Polyurethane Potting Compounds
What are polyurethane potting compounds?
Casting resin is polyurethane based, pourable two-component system. It consists of a filled resin (component A) and an MDI hardener (component B).The system is particularly suitable for the encapsulation of electrical and electronic parts and sensors.
Product Features of polyurethane potting compounds
- High HDT l
- High thermal endurance l
- Low water absorption and good hydrolysis resistance l
- Low mixture viscosity
- Short processing time l
- The use of non-abrasive fillers allows for use of standard two component mixing and dispensing machines. l
- RoHS – compliant
