Silikonisaumaaineet

Silikonisaumaaineet, commonly known as silicone sealants, are versatile materials used for sealing joints and gaps. They are characterized by their elasticity, durability, and resistance to moisture, UV radiation, and temperature fluctuations, making them suitable for a wide range of applications.

The primary component of silicone sealants is silicone rubber, a synthetic polymer. When applied, silicone sealants undergo a curing process, typically reacting with atmospheric moisture to form a flexible, rubber-like solid. This curing time can vary depending on the product and environmental conditions.

Silicone sealants are widely used in construction, both for interior and exterior applications. In bathrooms and kitchens, they are essential for sealing around sinks, bathtubs, showers, and countertops to prevent water ingress and mold growth. Outdoors, they are used to seal joints in windows, doors, cladding, and roofing to protect buildings from the elements. They are also employed in automotive and marine industries for sealing various components.

There are different types of silicone sealants available, including acetoxy cure, neutral cure, and alkoxy cure, each with slightly different properties and applications. Acetoxy cure sealants release acetic acid during curing, which can be corrosive to some metals and may have a vinegar-like odor. Neutral cure sealants are less corrosive and have a milder odor, making them suitable for a broader range of materials, including sensitive metals and plastics. Alkoxy cure sealants offer excellent adhesion and low odor.

When selecting a silicone sealant, factors such as adhesion to specific substrates, flexibility, color, and resistance to environmental factors should be considered. Proper surface preparation is crucial for achieving optimal adhesion and a long-lasting seal.
