- Product Uses
Use of Pangel® OM4 as a rheological additive is recommended in the following applications:
- Anticorrosive coatings
- Solvent asphalt coatings
- Bituminous undercoats
- Waterproofing and Pavement repair
- It requires the use of a polar activator at 30 - 60% on clay basis. This will normally be mixed with 5% of water in the mix
- Polar Activator Role
- Pangel® OM4 require the use of a polar activator at 30-60% on clay basis. This will normally be mixed with 5% of water in the mix. They are used for promoting the aggregation of bentonite platelets.
- Polar activators are used when a pregel is made. Pregel normal concentration is between 5-6% clay concentration in solvent.
Recommended polar activator (based on Pangel® OM4 weight)
Metanol/H₂0 (95:5) 33% Ethanol/H₂0 (95:5) 50% Acetone/H₂0 (95:5) 60% Propylene carbonate/H₂0 (95:5) 33% Propylene carbonate 33%
