CA 23Aluminum fixing tapeFor edge and terminal sealing as well asvapour-tight repairs
CHARACTERISTICS� waterproof� flexible� self-adhesive� UV-resistant� bitumen-compatible
SCOPE OF USECA 23 is used as an edge and terminal fixing tape inconjunction with surface sealants based on bitumen(e.g. the BT 21 sealing membrane), as terminal sealantin construction work (e.g. capping or "attika" facing,window joints), in the construction of glass roofs asuniversal sealing and repair tape, as vapour barrier. For indoor and outdoor use.
SUBSTRATE PREPARATIONThe substrates must be solid, dry and free of oil anddust. CA 23 adheres without primer on all smooth,non-absor-bent substrates such as aluminium, zincsheet, polyester, acrylic glass (Plexiglas®), polycarbo-nate (Makrolon®), glass or bitumen-based sealing mem-branes (e.g. BT 21).To improve adhesion on absorbent mineral substrates,e.g. concrete, fibrous cement, plaster, brickwork or gasconcrete, it is recommended to prime the substrate withBT 26 or CN 94. Afterwards allow a flash-off time ofapprox. 60 minutes.
APPLICATIONAfter stripping off the release film, CA 23 is applied tothe surface and carefully pressed down. Even betteradhesion is achieved when using a rubber roller.

PLEASE NOTEUse CA 23 only in dry conditions and at temperaturesof +5 °C to +30 °C (but not in blazing sunshine).At lower temperatures, the adhesive substance tends tobe less viscous and less sticky, at higher temperaturessofter and stickier.Please refer in particular to DIN 18 336, 18 338, 18 195, the DS 325 (AIB), the guidelines for flat roofsand the DUD laying instructions for waterproofing buil-dings.Observe the warnings-, safety- and waste disposaladvice given in the safety data sheet.
