- Mold Preparation
- Clean the mold from all oils, silicones, waxes and other contaminants eg with Chemlease® Mold Cleaner EZ. The rag used should be changed regularly to ensure contamination is not transferred back to the mold.
- Only use in well-ventilated rooms until the mold surface is "squeaky clean". Normally 4 passes Wipe On / Wipe off are sufficient.
- Spray On / Leave On
- Spray the entire surface of the mold with a thin, even film, distance from the mold should be approx. 10 - 25cm.
- Apply only a thin layer, a damp film appears on vertical surfaces without running, gradients are to be recorded immediately.
- Allow to dry and harden for 15 minutes at room temperature without further wiping. Apply a second coat in the same way. Allow the top coat to harden for at least 1 hour.
- Wipe On / Leave On
- Saturate a clean, lint-free, soft 100% cotton cloth (such as Chemlease® Cotton Cloth) sufficiently. Apply the sealer generously to the dry, clean form and distribute thinly evenly.
- Dry and harden at room temperature without further wiping. Adhere to the curing time of at least 15 minutes (depending on temperature and layer thickness). Depending on the surface condition (porosity of the mold), apply further layers. 1-2 layers are often sufficient. Several layers are required to seal porous material, depending on the structure and material properties (PU or epoxy resin, different densities). Individual preliminary tests are recommended for precise determination.
- Allow the top coat to harden for 30 minutes at room temperature or 15 minutes at 80 degrees Celsius. Only then can the mold be further processed with release agents in the usual way.
- Wipe On / Wipe Off
- Proceed as under "Wipe on / Leave on" but immediately after applying the layer, wipe the still damp layer with another clean cotton cloth. As soon as the product begins to dry, wiping is no longer possible and would produce defects and streaks. Normally 1-2 wipe on/wipe off coats are sufficient. Allow the top coat to harden for at least 1 hour, only then can the mold be processed further in the usual way with release agents.
Storage & Handling
- Storage
Do not store above 38°C. Keep containers closed at all times to avoid evaporation, contamination and premature reaction. If the product is stored in the cold, it must be brought to room temperature before use. Discontinue use if the expiry date has passed.
- Handling
Keep away from sources of ignition during storage and use. Wear solvent-resistant protective gloves when applying.
