Features

• Remains permanently elastic after curing.
• Uses acetoxy curing system.
• Excellent adhesion to non-porous surfaces.
• Does not crack or yellow; resistant to aging.
• Resistant to detergents, cleaning materials, and chemicals.
• Can be applied in all seasons.

• Bathrooms, kitchens, and plumbing applications
• Isolation of electrical sockets and switches

Application

During application, temperature should be between +5 °C and +40 °C. The minimum joint size should be 5×5 mm. For wider joints, the depth should be half the width. A joint filler rod can be used to adjust depth. Silicone should be smoothed using a spatula within 5 minutes of application to ensure contact with the surface. It can be cleaned with silicone cleaner before curing.
