- Room-Temperature Adhesive Cure
Product Description
LOCTITE® EA 0151 is a clear, two-component epoxy adhesive that provides optical clarity when used in small quantities. The thixotropic paste combines a 60-minute pot life at 77°F with room-temperature or heat-curing options, allowing time for mixing, dispensing and assembly. It bonds a range of materials, including glass, metals, circuit boards, fiber optics and many plastics. The mixed adhesive is clear and can be supplied through cartridges or prepared in bulk using the documented component ratio. Its 100% solids formulation and electrical properties make it relevant for bonding applications where appearance, controlled processing and dielectric performance are important.
Key features
- Clear mixed appearance: Provides optical clarity when used in small quantities.
- Flexible cure options: Reaches complete cure at room temperature or through documented accelerated heat-cure schedules.
- 60-minute pot life: Provides a typical one-hour processing window at 77°F for a 100-gram mixed quantity.
Applications / Suitable for
- Glass bonding
- Metal bonding
- Circuit board assembly
- Fiber-optic bonding
- Bonding many plastics
