01 · Uses
Uses of a flexible polyurea coating for foam
- Coating of foam furniture and cut 3D foam shapes.
- Industrial design.
- Flexible polyurea floors.
- Flexible protective coating; an aliphatic polyurethane topcoat can be added for UV and colour stability.
For coated EPS and foam shapes, see ProLine on outdoor EPS figures.
02 · Application
Application of Krypton ProLine AB 70A Plus
Mix ratio is A=1 : B=1.1 by weight (1:1 by volume). Gel time is 12 s at 25 °C and the surface is tack-free in 20 s.
Spray at 1–2 kg/m², with component A at 70 °C, component B at 75 °C and the hose at 70 °C, at 150 bar. More than 90% of the final properties are reached after one day.
