After air-drying coatings based on LIOPUR PKS 2845 form transparent films which are tacky at
room temperature.
Because of the film’s flexibility, even at low temperatures and resistance to hydrolysis Liopur
PKS 2845 is especially recommended for making contact adhesives with good peel strength,
used to laminate a wide range of materials.
Joining temperatures should be between 15 and 50°C and adherent surfaces should be
pressed together at > 0,5 bar. Optimum conditions should be ascertained by individual tests.
The good heat resistance can be increased still further by adding suitable water-emulsifiable
polyisocyanates like Desmodur DA
