision machining possible after 3 days. Use appropriate mold release agents for metal and composite substrates.
Packaging
Supplied in 10 kg packages of both resin (460A) and hardener (460B) components.
