Guide Technical insulation with aluminum adhesive tapes from Coroplast Tape
Applications and properties Only aluminum adhesive tapes complete effective technical insulation
The quality of the adhesive tape determines whether itsucceeds in reliably sealing joints and seams against air and moisture. The adhesive bonds must function for as long as the components to which they are applied – even under difficult conditions.
Aluminum adhesive tapes with the required properties
Self-adhesive pure aluminum tapes from Coroplast Tape are durable and as resistant to cold as they are to heat. They have both a strong adhesive strength and a high shear strength. In addition, our adhesive solutions are appreciated by the building trade because they can be processed excellently at low temperatures.
The first choice for fire protection
With these properties, aluminum adhesive tapes are clearly superior to conventional film adhesive tapes. These products, which are only thinly vaporized with aluminum, achieve neither the fire protection nor the sealing effect of tapes made of light metal. With their A2 (non-flammable) and B1 (flame-retardant) certificates in accordance with DIN 4102, pure aluminum adhesive tapes are therefore always the first choice when it comes to effective insulation of walls and ceilings or insulation in heating, ventilation and air-conditioning systems that permanently prevents energy loss and corrosion damage.
The market standard for technical insulation The optimized Coroplast ALU SE products
Self-adhesive pure aluminum tapes from Coroplast Tape set the market standard in Germany and Europe with their proven quality. This is also true of our market leading product, Coroplast 930 ALU SE. Anyone in the building trade who uses this product knows that this is the highest standard in the market
Proven quality on a new level
This success is no coincidence. We are in constant contact with the industry, so we know exactly what the challenges facing construction professionals are and can recognize new trends to develop our products further in a targeted and practical manner.
This is how the new properties of the optimized Coroplast ALU SE products came about, which can now be ordered from your insulation specialist dealer.
You can look forward to the following strengths:
- improved cold bonding strength
- improved instant bonding strength
- halogen-free
- solvent-free
- optimally matched to all common insulation systems
And you can still rely on the following features:
- fire class B1 "flame retardant" according to DIN 4102
- suitable for shipbuilding (Steuerrad certificate)
- intensively adhering and construction site friendly adhesive
- excellent shear strength even at changing temperatures
- excellent aging resistance
Processing instructions What makes effective interface bonding
-
The final adhesion value is paramount for technical insulation
The decisive factor for the quality of the bond is above all the final adhesion value. It is important to note that you cannot feel this with your finger when you unroll the adhesive tape. This is because the final adhesive strength develops over a longer period of time and can only really be assessed after approximately 24 hours. You can find the adhesive strength values and all other important information for choosing the right product in our product data sheets.
-
Correct application pressure ensures a secured seal
For thermally secure sealing of joints or butt joints, a high degree of crosslinking of the adhesive with the surface is required to be bonded. It is therefore important to press the adhesive tape firmly and evenly during application. Only in this way can the final adhesive force be fully developed. The best way to do this is to use the Coroplast spatula supplied. Keep in mind, although our aluminum adhesive tapes can be processed in damp and cold conditions, the surfaces should be free of dust and dirt for reliable bonding.
-
Avoiding tension during bonding
Aluminum adhesive tapes are designed to permanently seal and insulate interfaces. They are less suitable for processing under mechanical stress. For this reason, bonding should not be carried out under tension if possible. If tension cannot be completely avoided, it is advisable to secure the adhesive tape with binding wire during the cross-linking period.

Adhesive properties The importance of tack and final adhesive strength
Initial tack is not what makes a good adhesive tape for technical insulation. Although initial tack proves to be practical during processing, it is not decisive for the lasting durability of the bond. What matters here is the so-called final adhesive strength, for which the adhesive made of acrylate or synthetic rubber must first crosslink after application.
What lies behind the crosslinking process
Crosslinking is the term used to describe the chemical reaction in which the macromolecular chains of the adhesive bond to one another, thus forming a stable and at the same time elastic network. This process ensures that Coroplast aluminum adhesive tapes develop their full adhesive strength after approximately 24 hours, while offering exceptional shear strength.
The final adhesive force is paramount for aluminum adhesive tapes, when compared to initial adhesive force. Honey sticks well at first. However, this tackiness does not make it a suitable product for technical insulation.
Coroplast spatula Press-on made easy – and now also for textured surfaces
The Coroplast spatula is an important tool. It helps you to seal your insulation system permanently – and much more effectively than with your bare hands. The spatula has two sides – the smooth side allows the aluminum adhesive tape to be applied over the entire surface evenly. The new serrated side allows the adhesive tape to be applied evenly on rough or structured surfaces. Neither the tape nor the surface is damaged in the process. The adhesive tape adheres everywhere and can thus develop its full final adhesive force.
We supply the Coroplast spatula free of charge with every order.
Technical insulation A brief overview of the Coroplast Tape product range
Coroplast Tape has a comprehensive range of adhesive tapes for insulation and interface bonding. In addition to pure aluminum adhesive tapes for all common insulation work on construction sites, we also offer, for example, particularly cold- and heat-resistant products, adhesive tapes with a special sealing effect, high UV resistance or the fire classifications B1 and A2.
ALU SE Series – Market Standard for Technical Insulation
