       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.
