New optically clear flexible adhesive for bonding displays 18 December 2019

Techsil Ltd has launched a new optically clear, low viscosity, UV curable adhesive into the UK market. Manufactured by Panacol, Vitralit® 50004 is a one component acrylic adhesive requiring no mixing and has been designed for bonding display screens and laminating optics.

Vitralit® 50004 adheres to a variety of substrates including coated glass, PET and other plastics and films. Its low viscosity means that it can fill cavities fast without trapping air. The adhesive cures quickly with very little shrinkage, meaning there is less residual stress between substrates.

Bonding of large surfaces or lamination of displays is possible by using Hönle’s LED Spot 100 curing system, which matches to the photo-initiators of Vitralit 50004. The alignment of the LEDs of the Spot 100 ensures high intensity and homogenous light distribution. The LED Spot 100 heads can be mounted together without gaps to match the size of the display to bond.

Once cured, Vitralit 50004 is very soft. Thermal stresses between dissimilar substrates are neutralised without causing delamination. Its high degree of flexibility enhances performance through repeated thermal cycles. The cured adhesive is optically clear and non-yellowing, with excellent light transmission.

Techsil has expertise in many diverse adhesive applications including UV curing adhesives. The company offers comprehensive customer support from selecting the right adhesive and on-site testing facilities to transitioning to volume production.
