  • For composite-metal bonding
  • Potlife: 15 minutes

Westlake BP20 is a solvent-free epoxy-based bonding paste which was especially developed for fast setting bondings in composites applications and for bondings of composites and metal. This bonding paste is, for example, very suitable for bonding and repairing wind turbine blades. 

BP20, which is also known as Epikote Resin MGS BP20, has a good degree of cure even at lower ambient temperatures. To achieve full mechanical properties and thermal resistance, post-curing of at least 3h 50-60°C is recommended. However, good mechanical properties are already developed after initial curing of 24h RT.


MGS BP20 is available in cartridges of 400 ml (side by side) and 216 ml (u-TAH cartridge) and is therefore ideal for precise and clean bonding. This epoxy adhesive should only be used with the correct mixing tubes that ensure good mixing and low pressure loss.

Benefits of Westlake BP20 bonding paste

  • Fast adhesion to composites and metal.
  • Long processing time (15 minutes).
  • Developed for professional applications, but also suitable for DIY projects.

Instructions for use 

We recommend using this bonding paste in the following way:

  • Remove cap nut and plug. 
  • Squeeze out material until hardener and resin are on same level. 
  • Attach mixer and secure with cap nut. 
  • Reject the first 5-15 grams until colour is homogenous. 

We recommend storing BP20 in the dark (without exposure to direct sunlight or UV) at temperatures between 15-30°C. The material does not tend to crystallize, but lower temperatures make processing more difficult. MGS BP20 can be stored for 24 months in the original packaged and closed cartridges. When processing MGS BP20 at low temperatures, the cartridges should be warmed up to 20-40 °C before use.
