Warning
Sr nexco is intended for use in dentistry and dental technology.
contact of unpolymerized material (pastes) with the skin or eyes
must be prevented. contact with unpolymerized material may
have a slight irritating effect and may lead to a sensitization
against methacrylates. customary medical gloves do not provide
protection against the sensitizing effect of methacrylates.
Sr connect contains methyl methacrylate (mma). mma is highly
flammable. therefore, keep away from sources of ignition and do
not smoke. mma is an irritant and is irritating to eyes, respiratory
organs and skin. do not inhale vapours.
do not inhale grinding dust. the safety notes on the individual
primary packages and labels have to be observed.
General note
failure to observe the stipulated contraindications and processing
restrictions might lead to clinical failure in certain cases.
Side effects
Systemic side effects are not known to date. In individual cases
allergic reactions may occur. In case of a suspected or confirmed
allergy to one of the components, Sr nexco Paste or respective
other system components must not be used.
Storage instructions
– Store Sr Link in the refrigerator (2–8 °c / 36–46 °f).
– Store Sr nexco Paste layering materials, Sr model Isolation,
Sr connect at 2–28 °c (36–82 °f).
– Syringes should be closed immediately after use (exposure to
light causes premature polymerization).
– Protect the materials from direct sunlight.
– do not use the products after the indicated expiration date.
– Keep material out of children’s reach.
Note on the cleaning of SR Nexco Paste restorations
as the ultrasonic cleaning liquids are highly aggressive, the
composite surface may begin dissolve if the liquid is used
inappropriately. therefore, alkaline cleaning agents with a pH
higher than 8 must not be used.
