Which epoxy system should I use?

Selecting the right epoxy system can feel overwhelming. This Epoxy System Selection Guide helps highlight the differences between the systems so you can pick which system will work best for your project.

105 System

  • The most customisable system
  • Hardener selection determines the speed of cure
  • Use the mini pumps to accurately and easily dispense the proper mix ratio
  • Fillers can be used to thicken epoxy to the desired consistency
  • Use for everything from basic, long-lasting repairs to the construction of high-performance composites
  • Bonds to: Woods, fibreglass & other reinforcing materials, metals, and more
  • Type of Bonds/Coatings: Permanent, waterproof, structural
  • Coating or Adhesive: Add fillers to make an adhesive
  • Initial Cure: Hardener dependent. 5-24 hours at 22°C
