Master Bond One Part Epoxies

One part epoxy systems require no mixing and simplify processing. These products are available in liquid, paste and solid (such as films/performs) forms. Thermal curing, UV light cure and dual UV/heat curing systems are compounded to meet demanding specifications.

One part epoxy compositions are designed to eliminate waste, accelerate productivity while alleviating concerns regarding mix ratios, weighing, working life and shelf life.

Common Applications of One Component Epoxy Systems

Specially formulated one component epoxy systems feature outstanding performance properties, long-term durability and easy application. These no mix compounds are employed in the electronic, aerospace, medical, electrical, automotive, oil/chemical processing and optical industries.

Curing Mechanisms of One Part Epoxy Systems

In thermal curing epoxies latent curing agents are blended into epoxy resin single component formula so that shelf life stability is maintained before heat activation at specified temperature.

  • Heat cure. Most one part systems require a temperature of 125°C to 150°C for curing. They fall into three categories based on temperature and curing time: conventional, fast and snap curing.
  • Low temperature heat cure (80°- 100°C). Read more about low temperature heat curing epoxies.
  • B-staged epoxy systems have been partially cured and are solid at room temperature. They can be liquefied and fully cured at higher temperatures. Read more about B-stages epoxy systems.

For UV light curing epoxies, the reaction is activated by a suitable light source at the proper intensity and wavelength. This type of systems offers fast cure speeds and lower energy consumption.

Premixed and frozen epoxies are thoroughly blended two component systems that are packaged in single part cartridges or syringes. These systems cure at room temperatures. Read more about premixed and frozen epoxies.
