High-solid epoxy-based intermediate coat SikaCor EG-1 is a 2-pack intermediate coat based on epoxy resin containing micaceous iron oxide. Low solvent content according to Protective Coatings Directive of German Paint Industry Association
(VdL-RL 04). - Excellent adhesion to hot dip galvanized steel, zinc spraying, stainless steel and aluminium
- High film thickness per coat (up to 120 μm)
- Very good corrosion protection
- Tough elastic and hard but not brittle
- Largely insensitive against shock and impact
|
Usage Designed as a mechanically resistant intermediate coat on steel surfaces exposed to atmospheric conditions, hot-dip galvanized steel, zinc spraying, stainless steel and aluminium.In combination with 2-pack primer and top coats, SikaCor EG-1 is a mechanically water and
