Adhesives and sealants – concepts
  • Adhesion
    Adhesion describes the effect of attractive forces on the boundary surface between the adhesive and the adherend.

  • Activators
    Activators are materials that accelerate or allow the complete hardening of reactive adhesives.

  • Active materials
    Active materials are materials that work as a catalyst during the hardening of anaerobic adhesives, e.g. non-ferrous metals, several steels, several aluminum alloys.

  • Application
    Application is the distribution of an adhesive on the bonding surfaces. The application can take place on one (single-sided application) or both (double-sided application) bonding surfaces.

  • Adherends
    Solid objects that are to be or are adhered to one another.

  • Adhesive film
    The hardened or unhardened adhesive between the adherends.

  • Adhesive
    The adhesive is a non-metallic material connecting adherends to one another using adhesion and cohesion.

  • Bond strength
    The force that has to be effected in order to separate a bonding under tensile, pressure, peel or shear load (basic types of loads).

  • Bonding surface
    The surface of an adherend to be moistened with an adhesive.

  • Cohesion
    Cohesion is the forces between the molecules of a body which hold together the mass particles.

  • Compression strength
    Compression strength is the capacity of a material or structure to withstand axially directed pushing forces.

  • Compression shear strength
    Compression shear strength is one of the basic types of loads.

  • Hardening requirements
    Hardening requirements are characteristics that affect the hardening of reactive adhesives, e.g. temperature, air humidity etc.

  • Hardening
    Hardening is the process in which liquid adhesives transform into solid materials. The adhesive thereby hardens with both the adherends (adhesion) and itself (cohesion).

  • Hardening time
    Hardening time describes the time span between the bringing together of the parts to be adhered and the complete hardening of the adhesive.

  • Single component adhesives
    Adhesives that include all the components required for adhesion in their commercial form.

  • Lubricating
    Lubricating describes the removal of grease and oil films from the surfaces of the adherends using cleaners/solvents.

  • Positioning
    Retention of the adherends in the desired position with or without pressure during the hardening process.

  • Joining
    Joining has two meanings: firstly, the connecting of solid parts and, secondly, the process of bringing together parts that are to be adhered.

  • Joining process
    The joining process describes the assembly of adherends (already moistened with an adhesive) which creates adhesive film(s).

  • Basic types of loads
    Tensile load, tensile shear load, peel load and pressure load. In practice, numerous loads often occur at once.

  • Closed waiting time
    Time between thejoining the workpieces to achievement of hardening requirements.

  • Hardeners
    Hardeners are materials that effect the hardening of an adhesive with a chemical reaction.

  • Fixture time
    An adhesive bond is hand-tight if a force of 0.1 N per mm2 bonding surface has to take effect as shear stress (basic types of loads) to break the connection. Time data underlying the term H. is regarding the time span that elapses from the joining process until the adhesive bond is hand-tight.

  • Catalyst
    A material that causes or accelerates a chemical reaction by its presence without becoming chemically altered itself.

  • Storage life – Shelf Life???
    Storage life is the time span between the creation of the adhesive and the point until which the adhesive’s useable life expires.

  • Solvent
    An organic liquid that dissolves raw materials and the soluble adhesive components without a chemical change.

  • Multi component adhesives 
    In multi component adhesives the reactive components are kept separate and have to be mixed before application for the adhesive to harden. After the components are mixed the adhesive can be used for a certain period of time (pot life). In a new generation of two component adhesives both of the components (adhesive and hardener) are not mixed but are always separately applied to the surfaces to be adhered. The (minimal) mixture of components created in the joining process then effects the polymerisation of the adhesive.

  • Open waiting time
    The time span between the application of the adhesive or activator and the joining of the components to be connected.

  • Passive materials
    Materials that do not support the hardening process of anaerobic hardening adhesives, e.g. stainless steel, various aluminium alloys, precious metals, non-metals.

  • Reactive adhesive
    Adhesives which are based on a chemical reaction for hardening are called reactive adhesives. The reaction creates large-molecular, cross-linked plastics of great strength. Single component adhesives and multi component adhesives differentiated separate category of adhesives.

  • Peel forces
    Peel forces are some of the basic types of loads.

  • Shear forces
    Shear forces are some of the basic types of loads.

  • Pot life
    The time span in which an adhesive preparation is useable for application after the mixing of all components. Once the pot life is exceeded a sufficient moistening of the joining surfaces is not possible with the adhesive.

  • Tensile strength
    Tensile strength is one of the basic types of loads.

  • Tensile shear strength
    Tensile shear strength is one of the basic types of loads.

  • Viscosity
    Viscosity is the resistance to flow of fluids or paste materials due to the their inner friction. Low viscosity liquids are thin, high viscosity fluids are thick.

They can be fitted "blind" (from one side only) with no re-machining/processing and without damage to pre-treated surfaces. Our extensive program offers a wide range of materials, head or shank types as well as standard, medium, long and extra-long grip lengths. New product: KD-blind rivet nut, KD stands for controlled deformation.

  • High tear-out strength as the result of pronounced rivet beading
  • Use on surface-treated parts possible
  • Wide range of head shapes and materials supplied
  • Efficient processing with manual or hydro pneumatic tools

 
 
Blind rivet technology
Blind rivets open or closed end are capable of being installed from one side of the workpiece, without needing access to the back of the item. Many different versions enable a large number of material combinations, no matter if plastic or steel, different material strenghts, grip thicknesses or surface treatments. It is possible to set the rivets either manually or automatically, we offer the whole range - from the simple hand riveting tool up to the automatic auto-feed setting system.

Insertion is complete upon the disappearance of the ball-peak point under the body surface. A specially designed collar on body  inlet retains and protects the ball. When used with hard installation materials the borehole must have a surface roughness of RZ = 10 – 30 µm).
