Neutral silicone Perfect is not suitable for adhesive bonding or filling hollow spaces. Complies with building material class 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. Otherwise there is the risk of streaking. Risk of yellowing on contact with white alkyd resin paints cannot be excluded. The transparent colour is adjusted to be milky/cloudy. When hardening, neutral silicone Perfect gives off an odour typical of silicone. This odour can no longer be smelled once the hardening process is complete. Colour adjustment: matt. Silicone surfaces should not be cleaned with non-abrasive cleaning agents and non-etching cleaners.


Silicone has a tendency to discolour in dark areas where there is no UV exposure. Avoid contact with VKP tape. After skin formation, do not spray any liquid (e.g. sealant smoothing agent or water) onto the joint as spots may form.



If smoothing agent/water is used, it may only be used before the time to form the skin and must be removed completely with a smoothing tool after application. Excess amounts next to the joint must also be removed immediately. Otherwise, there is a risk of staining.



For materials and materials that come into contact with the sealant even after processing, the user must clarify whether their ingredients or evaporation may not cause impairment or change (e.g., discolouration) the sealant joint. To determine the precise colour, use sample card art. no. 5995000400
