Steady-Resin S+M

Universal monomer, can be processed with all STEADY-RESIN polymer versions. The clear monomer can be mixed with STEADY-RESIN coloured monomers.

Available in Clear and Pink   500ml Steady-Resin S+M

STEADY-RESIN is a highly transparent cold-cure resin, specifically designed for orthodontics and available in three different polymer versions
–S, M and VARIO– in accordance with the different processing types (see below). All STEADY-RESIN monomers can be combined with all
STEADY-RESIN polymers. STEADY-RESIN is fabricated on the base of methyl methacrylate, contains no cadmium and contains tertiary amines
for polymerisation. When processed properly, STEADY-RESIN is a safe medical product and highly biocompatible. Mica (available in silver, gold,
blue, red, green, rainbow, rainbow green, rainbow violet/REF 8144-8152) can be added to polymer; however overdosing can affect the polymerisation process or the stability.
Indication: STEADY-RESIN is intended solely for dental explications and indicated for expansion plates, retainers, activators, splints with adjusted surfaces etc.
Contraindication: The material is not indicated for production of dentures.
Intolerances: Allergy to methyl methacrylate (CAS 80-62-6) or dibenzoyl peroxide (CAS 94-36-0) or p-tolyldiethanolamine (CAS 3077-12-1). In case of highly
sensitized patients it is recommended to place the appliance in water for several hours to minimize the residual monomer content. Please refer to
the corresponding safety data sheet at www.scheu-dental.com/en/download.
Preparation: It is recommended to put the models in warm water at a temperature of 35°–40° C for about 10 min. in order to avoid bubble formation at the
basal surfaces.
Isolation: Apply one thin layer of orthodontic insulating agent (REF 8364) to the models. We rececommend using IMPRIMO® Model Separator (REF 6551)
for insulating 3D-printed models.
Processing: STEADY-RESIN S used for the so called “salt-and-pepper” technique is characterized by excellent stability. The resin is directly applied to the
model that has been insulated with orthodontic insulating agent. Apply monomer first and then alternately apply polymer and monomer using the
spray bottles (REF 8141) and spray nozzles (REF 8138/8139). The last layer to be applied before the polymerisation process should be polymer.
STEADY-RESIN M for the modelling technique is distinguished by excellent values in terms of flowability and processing range. It is mixed in
RESIMIX® cups prior to applying it to the model that has been pre-treated with orthodontic insulating agent.
STEADY-RESIN VARIO can be used universally for both, the salt-and-pepper and the modelling techniques thanks to the extended processing time.
Working parameters: The indicated values are to be understood as recommendations only and may be affected by room temperature and mixing ratio.
Processing time: 6– 8 minutes
Mixing ratio: STEADY-RESIN S 10 : 4 weight proportion polymer : monomer
STEADY-RESIN M / STEADY-RESIN VARIO 10 : 5 weight proportion polymer : monomer
This mixing ratio corresponds to about 2.7 : 1 volume of polymer : monomer.
Polymerisation: Curing shall always be carried out in a pressure pot filled with clean water; polymerisation shall not be interrupted and the values given below
should be neither higher nor lower. Any change to the parameters can lead to the formation of bubbles, inhomogeneity, increased shrinkage and
higher residual monomer content.
Temperature: approx: 45 – 48 °C / ≈ 113 °F
Pressure: 1.8 – 2.0 bar / ≈ 30 psi
Time: 15 – 20 min.
Finishing: Once polymerisation is completed, STEADY- RESIN can be finished and polished conventionally using carbide cutters. The use of respiratory
protection or local exhaust systems is recommended.
Shelf life/storage: For information on the shelf life/storage of the polymers and monomers see label imprint. Processing after the expiration date should be subject
to prior examination of the product. Once the resin has been filled in the transparent dosing bottles, these must be protected from direct sunlight,
as this may lead to polymerisation reactions and to changes in colour. The resin should always be stored in sealed dry containers at a temperature of max. 25 °C and protected from light.
Hazard warnings: The liquid is easily flammable! The liquid causes irritations of the eye, skin and respiratory tracts. Keep away from sources of ignition and
keep well ventilated, do not allow to enter the sewage system. Prolonged and direct skin contact with uncured material and inhalation of
monomer vapours can lead to irritations. Ensure to follow the instructions on wearing protective clothing as well as the information in
the safety data sheets at www.scheu-dental.com/en/download.
Hints: To be used only for the above indication and by qualified personnel. For single use. Serious incidents in connection with the use of the product
