Important information
The product is not suitable for structural bonding, e.g. structural facades (structural glazing). Given the variety of paints and other coatings, we recommend compatibility testing to rule out undesirable reactions. Given the wide variety of materials used, it is always necessary to carry out preliminary tests. Does not adhere to plastics such as PTFE, PE and PP
Limitations for use:
It cannot be painted over and is not suitable for underwater sealing. During curing, the sealant emits a small quantity of acetic acid, which may irritate the eyes and mucous membranes. Ventilate the working environment well. In case of accidental contact with the eyes, rinse with plenty of water and seek medical advice
Sizing of the joint:
The size of the joint is extremely important and must be designed on the basis of the dimensions of the object to be sealed so that the sealant can follow the movements without breaking and separating (maximum operating length)
While the technical advice given is based on our experience and should be followed, it is purely indicative and must be confirmed through extensive practical tests. This does not relieve the purchaser of their responsibility to personally test our products to see whether they are suitable for the intended use
Product complies with UNI EN ISO 11600
Declaration of performance (DOP) tested as per EN 15651 — part 1-2-3
For the sealing of expansion joints and connection joints, for joints between wall and floor coverings, staircases, joints of prefabricated panels, joints of partitions, between fixtures and walls. Sealing of glass, glass brick, glazed ceramic tiles, bathroom accessories
All surfaces of the joint should be perfectly clean and dry. The sides of porous joints should be pre-treated with the appropriate undercoat primer for silicone from Würth. Observe the size of the joint. Prevent adhesion on three sides. Extrude the sealant without introducing air during filling of the joint. Smooth out within 5 minutes from application with Würth's special smoothing agent and spatula.
Limitations for use
The product is not suitable for use on surfaces such as marble, granite, quartzite, concrete, fibre-cement and mortar. Acetic acid emitted by silicone during curing may lead to corrosion of untreated metallic surfaces. Not suitable for construction of aquariums
