Processing Information

 Processing Guidelines

  • Substrates should be properly surface treated and cleaned, as well as free from any contaminants.
  • Mix both components thoroughly for several minutes until a homogeneous mixture is obtained.
  • Mixing with a dual orbital mixer such as a FlackTek or Thinky mixer can improve results. Total mixing time above 2000 rpm should be monitored and done incrementally to avoid excessive heating. Ramped mixing can help achieve homogeneity and allow for proper monitoring of material.
  • The mixed adhesive should be applied to both dry surfaces intended to be mated with a spatula to ensure proper wetting and subsequent bonding.
  • The components to be bonded should be assembled and clamped as soon as the adhesive has been applied. Even contact pressure throughout the joint area during cure will ensure optimum performance.
