| Shim Epoxies for Composite Bonding Applications |
Master Bond has designed liquid shim
epoxy materials for composite bonding applications. These materials eliminate gaps between composite surfaces and offer high compressive strength properties.
Master Bond liquid shims are custom formulated for optimal service in a wide range of environmental conditions, including withstanding exposure to fuel, water ingress, and high/low temperatures.
Key Features of Liquid Shim Epoxies
Liquid Shim Epoxy’s high compressive strength makes them particularly useful for gap elimination in composite bonding applications. Its other features are:
- Excellent lap shear strength
- Low slump
- Abrasion resistance
- High compressive strength
- Ability to withstand CTE mismatches
- Gap filling capabilities
- Resistance to shock, vibration and impact
- Resistance to micro cracking upon high temperature exposure
- Two component, room temperature curing
- Can be stored at ambient temperatures
Uses of Shim Epoxies
They are commonly used in
aerospace applications, such as composite rib-to-skin assembly and other load bearing structures.
- Toughened, thixotropic paste compounds can be applied vertically and have a long working life.
- Faster setting systems streamline production.
- Select grades cure at ambient temperatures or with moderate heat.
- Custom packaging in dual component cartridges (Semkits®) provides convenient handling and ease of usage, while ensuring consistent mix efficiency.
