Rigid Curing Systems
Hard, 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.
The chart below illustrates Shore D hardness and compressive strength values that can be achieved for select systems:
| System Type | Product | Shore D Hardness, 75°F | Compressive Strength, 75°F |
|---|---|---|---|
| Two part epoxy | EP30TC | 85-95 | 24,000-26,000 psi |
| Two part epoxy | EP30NS | 80-90 | 18,000-20,000 psi |
| Two part epoxy | EP21TCHT-1 | 85-95 | 22,000-24,000 psi |
| Two part epoxy | EP21SC-1 | 90-95 | 24,000-26,000 psi |
