NoticeThe colour display is for guidance only. For an exact colour selection, please use our colour sample cards.

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.

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. 5995000400

Application area
  • For window glazing and sealing connection joints in wooden, plastic and aluminium windows.

  • Sealing expansion joints for indoor and outdoor use, such as door, wall, floor, ceiling and window ceiling joints and gutters.

  • Creating a seal between frame and safety glass. When doing so, it should be ensured that there can be no direct contact between the sealant and the laminated safety glass film.

  • Without primer: Wood (varnished, painted — refer to instructions), glass, aluminium (plain, painted, glazed), all types of metal (except lead and copper), enamel, tiles, plastic-coated panels, hard PVC

  • With primer: Concrete, aerated concrete, sand-lime brick, clinker, brick, gypsum, plaster
