Backfillings for negatives- Processing Instructions
Material- and working- temperature: between 18 - 25 °C. Close containers after use. Seal porous mold surfaces first (ebalta mold sealer). For optimum mold releasing we recommend a special release agent (like T1-1), which can be applied easily with a brush or be sprayed. Releasing of the mold 2-3 times, evaporate for about 20 min. after each releasing. Mixing ratio resin/hardener according to instructions. Stirring rods etc. with residual resin can be easily cleaned with ebalta cleaning agent.
- Brush gel coat, e.g. OH 11
- Gelling of surface
- Brush gel coat together with chopped glass strand
- Cast comp. B into comp. A
- Stir with spiralmixer
- Cast immediately
