There are several types of silicone sealants available in the market. The primary difference between these types is the curing system they use. The three most common types are:
Acetoxy Cure Silicone Sealants: These types of sealants are cured using acetic acid. They are widely used in the construction industry for sealing and bonding various substrates such as glass, metal, and ceramics. Acetoxy cure silicone sealants are known for their fast curing and excellent adhesion properties.
Alkoxy Cure Silicone Sealants: These types of sealants use alkoxy as a curing agent. They are widely used in the automotive and electronic industries due to their excellent resistance to high temperatures and UV radiation.
Neutral Cure Silicone Sealants: These types of sealants are cured using oxime or alkoxy. They are widely used in the construction industry due to their excellent adhesion properties and compatibility with a wide range of substrates such as plastics, metals, and glass.
Properties of Silicone Sealants
Silicone sealants exhibit several properties that make them ideal for a wide range of applications. Some of these properties are:
Excellent Flexibility: Silicone sealants are highly flexible and can withstand a high degree of movement without cracking or losing adhesion.
Temperature Resistance: Silicone sealants can withstand extreme temperatures ranging from -60°C to 200°C, making them ideal for use in high-temperature applications.
Chemical Resistance: Silicone sealants are highly resistant to chemicals such as acids, alkalis, and solvents.
UV Resistance: Silicone sealants are highly resistant to UV radiation and do not degrade or lose their properties when exposed to sunlight.
