\n Black&Light<\/span>\n Technology<\/span>\n <\/h1>[\/vc_column][vc_column width=”1\/2″][vc_column_text css=””]Conventional black adhesives are absorbing a high percentage of light intensity. For this reason, uv curable adhesives are generally transparent. If common black adhesives are cured with uv light, they cure only in very small layers of a few microns. This results in surface \u201cskin\u201d formation, but not a complete cure. Usually, a secondary curing mechanism is then necessary, for example with heat.[\/vc_column_text]\n

During the curing process, the Black & Light technology within the adhesive enables the UV rays to penetrate and complete a full cure.\u00a0 Once the adhesive polymerization is complete, the structure of the Black&Light technology prohibits light transmission. Thus, black adhesives with high optical density can now be cured in a single curing step with uv light only. This process is irreversible.<\/p>\n

[\/vc_column_text][vc_empty_space height=”15px”][vc_column_text css=””]These new Black&Light adhesives are mainly targeted at applications in optical bonding and optoelectronics where high optical density is needed. They are also suitable for optoelectronic applications to help minimize reflections and enhance sensor transmission values, or the black uv epoxies can be applied as glob top or encapsulation.[\/vc_column_text][\/vc_column][vc_column width=”1\/2″][vc_video link=”https:\/\/www.youtube.com\/watch?v=xPhejiMwG-0″ css=””][\/vc_column][\/vc_row][\/vc_section][vc_section][vc_row][vc_column width=”1\/2″][vc_single_image image=”2657″ img_size=”full” css=””][\/vc_column][vc_column width=”1\/2″][vc_column_text css=””]<\/p>\n

Black&Light Compatible with most Vitralit\u00ae<\/sup> Epoxys<\/h3>\n

[\/vc_column_text][vc_empty_space height=”15px”][vc_column_text css=””]The Black&Light technology is compatible with most epoxy-based Vitralit\u00ae<\/sup> adhesives from Hoenle. The technology has no influence on the halogen content. The Black&Light adhesive systems can be very specifically adapted to specifications of the respective application for amount of light blocking and depth of cure.<\/p>\n

[\/vc_column_text][vc_empty_space height=”15px”][vc_column_text css=””]Another major advantage of the Black&Light adhesives is storage: As the the Black & Light epoxy adhesives do not cure at room temperature or elevated temperatures, they can be stored and shipped at room temperature or under normal refrigeration and need not to be stored deep-frozen.<\/p>\n
