FERMAGLUE® - the right adhesive for a variety of applications.

 

The two-component polyurethane adhesive systems FERMAGLUE® from Sonderhoff Chemicals are used for gluing components from various user industries. The  components to be joined can consist of different substrates, either thermoplastics or thermoset (also fiber-reinforced) plastics, plastics with metallic components, metal or glass, glass-plastic or glass-metal combinations.

The FERMAGLUE® adhesive systems are available in different degrees of hardness, which can be modified according to customer requirements. Various adhesives can be applied with different viscosities from liquid to stable.

The adhesive application is carried out with the mixing and dosing systems developed by Sonderhoff for this purpose.

The application process

 

The adherence to a precisely defined mixing ratio of the two FERMAGLUE® adhesive components is the prerequisite for a perfect adhesive result.

The chemical reaction of components A and B already starts with the dynamic mixing. The FERMAGLUE® adhesive is applied over the mixing head nozzle very precisely to the contour of the component. During the still open processing time, the components are assembled.

The FERMAGLUE® adhesive systems cure under room temperature and create a firm and durable adhesive bond between the assembled parts. The curing rate is variable over the formulation in wide ranges. The through-hardening can be accelerated by gentle heating in the tempering furnace or by infrared irradiation.

The material processing and dosing of the FERMAGLUE® adhesives takes place with the high process accuracy of the mixing and dosing machines from Sonderhoff. The semi or fully automatic process can be well integrated into existing production concepts.

*The description of the possible fields of use of our products as well as the technical data and values only have a general character and do not mean that a certain product can be used under all conditions in the respective field of use. In this respect, the stated field of use is not a binding specification or usage provision. Due  to the great number of environment variables and their influences (e.g. temperature, test specimens, size, interaction with substrates, influence of machines, or the like) you as our customer must check whether the product is suitable for your specific field of use. We will be pleased to assist and advise you in this respect.

Good reasons to use FERMAGLUE®*

 

  • FERMAGLUE® adhesive systems are used for safe gluing of different component substrates.
  • FERMAGLUE® adhesive systems are applied to the components automatically with the mixing and dosing systems from Sonderhoff or via static mixing.
  • FERMAGLUE® adhesive systems meet the most common adhesive requirements in many industries.
  • FERMAGLUE® adhesive systems have very good resistance to many chemicals.
  • FERMAGLUE® adhesive systems have very good adhesion to thermoplastics or thermosetting plastics (also fiber-reinforced), plastic-metal compounds, metal or glass.
  • FERMAGLUE® adhesive systems are adjustable to different degrees of hardness.
  • FERMAGLUE® adhesive systems (soft to medium hard) are distinguished by their high elasticity and a wide expansion spectrum. They thereby avoid cracks in the bond, which can arise due to different thermal expansion of different component substrates.
  • FERMAGLUE® adhesive systems (medium hard to hard) have a high tensile and shear strength and are used for structural gluing.
  • FERMAGLUE® adhesive systems have high tensile strengths up to 20 MPa.
  • FERMAGLUE® adhesive systems can be used with different viscosities ranging from liquid to stable for glue beads of different sizes.
