Facade adhesive solutions, high-quality & cost-effective glass

There are two adhesive bonding solutions for glass facade installation: construction adhesive and structural tape.

Structural tape: Designed for strong and immediate bonding, structural tape is a cost-effective alternative to traditional connection methods in glass facade installation. It is primarily used to bond windows and architectural panels to metal frames. Structural tape is extremely durable, provides long-lasting adhesion, and is easy to install.

Construction adhesive: The facade system includes structural elements providing wind resistance and other horizontal and vertical forces, and facade elements providing weather resistance and thermal, acoustic, and fire resistance properties. These are essential requirements for glass facade adhesive.

Faster and easier facade installation

Structural tape for building facades is a specialized double-sided acrylic tape designed to adhere and bond to both surfaces. Instead of mixing and pumping silicone sealant or using mechanical methods, the installation team only needs to apply the tape directly to the surface and complete the assembly.

The use of structural tape speeds up the assembly process by establishing instant bonds without the need for curing time or waiting for drying. Once the tape is applied, surfaces can be handled immediately, thus reducing issues associated with silicone sealant such as blockages or lumping.

Glass facade adhesive is capable of adhering to various substrates (some requirements may include adherence to concrete), UV resistance, water resistance, moisture resistance, and good resistance to weathering factors. The bond must have permanent elasticity and elongation. Lastly, quick curing without solvents is essential, facilitating an easy and rapid installation process.

Cost-saving in facade construction

As mentioned, the simpler installation process requires less labor time. However, the advantages of choosing structural tape and construction adhesive for building facade applications extend beyond this. Another significant benefit is cost-saving:

Structural tape for building facades: It offers a more reasonable cost in terms of capital expenditure. Compared to other methods such as silicone adhesive and mechanical screws, installation teams would need additional specialized equipment. Sealant requires expensive pumping machines, along with purchasing, maintenance, and repair costs. Structural tape does not require any expensive support tools, thus maintenance costs are virtually negligible. Considering the total cost, structural tape is much more affordable compared to mechanical screws and similar methods.

Construction adhesive for building facades: Traditional sealants and silicones struggle to meet the increasingly complex requirements of modern projects with intricate glass structures while balancing quality and cost. Hitta introduces a new bonding technology (sealant & silicone) from the leading French brand Bostik. The advantage of this adhesive line is extremely fast installation, delivering results that meet European construction industry standards in bonding capability, weather resistance, and fire resistance

A better method

Technical tape for building facades

The bonding of technical tape has been proven to be extremely durable. Additionally, structural tape is UV-resistant, operates within a wide temperature range, and withstands environmental conditions for extended periods. Both tensile and shear strength of structural tape are remarkably high, withstanding heat well (up to 150°C short-term and 100°C long-term).

Adhesion strength testing

The test is as described in the figure:

• The peel angle is 180 degrees.
• The industrial strength tape is pulled for over 2 hours at room temperature.
• Result: good adhesion, minimal displacement, passing the test.

Gravity load testing

The test is as described in the figure:

• Enduring load for 7 days at different temperatures. 
• Load 1: 1500g at 23°C. 
• Load 2: 500g at 93°C. 
• Result: good adhesion, passing the test.

 

Tensile strength test in both directions

The test is as described in the figure:

• Enduring tension from both sides (top and bottom) at room temperature for over 2 hours.
• Result: good adhesion, minimal displacement, passing the test

 

Temperature increasing durability test

The test is as described in the figure:

• Enduring a load of 500g at room temperature for one hour & gradually increasing the temperature. 
• Every 5 minutes, the temperature increases by 3°C. 
• Result: good adhesion, minimal displacement, passing the test.

When installed and applied correctly, structural tape offers several advantages over traditional methods. Structural tape can be used to quickly fix glass and other structural materials directly onto frames. Unlike liquid adhesives, silicone, or mechanical screws, structural tape does not require any complex supporting equipment.

Here are the 8 main advantages of structural tape for building facades:

• Superior adhesion and durability: Traditional methods like nails and bolts are prone to breakage after prolonged wear and tear. These less durable solutions can exacerbate and incur maintenance costs. In contrast, structural tape provides long-lasting adhesion without the need for maintenance.
• Quick installation: Installing structural tape is very simple, similar to applying regular tape, requiring no specialized skills, experience, or tools.
• Labor cost reduction: With minimal training required, anyone can use structural tape. Reducing labor hours and training translates into measurable cost savings.
• Vibration reduction: Structural tape offers vibration reduction capabilities, thereby significantly minimizing noise and vibration between components. By reducing dynamic vibrations, it ultimately contributes to prolonging the lifespan of parts and components.
• Impact resistance: The foam in structural tape easily compresses to help minimize damage between substrates upon impact.
• Flexibility: Structural tape can be used on flat or curved surfaces and can be cut into any size, shape, or design.
• High aesthetic appeal: The virtually invisible bond creates a clean, seamless appearance without any protrusions or excess, enhancing aesthetics.
• Corrosion resistance: Structural tape securely bonds two different materials. The non-conductive bonding layer helps prevent electrical corrosion caused by connecting different types of metals.
