DESCRIPTION
MAX BOND Medium Viscosity A/B is a two-part epoxy based system specially formulated to provide structural bond strength, excellent water resistance for both marine and fresh water and exceptional toughness and impact resistance.
Its long pot life, high performance mechanical properties, and easy application make MAX BOND Medium Viscosity A/B an ideal resin system for hundreds of application where structural strength is required. . MAX BOND Medium Viscosity A/B is 100 % solids and does not contain Ozone Depleting Chemicals (ODC).
MAX BOND Medium Viscosity A/B will cure even in humid and low temperature conditions. It is generally room temperature cured but can be snap cured at elevated temperatures for a short period of time.
MAX BOND Medium Viscosity A/B demonstrates structural bond strengths to a variety of substrates commonly used in composites industry such as, steel, aluminum and soft metals, fiberglass, concrete and ceramic and most plastics.
MAX BOND Medium Viscosity A/B performs well in wide range of service temperature and resists cracking and delamination due to cyclic vibration, thermal expansion and contraction.
