S 69 The acetate silicone for clean rooms and room ventilation systems
OTTOSEAL®
S 69
Technical Datasheet
Characteristics: - 1-component acetate-curing silicone sealant
- Good chemical resistance (e. g. to cleaning agents and disinfectants)
- Excellent weathering, ageing and UV-resistance
- High resistance to notches, tension and tearing
Fields of application: - Hospitals, food processing factories
- Elastic joints in cleanrooms and other medical rooms with strict requirements to hygiene and frequent
use of cleaning agents and disinfectants, e. g. operating theatres, medical examination rooms,
medical laboratories
- Sealing of ventilation systems made of non-corrosive materials
Standards and tests: - Tested for applications in the cleanroom sector by the Institute for Hygiene Gelsenkirchen, Germany
- Tested for compatibility when in contact with food (by the Chemical Laboratory Dr. Stegemann,
Georgsmarienhütte, Germany)
- Suitable for use in room ventilation systems according to VDI 6022 (Ass. Of Germ. Engineers), sheet
1 tested according to DIN EN ISO 846 (by the Institute for Hygiene Berlin, Germany)
- Suitable for applications according to IVD instruction sheet no. 21+31+35 (IVD = German industry
association sealants)

Important information: Before applying this product the user has to ensure that the materials in the area of contact (solid, liquid
and gaseous) are compatible with it and also amongst each other and do not damage or alter (e. g.
discolour) each other. As for the materials that will be used at a later stage in the surrounding area of the
product the user has to clarify beforehand that the substances of content or evaporations do not lead to
an impairment or alteration (e. g. discolouration) of the product. In case of doubt the user should consult
the respective manufacturer of the material.
While curing small amounts of acetic acid are released.
Ensure good ventilation during application and curing.
The required vulcanization time prolongs with increasing thickness of the silicone layer. One-component
silicones must not be used for full-surface bonding applications unless special constructional
prerequisites are met. If one-component silicones are to be used for thickness layers of more than 15
mm please contact our technical department beforehand.
Due to interaction with liquid or gaseous chemicals e.g. iodine, bromine or aldehyde containing
substances, the silicone may discolour. It is adviseable to carry out tests before usage!
Avoid contact with materials which contain bitumen and which release solvents, e. g. butyl, EPDM,
neoprene, insulating- and bituminous paint.
Please contact our technical service department before processing joints with high chemical or physical
stress.
Remark on the processing of the colour "stainless steel": Please note that when "modelling" the silicone,
i. e. when silicone layers are pushed on top of each other (e. g. in corner areas) dark, clearly visible
dividing lines could appear. These dividing lines can not be removed by smoothing the lines afterwards.
This effect occurs solely for the colour "stainless steel" and is caused by a special colour pigment which
is necessary to create the metallic effect. It is a typical characteristic of the colour "stainless steel" and it
does not represent a deficiency of the material. In order to avoid such effect, layers of silicone should
not be pushed on top of each other when smoothing material.
