New Choice for Composite Material Bonding: New Launch of VHB™ GPL Series
#BM Tape News or Information ·2025-11-05 16:34:15

With the advancement of science and technology, labor/process costs in many industries have risen sharply, and various traditional connection methods are facing challenges. For example:
-
Mechanical fixation including screws, buckles, riveting: low production efficiency, damage to the substrate surface, and difficulty in sealing.
-
Welding: dangerous construction, rising costs.
-
Glues and sealants: cumbersome construction, high defect rate, low curing efficiency, large space occupation, and pollution to the construction environment.
At the same time, as various materials are widely used in the current market, the demand for composite material bonding continues to increase. For example:
-
Glass: With the continuous reduction of the cost of tempered glass, more device panels and membrane switches have begun to use tempered glass to replace traditional plastic panels, achieving a more beautiful design. However, tempered glass is not easy to process, and has higher fixation requirements.
-
Plastics: Especially PS/PP, due to their low cost and high performance, have been more widely used. However, low surface energy plastic products are difficult to bond, mechanical fixation is not beautiful enough and the mold structure is complex.
-
Composite materials are widely used in the construction and manufacturing industries, including fiberglass and carbon fiber, etc. However, it is difficult to use traditional connection methods such as welding or riveting between composite materials, so high-performance adhesive solutions are needed.
And since its launch in 1980, with continuous process improvement and gradual improvement of the product portfolio, 3M™ VHB™ tape products have become the first choice for many traditional industries to upgrade the process of connection solutions and reduce costs while increasing efficiency.
Why is that? We have to start from the very beginning, the principle of the bonding solution.
(Bonding Principle)
Different from mechanical connection methods, the tape does not damage the substrate surface. The adhesive wets the substrate surface to achieve close contact, thereby continuously establishing the intermolecular force (van der Waals force) between the adhesive and the substrate surface.

(Wetting - Forming Intermolecular Forces)
At the same time, 3M™ VHB™, through its own closed-cell acrylic structure, provides extremely high MPa-level cohesive strength and excellent durability of more than 30 years. In addition, the viscoelasticity of the tape itself can also bring shock absorption and buffering effects, and the closed-cell structure itself enables 3M™ VHB™ to support IPx7 level waterproofing.

(Cohesive Force Within the Tape Body)
It is these unique properties that make 3M™ VHB™ adhesive solution have the following advantages over mechanical fixation and glue bonding:
-
Adhesive bonding does not damage the surface of the bonded substrate, can be removed cleanly, and avoids electrochemical corrosion at the same time.
-
Adhesive bonding itself is a physical process at room temperature, no heating required, no external energy required. The construction is safe, clean and pollution-free, simple and easy to operate, with low demand for labor.
-
3M™ VHB™ adhesive solution can achieve IPx7 level sealing and waterproofing of the bonding surface through a suitable design scheme, and its durability has been verified by 30 years of salt spray test.
-
3M™ VHB™ tapes have a complete product portfolio, meeting customers' bonding needs for different colors and thicknesses, and different substrate surfaces, especially optimized for tempered glass and composite materials that are not easy to be mechanically processed.
-
It simplifies the customer's bonding surface design, making mold design simpler and faster. At the same time, the tape is convenient for small-batch rapid trial production to facilitate design improvement and iteration.
-
The viscoelastic properties of 3M™ VHB™ can help customers with shock absorption and noise reduction, and it is widely used in the bonding of van skin and speaker interior to improve NVH performance.
Since its launch in 1980, 3M™ VHB™ has been widely used in various connection solutions across hundreds of products in several major industries, such as the bonding and fixation of glass curtain walls, the bonding of home appliance panels, the fixation of reinforcing ribs for vehicle skin, the bonding of electronic device screens, etc
And today, we are honored to launch a newly developed product specially for the special needs of the Chinese market: 3M™ VHB™ Tape GPL Series.
(GPL Introduction)

A
Product Features and Positioning
-
A cost-effective general-purpose product, the newly upgraded adhesive is suitable for most common substrates, including metals (high surface energy), ABS/part of sprayed surfaces (medium surface energy), part of TPE/PP materials (low surface energy), as well as various composite materials such as fiberglass/carbon fiber.

(Reference Data)
-
Enhanced initial adhesion, greatly improving customers' on-site work efficiency, quickly and stably reaching the operating strength, more suitable for automated tape application, achieving faster tape application speed.
(GPL Low-Temperature Automation)
-
It can be used efficiently in working environments as low as 0℃, and the same product can be used in all seasons without replacement.
-
At the same time, it ensures the same excellent other properties as other 3M™ VHB™ products, including high outdoor weather resistance (resistance to high and low temperature, UV, moisture and solvent erosion), super strong sealing and waterproofing, excellent shock absorption and noise reduction ability, etc.

GPL Successful Applications
The target market of GPL is the general industry. On the one hand, it is suitable for small and medium-sized manufacturing customers' demand for flexible design solutions and small-batch efficient production. The simple design reduces mold complexity, facilitating rapid small-batch production and design iteration. On the other hand, we provide a complete set of automated tape application solutions. At the same time, GPL's improvement for fast tape application and low-temperature operation performance can also meet the demand of large-volume customers and projects for large-batch rapid automated production.
Since last year, we have widely started testing and trial use of GPL products in various industries, and have received positive feedback, for example:
1. Passed the test of a customer and applied in glass partition walls in the construction industry;
2. Passed the verification of a customer and started to be used in component fixation in the smart home industry;
3. Passed the test of a customer and started to be used in glass panel bonding applications in the home appliance industry;

Outlook
It has been 40 years since the launch of 3M™ VHB™ products.
In these 40 years, the output of 3M™ VHB™ has exceeded 8.4 billion meters, gradually promoted from the place of invention to the whole world, serving customers in all industries around the world, and has been widely used in hundreds of products.

And as mentioned at the beginning, in China, in addition to continuing to maintain a leading position in the home appliance, construction, electronics and other industries, with the continuous development of manufacturing, 3M™ VHB™ tape bonding solution has begun to rapidly replace traditional connection solutions in other segmented manufacturing industries, entering a period of explosive promotion.
And GPL, this product further improved for the needs of Chinese customers, also reflects the innovation concept of 3M, and will definitely further help customers enhance their own product competitiveness through more advanced design solutions, higher production efficiency, and lower comprehensive costs.
