Neutral

• Low modulus of elasticity
• High ageing resistance to UV radiation and weathering
• Indoor and outdoor use
• High tightness
• Meko Free formulation

Silicone Neutral has an insuperable resistance to aging, so much so that even in joints that are 20 years old there are no traces of surface hairline cracks and flaking, in spite of prolonged exposure to ultraviolet rays and atmospheric agents. It adheres perfectly to a great variety of substrates, especially non-porous, but also to concrete and wood, and guarantees permanent elasticity and a perfect seal even without primer. Thanks to its neutral cross-linking skin-over, it does not emit unpleasant odours during application, and  releases no acid or base substances that might corrode metal substrates, and does not attack paints. Silicone Neutral is classified as a non-structural sealant for glazing (type G) in compliance with EN 15651-2.

Silicone Neutral is successfully used in seals subject to differentiated movements between the glazing and the facade as it elastically connects the window or door to the wall and absorbs, without detaching, the movement of the confining construction members caused by thermo-hygrometric dilations or atmospheric stresses both vibrational and mechanical. It thus guarantees a long-lasting perfect seal against water and air, and reduces heat loss. Neutral is compliant with UNI 11673-1, “Fitting doors and windows Part 1: project verification requirements and criteria”, and is therefore the ideal silicone-based sealant not only for aluminium but also for wood or PVC windows.
