Description
Granudan, Sealer BN201
Product information:
Sealer BN201 is an exceptionally strong water-based sealer that can be used on all types of surfaces.
When you use Sealer BN201, you have a highly effective and environmentally friendly Sealer that can solve the tasks and fulfill the HSE requirements that are placed on the modern production company today.
Application:
- Wet a clean, soft, lint- and lint-free “cotton cloth” or “mop“, apply an even layer of Sealer BN201 to the surface of the mold, without rubbing hard.
- Wipe immediately afterwards while the surface is wet with a new clean cloth/mop until the surface is dry. Continue in this manner until the entire mold is processed.
Allow the surface to harden for a minimum of 15 minutes before a new layer of Sealer BN201 is applied and wiped off.
This is repeated 2-3 times for epoxy, polyester and metal molds. For untreated plugs or surfaces with large porosities 6-8 times - After the last layer of Sealer BN201, the surface must harden according to the following guidelines:
a. Heat up and hold for 15 minutes at 100°C
b. Heat up and hold for 60 minutes at 70°C
c. Heat up and hold for 2 hours at 50°C
d. 12 hours room temp. at min. 25°C - The mold surface is now ready to be coated with slipcoat.
If a solvent-based alternative to this product is needed, we recommend our “Granudan Sealer GP” which is a highly globally recognized and effective sealer for the protection of molds and tools. Remember, You can combine the use of solventbased Sealer GP as protective mold barrier during maintenance with the use of a water based release agent on daily basis.
“Granudan Sealer GP” also acts as a quick primer for e.g. our “Zyvax Flex-Z 1.0 – 6.0 products” and thus significantly extends the strength, performance and life of the mold.
Note:
Before application, the mold must be thoroughly cleaned to ensure correct bonding from our sealers to mold surface. We recommend using our cleaner: “Granudan Mold Cleaner“, “Granudan WaterClean” or “Granudan GR-08“.
For abrasive cleaning (removal of resin build-up) use our “Smirdex” abrasives for tough epoxy surfaces, and our polishing pastes from “Farécla” for high gloss finishing.
For worn out mold surfaces or surfaces with large porosity, we recommend using our primer “MPP C2698W” before applying sealer and release agent.
