Automotive manufacturers have many compelling reasons to look for ways to reduce their energy consumption, both in their vehicles and in their manufacturing process. Technological advancements in adhesives mean technical specialists TECHSiL are well placed to provide adhesive solutions which can help reduce energy consumption and revolutionise assembly lines of electronic components.

Energy Efficient, UV Cure Adhesives for Automotive

Using UV-cure adhesives in automotive electronic applications can contribute to energy reduction in several ways. UV-cure adhesives are special adhesives that are cured, or hardened, when exposed to ultraviolet (UV) light. When trying to optimise energy efficiency, they offer several advantages over traditional adhesives.

Faster Curing Time: UV-cure adhesives cure almost instantly when exposed to UV light. This rapid curing time reduces the need for prolonged heating or other energy-intensive curing processes that traditional adhesives might require.

Lower Energy Consumption: Traditional adhesives may need to be cured at elevated temperatures for longer periods of time. This requires energy-intensive heating systems. UV-cure adhesives eliminate the need for these high-temperature curing processes, leading to reduced energy consumption.

Precision Application: UV-cure adhesives are typically applied as liquids and then cured with UV light. This allows for precise and controlled application, minimising waste and reducing the need for rework. The accuracy of application helps ensure that only the necessary amount of adhesive is used, saving both material and energy.

Reduced Thermal Stress: Traditional adhesives can create thermal stress during curing, especially if high temperatures are involved. This stress can potentially damage sensitive electronic components. UV-cure adhesives cure without generating excessive heat, reducing the risk of thermal stress and associated energy losses.

Instant Bonding: UV-cure adhesives provide an instant bond upon curing. This can streamline the manufacturing process, as there's no need to wait for adhesives to set or cure slowly over time. Faster production cycles can lead to energy savings.

Lower Production Footprint: UV-cure adhesives often require simpler and smaller curing equipment compared to traditional curing methods. This can result in a smaller production footprint and reduced energy consumption associated with the operation and maintenance of equipment.

Elimination of Solvents: Some traditional adhesives require solvent-based carriers for application. These solvents can be energy-intensive to produce and can contribute to volatile organic compound (VOC) emissions. UV-cure adhesives are often solvent-free, reducing both energy consumption and environmental impact.

Improved Reliability: UV-cure adhesives often provide stronger and more reliable bonds due to their quick and controlled curing process. This can lead to longer-lasting automotive electronics, reducing the need for repairs or replacements and saving energy in the long run.

Products to Consider - Translucent, Dual Cure UV Adhesives

Launched in 2023 TECHSiL® are excited to introduce a brand new range of one-component, UV curable silicone sealing materials with dual cure feature known as the UV Series Silicones.

All grades in the new range are translucent in colour, with a UV primary cure and a secondary moisture cure at room temperature or with thermal cure. The initial UV cure contributes to a reduction in cycle times. the secondary cure allows for a more complete cure to be achieved in shadowed areas where the UV light penetration is limited - solving a long standing problem which a single UV cure material could not satisfy.

These pioneering new materials can be selectively dispensed on display modules and can easily provide the flowability required to penetrate tight spaces. They have soft post-cure properties that can contribute to providing stress relief of delicate electronic components.


Overall, the use of UV-cure adhesives in automotive electronics manufacturing can lead to more efficient processes, reduced energy consumption, and improved product quality. However, it's important to note that the adoption of UV-cure adhesives might require initial investment in UV curing equipment and process adjustments, but the long-term energy savings and other benefits can outweigh these costs.
