G838 / H925 epoxy gel coat system Price: 37.80 EUR / 1.27 kg set (1.0 kg resin + 0.27 kg hardener) Color: white and black Thermal stability: Tg1 = 90 oC / 194 oF after 24 hours at ambient temperature + 8 hours at 60 oC / 140 oF Mixing ratio: 27 hardener to 100 p.b.w. resin Pot life of 150 g at 20 oC / 68 oF: 17 minutes Curing time: 6 hours Application and curing temp: 18-30 oC / 64.4-86 oF, humidity < 80% The G838 / H925 is a two component epoxy gel coat that is very easy to spread with brush or roller, and hardens practically without shrinking at room temperature. It gives a hard surface with resistance to abrasion and is easy to polish. Its thixotropic but nevertheless supple consistency makes the resin/hardener mixture easy to apply without bubbles with a shorthaired brush in a layer thickness of 1-3 mm. The G838 / H925 system does not run down at edges, corners and vertical surfaces. Allow to gel before applying a second coat. To avoid the risk of delamination, lamination must begin with no delay as soon as the gel coat is no longer tacky. If needed, the system can be made thinner by mixing together with other FIBERMAX epoxy systems or epoxy solvent.
