Panacol introduces an acrylate adhesive solution for bonding displays. Vitralit UD 8540 is very soft after curing, which provides the ability to intercept thermal stresses between dissimilar substrates. It is a one-component, UV-curing acrylic adhesive. It features a dual curing component which reacts to atmospheric moisture. Thus shadow zones within the display frame can also be cured reliably.
The adhesive solution exhibits excellent adhesion to glass and PMMA, which makes it the perfect solution to bond glass/glass or glass/PMMA displays. For bonding glass/PC a specially formulated version of this adhesive is available. Both adhesive variations are free of solvents and silicones.
Large-surface bonding or lamination of displays can be optimized by using Hoenle’s high-performance and energy efficient LED Spot 100 curing system. It matches to the photoinitiators of Vitralit UD 8540. The alignment of its LEDs ensures high intensity and homogenous light distribution, which is of utmost importance for display bonding. The heads can be mounted together without gaps to match the size of the display being bonded.
After curing, the acrylate adhesive solution is very soft with a hardness in the Shore 00 range. Thermal stresses between dissimilar substrates can be neutralized without causing delamination. The cured adhesive is transparent and non-yellowing.
