TEROSON EP 5055 is a two-component, solvent-free toughened epoxy adhesive designed for bonding bare steel, zinc-coated steel, and aluminum alloys in automotive and body repair applications. Buyers sourcing TEROSON EP 5055 for structural metal bonding value its combination of high strength and corrosion protection, with a Part A epoxy resin base and Part B amine hardener mixed at a 1:1 ratio by volume for consistent, repeatable results.
Why Body Repair Shops Choose TEROSON EP 5055
Automotive body repair and metal fabrication work often requires an adhesive that bonds dissimilar metal substrates while resisting corrosion over the life of the repair. This product is formulated specifically for bare steel, zinc-coated steel, and aluminum alloys, which is why it is specified in applications where high strength and corrosion resistance are both required at the bond line.
Technical Data (Typical Test Results)
| Part A Base | Epoxy Resin |
| Part A Colour | Black |
| Part A Density | Approx. 1.0 g/ml |
| Part A Viscosity @ 23 °C | Approx. 145 Pa.s |
| Part B Base | Amine |
| Part B Colour | Grey-Green |
| Part B Density | Approx. 1.1 g/ml |
| Part B Viscosity @ 23 °C | Approx. 75 Pa.s |
| Mixing Ratio A:B by Volume | 1:1 |
These properties help fabricators evaluating TEROSON EP 5055 confirm compatibility with their existing dispensing equipment, particularly the 1:1 mix ratio which simplifies cartridge and static mixer selection.
Application and Working Time
- Designed for bare steel, zinc-coated steel, and aluminum alloys used in the automotive industry or body repair shops, where high strength and corrosion protection are required.
- Processed from universal cartridges with manual application tools, such as hand-driven, air-pressure, or battery-powered dispensers equipped with a piston rod.
- Before screwing on the static mixer, press out a small amount of material to confirm both components are dispensing simultaneously.
- Once mixed, the adhesive must be processed within 80 minutes, since viscosity increases as curing progresses; processing time depends on temperature.
- Bonded parts should be fixed in place during cure to prevent displacement before the adhesive has developed sufficient strength.
Because the 80-minute working window is shorter than some general-purpose structural epoxies, shops using TEROSON EP 5055 on larger repair jobs should plan mixing and dispensing sequence in advance to avoid discarding partially cured material.
Sourcing TEROSON EP 5055 Alongside Composite Materials
Metal bonding adhesives like this one are often specified alongside structural resins and composite raw materials in facilities that fabricate hybrid metal-composite assemblies, such as automotive parts or reinforced structural components. Purchasing TEROSON EP 5055 together with resin, gelcoat, and other adhesive products can help buyers consolidate freight and vendor management. As a recommended international brand product available through our supply chain resource support, it can be quoted alongside other composite raw materials for overseas buyers.
For background on test methods commonly referenced for structural adhesive qualification, buyers can consult the ASTM D14 committee on adhesives.
Storage and Handling Notes
Both components should be stored in a cool, dry area away from direct sunlight and kept tightly sealed between uses to protect shelf life. Shops working with universal cartridges should confirm the static mixer size matches their dispensing equipment before ordering in volume, since mismatched mixers can affect mix quality and final bond performance.
Frequently Asked Questions About TEROSON EP 5055
What substrates is TEROSON EP 5055 designed for?
It is designed for bare steel, zinc-coated steel, and aluminum alloys, commonly used in automotive and body repair applications.
What is the mixing ratio?
Part A and Part B are mixed at a 1:1 ratio by volume, dispensed through a static mixer for consistent blending.
How long is the working time after mixing?
The mixed adhesive must be processed within 80 minutes, as viscosity increases once curing begins; actual working time depends on ambient temperature.
What application equipment is required?
It is dispensed from universal cartridges using manual, air-pressure, or battery-powered dispensers equipped with a piston rod.
Can this adhesive be sourced with resin and composite material orders?
Yes, it is commonly quoted alongside resin, gelcoat, and other adhesive products for buyers working on hybrid metal-composite assemblies.
