Rigid Curing Polymer Systems for Industrial ApplicationsHard, rigid curing adhesives, sealants and coatings offer high physical strength properties. They are commonly employed in many structural bonding applications. These systems cure at room temperature, upon exposure to heat or exposure to UV light.

Key Benefits of Master Bond's Rigid Curing Compounds

Master Bond's rigid curing compounds are designed to offer outstanding performance in harsh environments. Advantages of this type of system includes:

  • High tensile and tensile shear strength
  • Wear resistance
  • Dimensional stability
  • Exceptional compressive strength
  • High glass transition temperature (Tg)
  • Superior chemical resistant properties

Products exhibit Shore D hardness ranging from 70-90. One and two component epoxy formulations are solvent free and are available for use in low, medium and high viscosities. They have excellent bond strength to a wide variety of substrates including metals, glass, ceramics. Select grades contain specific fillers such as quartz, silicon carbide, alumina, or nickel to boost rigidity. These compounds are also noted for providing enhanced erosion/corrosion protection, resistance to wear/abrasion and low shrinkage upon cure. Heat curing these systems will increase cross linking density which will improve their rigidity and processing speed.

Rigid light curing products cure on demand for precise alignment between substrates requiring exact positioning. They feature good wetting properties and high optical clarity. UV curable hardcoats guard clear plastic substrates such as polycarbonates, polymethylmethacrylates from scratching, common chemicals, staining. They are employed on automotive headlights, touchscreen displays and safety glasses. Nanosilica filled UV curing and dual UV/heat cure products have been developed for advanced performance requirements. It is important to note that dual cure products will cure effectively in "shadowed out" areas with moderate heat exposure. They have successfully passed NASA low outgassing specifications and can cure in thicknesses of a few microns to about 1/8 inch.
