Media
resistance

Resin systems are often used in very aggressive media and therefore have to offer good chemical resistance properties. Such requirements have to be taken into account in advance when selecting a resin system.

Representative products

WEVOPUR 930 M

  • Good chemical resistance for automotive applications
  • Good adhesion
  • Flexible at low temperatures/low Tg  
  • Good thermal shock characteristics at -40 °C to +140 °C


WEVOPUR 3050

  • Good hydrolysis resistance
  • Curing possible under water
  • High dielectric strength
  • Simple mixing ratio (2:1)


WEVOPOX VP 08/30 / WEVODUR 958

  • Methanol/fuel resistant
  • Good adhesion
  • RT curing
  • High strength
Resins require good media resistance properties when protecting parts in aggressive media.

Chemical resistance as a property of a casted material

Example: Wevopur 930 M mit Wevonat 600
Storage: 24h at 22 °C  and 24 h at 120 °C

System dependence

Media resistance is related to the degree of cross-linking of a system. In most cases, the denser a system’s polymer structure of the system, the better its chemical resistance. For applications in aggressive media, such as brake fluids, hydraulic oils or fuels, a system’s media resistance must always be rigorously examined.
