Protective Films

​​The invention of touch-screen technology has changed how we interact with technology. The use of protective films to protect these electronic devices during and after the manufacturing process is required to avoid damage and scratches that may degrade the optical clarity of the screen.     

Our innovative polyaddition silicone pressure-sensitive adhesives (PSAs) are ideal for making protective films for electronic applications, to shield screens on televisions, mobile phones, watches and tablets/pads. They bond well on low-surface-energy substrates, including very low surface energy, easy-clean, oleophobic coatings used to reduce fingerprint marks.

Working on a range of substrates, silicone PSAs can now provide adjustable peel adhesion options to work with different application requirements. Adhesion ranges from low peel adhesion for television & mobile screen/ITO screen protection during transport, and high peel adhesion for permanent protective films for daily protection of mobile displays.

Key advantages of silicone PSAs for screen protection

SILCOLEASE^™ PSAs offer a range of peel forces for protective film applications. These materials can be applied and cured in seconds to offer the following features:   

• Very good wetting characteristics to enable sticking on low surface energy surfaces
• Steady peel force profiles for a smooth release
• Good aging & UV resistance to avoid changes in peel strength and yellowing
• High temperature resistance (up to 270 °C)
• Easy degassing to avoid bubbles for crystal-clear coatings with zero optical defects
• No residue remaining upon removal of the protection film 
• High optical transparency and clarity to retain the high definition of the screen.
