Country: · Model: UV10 / UV15 / UV10TKLO-2 / UV24TKLO / UV25 / UV26

The one-component UV adhesives and coatings UV10, UV15, UV10TKLO-2, UV24TKLO, UV25 and UV26 cure in 10–30 seconds under ultraviolet light of 320–365 nm, and the most heat-resistant of them work up to +260 °C. They remain liquid until irradiated and contain no solvents, so they are suitable for precise positioning of parts in optics and electronics.

Description

UV10 is a low-viscosity (250–500 mPa·s) acrylate adhesive with a refractive index of 1.557, which cures in 20–30 s and works from −51 to +121 °C. UV15, an epoxy cationic system, cures in a layer from a few micrometres to 0.4–0.5 mm in 15–30 s, its Tg is 90–95 °C after UV and 125–130 °C after a 30 min post-cure at 125 °C, the range reaches +177 °C, and it is halogen-free per IEC 61249-2-21. UV10TKLO-2 is high-viscosity, works up to +204 °C and complies with ASTM E595. UV24TKLO is epoxy-acrylate with a Tg of 120–130 °C. UV25 and UV26 withstand +260 °C, their Tg is 180–185 and 160–170 °C, the refractive index is 1.55, and UV25 cures at as little as 20–40 mW/cm². The series UV15-7, UV15X, UV18S, UV19 and UV22 extend the range, and the tinted UV10TK40RCL and UV15RCL become clear after curing and show that irradiation is complete.

How to choose

The choice is dictated by temperature and optics. For an acrylate adhesive with high clarity use UV10, for an epoxy cationic system with lower shrinkage and no oxygen inhibition UV15, up to +204 °C UV10TKLO-2 and UV24TKLO are suitable, and up to +260 °C UV25 or UV26. If part of the joint stays in shadow, a dual-cure system is needed, for example UV15DC80 or LED401.
