Two-component technologies meet the bonding, sealing and assembly needs of industry, from construction to aerospace. These technical products, whether epoxy glues, polyurethane adhesives or sealants, require appropriate packaging to maintain their chemical properties right through to their final application.
The success of a project using two-component systems relies on four technical elements: the storage cartridges, the mixers, the filling service and the application equipment.
Two-component cartridges
The use of two-component products requires packaging that combines technical precision and practicality. Etraves is your expert in cartridges designed for theapplication of epoxy adhesives and resins, whether for single-component solutions (high-temperature curing) or two-component (curing at room temperature).
To meet a wide range of industrial needs, available volumes range from 12.5ml to 1125 ml, adapting to every type of application:
- Construction sites prefer epoxy and polyurethane adhesives for their structural assemblies.
- The automotive industry relies on sealants and structural adhesives to guarantee the strength of assemblies.
- The electronics industry uses these systems for the precise encapsulation of sensitive components.
- The aerospace industry relies on these technologies to assemble parts subject to extreme stress.
The cartridge technology incorporates a dosing system that guarantees the correct ratio between components, a decisive parameter in obtaining the expected mechanical and chemical properties.
Static mixers
The static mixers ensure homogeneous mixing of the two components during application. The internal design of static mixers ensures uniform product distribution thanks to a series of baffles that create a spiral flow. This mixing technique adapts to different product viscosities and specific mixing ratios.
A number of features determine the choice of a mixer:
- Nozzle diameter: determines flow rate and application speed
- Number of mixing elements: influences final mix quality
- Product compatibility: avoids undesirable chemical reactions
- Cartridge adaptability: guarantees safe installation
Mixers can be used with different types of products, such as structural adhesives, sealants or resins. The choice of mixer depends on the physical and chemical properties of the components to be mixed, and the requirements of the final application.
Are you looking for a static mixing nozzle to ensure homogeneous, simultaneous mixing of the two components? Etraves offers a wide range of static mixers adapted to the different two-component systems available on the market.
Filling service for bi-components
Visit packaging of two-component products requires technical expertise and specialized equipment. The filling process follows a rigorous protocol, beginning with the transfer of products from 20-liter kegs or 200-liter drums to volumetric dosing machines. This equipment enables precise cartridge filling while preserving the properties of the components. Etraves is a specialist in the packaging of polyurethane, epoxy and silicone adhesives.
Technical stages of filling :
- Product transfer under controlled conditions
- Volumetric dosing adapted to the ratio of each formulation
- Cartridge pistoning for optimum sealing
- Possibility of nitrogenizing the product to improve shelf life
- Customized labelling and final packaging
The flexibility of the service adapts to production needs, from small runs to larger volumes. Each batch is checked for filling conformity, ratio compliance and cartridge tightness.
Two-component spray guns: professional application tools
The choice of two-component spray guns and their accessories determines the quality of product application. These tools are available in manual, electric or pneumatic versions, depending on use requirements and volumes to be applied. Guns can be adapted to different cartridge formats, from 75 ml to 900 ml, for even product application.
A range of equipment to suit every need :
- Manual two-component spray guns: for spot applications and precision work
- Electric models: provide constant flow for extended applications
- Pneumatic versions: for intensive use in industrial environments
Accessories complete the equipment:
- Cartridge holders for vertical storage
- Adapters for different cartridge formats
- Spare nozzles for specific applications
- Pressure regulators for pneumatic models
Gun selection depends on a number of factors: product viscosity, daily application volume and accessibility constraints.
