In General
Ebalta MG 321 FR-S is processed on a two-component low pressure device.
After grinding with a sand paper , grit 280, the surface can be varnished with a commercial lacquer. For better adhesion we
recommend the use of a primer coat. Nitrocellulose lacquers have a better adhesion on polyurethane surfaces than on acryllacquer-systems. As release agent you can use our T 03-01. MG 321-S FR beige/black fire behaviour according to UL 94, 3 mm thickness V0
