Dark gray highly elastic base.
Premium tape VHB +, increased softness and elasticity.
Purpose - for joining complex, textured (rough), containing plasticizers (flexible PVC ) surfaces, possibly without preliminary preparation (abrasive and/or primer).
Recommendations for the use of VHB adhesive tapes
1. Temperature
Optimum temperature for application of adhesive tapes VHB ranges from+20°C to+40°C. It is not recommended to work with the tape at temperatures below +10°C. An exception is the special tape 4951, which can be applied at temperatures down to 0°C.
2. Abrasion.
The adhesion of the tape to metal can be improved by pre-abrading the surface with a fine-grained sandpaper followed by cleaning the surface with a solvent. Abrasive blasting is required when
there is corrosion on the metal surface.
3. Surface cleaning.
Both surfaces to be joined must be cleaned with a 50% aqueous solution of isopropyl alcohol 50:50. Remove solvent residues with a dry, clean cloth. It is not recommended to use hydrocarbon solvents for cleaning the surface.
4. Dependence of the adhesive bond strength on time.
At room temperature, the adhesive bond strength 20 minutes after application of the tape is approximately 50% of the limit values, after 24 hours - 90%, after 72 hours - 100%. Increasing the temperature decreases the time to reach maximum adhesion (1 hour at 65°C).
5. Pressure
The strength of the adhesive bond of the adhesive tape to the surface increases as the contact area of the adhesive increases
tape/surface. To speed up the establishment of this contact, it is necessary to firmly press the adhesive tape to the surface. After joining the parts to be glued, it is necessary to ensure a short-term strong pressure of the parts
to each other. Recommended contact pressure - 100 kPa.
Learn more about the properties of VHB ™ mounting tape
Double-sided tape 3M ™ VHB ™ (VHB - extra high strength) is widely used as an alternative to traditional mechanical mounting methods ( rivets, screws, welds, etc.) due to the unique ability to leave intact and even surface of the materials to be joined, and the connection line is invisible, providing an attractive appearance of the products. 3M ™ VHB ™ Double Sided Adhesive Tape is the result of more than 50 years of 3M leadership in adhesive tape and adhesives technology.
Advantages of 3M ™ VHB ™ mounting tape
High strength.
3M ™ VHB ™ Double Sided Tape is based on flexible, closed cell acrylic polymers. Double-sided tape (assembly tape) on such a basis, in combination with special acrylic adhesives, has incomparably higher strength than traditional adhesive tapes - for example, foam tape.
Instant installation of products, cheaper assembly, saving time and labor costs.
Double-sided tape 3M ™ VHB ™ assembly tape provides a simple, fast and strong connection of parts, speeds up assembly operations, without requiring special training or production re-equipment. No drilling, welding, screws or glue required. The use of VHB ™ double-sided tape eliminates the need for finishing and cleaning of surfaces.
Saving materials.
3M ™ VHB ™ Double Sided Tape allows you to significantly save materials, both by reducing waste and by using more economical materials. Such a connection makes it possible to distribute the load over the entire area of the connection, and, therefore, to use thinner, lighter, flexible and less expensive materials.
New design possibilities and freedom of design.
C 3M ™ double-sided tape can be used to create structures that would not have been possible with other installation methods. Double-sided tape 3M ™ VHB ™ does not damage the surface of the materials to be joined and is practically invisible between the parts to be joined.
Resistance to external influences.
Double-sided tape 3M ™ VHB ™ is significantly more resistant to external factors media: UV radiation, moisture, salts, solvents, temperature compared to tapes based on foamed polymers. This is due to the closed-cell structure of the base of double-sided tape (assembly tape) and the chemical inertness of the acrylic polymers of which it is composed. Experiments in an accelerated aging apparatus have shown that the strength of the adhesive bond of double-sided tape practically does not change after 7000 hours of cyclic exposure to heat, humidity and radiation.
Viscosity and elasticity, resistance to shock and vibration loads.
