Neutral silicone Special is not suitable for adhesive bonding or filling cavities. Complies with building material class B2 in accordance with DIN 4102. Due to the large number of existing paint and glazing formulas, especially on alkyd resin paints, oil-based coatings and powder-coated aluminium, it is necessary to perform your own tests. Remove excess smoothing agent on the glass and frame. Risk of yellowing on contact with white alkyd resin paints cannot be excluded. The transparent colour is adjusted to be milky/cloudy. Colour setting: glossy. Silicone has a tendency to discolour in dark areas where there is no UV exposure. Avoid contact with VKP tape. For materials and substances that come into contact with the sealant after processing, the user must ensure that their content or fumes cannot cause any impairment or alteration (e.g. discolouration) of the sealant joint. To determine the precise colour, use sample card art. no. 5995000401
Neutral silicone Special can be used for sealing between frames and VSG glass. When doing so, make sure that there is no direct contact between the sealant and the VSG film.
1) Different polycarbonate types require adhesion and compatibility tests prior to application. Stress cracks can appear in particular when applying on cutting edge.
No bag tips, art. no. 0891601001, are provided with the 600 ml bags. These must be ordered separately.
*This ten-year warranty applies exclusively to product properties relating to weathering, UV and ageing resistance and colour fastness. Functionality cannot be guaranteed as this is dependent on proper application.
