Ebalta Kunststoff Gmbh MG 321 FRComp. A+B

ebalta MG 321 FR 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 FR beige fire behavior according to UL 94, 3 mm thickness V0 With MG 883 the potlife of MG 321 FR beige can be set up to 120 secs.
