Two-Component Systems: Filling Lines for Adhesives, Sealants & Pasty Compounds

Unlike many other suppliers, Frans Vermee GmbH can guarantee high quality and reliable availability of two-component systems for the packaging and filling industry.

An important factor when using two-component systems is the filling quantity and quality of the packaging. Precise dosing of the two components can result in a tightly or loosely filled product, depending on requirements and product properties. Precise dosing is particularly important when filling takes place in a continuous process in order to ensure uniform filling.

Tube-in-tube or sleeve-in-sleeve filling is a frequently used method for filling pasty compounds in two-component systems. An inner tube is inserted into an outer tube, leaving a space between the two tubes. One of the two components of the mass to be filled is poured into this space. The other component is inserted into the inner tube. During the filling process, the two components are simultaneously pressed out of the tube through the gap and fed into the container. This method is particularly suitable for pasty and viscous products such as toothpaste, creams, ointments, gel products, chocolate and caramel sauces, mayonnaise and mustard, but also epoxy resins or adhesives, where exact dosing and mixing of the components is of great importance.

Our systems also work in particular with so-called adhesive bonding cartridges, whose two chambers each contain an adhesive component, e.g. epoxy resin and hardener. The two components are mixed through a special nozzle and can then be applied to the material to be bonded. The use of glue gun cartridges enables fast and precise dosing of the adhesive components and is particularly widespread in industrial production.

In order to achieve effective and economical filling, Frans Vermee GmbH offers the SMP booster system. This system enables higher dosing accuracy while reducing material consumption at the same time. Thanks to improved control of the dosing and the speed of the flow, smaller quantities can be dosed more accurately. This leads to lower material consumption and therefore lower costs for the user as well as a reduction in environmental pollution.

Mixtures of chemicals and water can present a challenge for packaging in two-component systems, as they often require compliance with special regulations to ensure safe handling and storage. It may be necessary to use special materials or coatings to avoid chemical reaction or contamination of the liquid. Precise dosing of the two components is also very important to achieve uniform filling. Frans Vermee GmbH meets the requirements of such sensitive products by using flat films and tubular bags, which are characterized by particularly high impermeability. Our systems and processes meet the legal requirements and therefore enable you to fill two-component products safely and in accordance with regulations.

Two-component filling is no longer limited to adhesives. Two-component systems also offer significant advantages in food production—Vermee systems are designed specifically to meet these requirements.

Typical applications:

• Chocolate products: Ganache core (inside) with chocolate shell (outside)—filled in a single filling step
• Sauces & dressings: Oil base and seasoning components are mixed only upon opening—longer shelf life, fresher aroma
• Dairy products: e.g., two-layer yogurts or desserts with fruit and cream layers
• Confectionery & baked goods: cream fillings combined with fruit layers or caramel

All Vermee systems used for food applications comply with the applicable requirements for food contact materials.

In the co-extrusion process, both components are fed through a co-extrusion die simultaneously. The result is a continuous product strand with a defined core and shell—for example, a jam core encased in a quark shell.

The 2K extrusion process offers a fully integrated solution: Since both components are fed through the co-extrusion die in a single step, a separate filling process is completely eliminated—this simplifies the system and reduces maintenance requirements. Throughout the entire length of the product strand, the process ensures uniform distribution of the core and shell. The result is a consistent product appearance that meets the highest quality standards—for every single piece. With production speeds of up to 50 parts per minute, 2K extrusion enables cost-effective operation even at high throughput. Even with varying viscosities of the components used, the core-sheath ratio remains stable and reproducible—a decisive advantage for consistent formulations and reliable product specifications.

Two-component adhesives place special demands on dispensing technology: Both components react upon contact—the pot life is limited. Premature mixing before dispensing results in material loss and, in the worst case, machine downtime.
Vermee systems are designed to keep the resin and hardener completely separate until dispensing and to combine them only in the nozzle or cartridge.

Typical adhesive systems:

• 2-component epoxy resin (EP) – e.g., for adhesive anchor cartridges in the construction industry (CHEMOFAST system)
• 2-component polyurethane (PUR) – flexible sealants and adhesives for industry and trade
• 2-component methacrylate (MMA) – high-performance adhesives for metal and plastic joints
