How to choose the right silicone sealant?

 Silicone sealant is another type of liquid adhesive and is used for many industrial purposes. Unlike other adhesives, it maintains its elasticity and strength at fluctuated temperatures. There are many types of sealant available, and often you might get confused; each silicone sealant is distinct and used for different applications; they have different durability, flexibility and resistance. For a good quality sealant, always choose a reliable Silicone sealant supplier. The silicone sealant is used for various applications like:

• Sealing gaps of bathrooms, showers, kitchens or any other.
• Fixing mirrors to any tiled surface.
• Sealing gutters
• Making soft rubber goods out of them.  

Apart from domestic uses, they are widely used in industrial applications due to many benefits they hold like:

• UV Resistant
• Temperature resistant
• Highest movement capability
• Endured service life
• Longer flexibility

The sealants can be used in glass application and are adaptive to a different temperature, water-resistant and prevent mildew growth. There are majorly four types of silicones used in industries which are:

• High Modulus
• Low modulus
• Neutral cure
• Acetoxy cure

The difference between low cure and high cure is that common cure provides for flexibility. We can stretch it easily after getting a cure, and high cures are more secured, which cater to less flexibility once it is fixed. For example, if you want to seal your bathtub, you’ll use high modulus silicone because it will come in contact with water, and It can stretch and lead to leakage. 

Acetoxy cure produces acetic acid, which makes it smell like vinegar. It has a quick cure but does not have good adhesion. 

Neutral: they release alcohol and also have no smell. They have better adhesive properties and work for more materials like PVC, Plastic, glass, aluminium, lead, stone, polycarbonate, etc. they are relatively expensive and takes more time to cure. Let us have a comparative study upon their qualities so you can have a better understanding:

S.No.	High Modulus	Low Modulus	Acetoxy cure	Neutral care
1.	Hard-wearing	Higher stretchability	Faster cure time	No smell
2.		Durable	More rigid	Excellent adhesive properties
3.		Allow better mobility		Ideal for metal and plastic applications.

 

Applications:

Low Modulus Axetocy: cost-effective, they are used for applications like general buildings and external and internal glazing applications.

High Modulus neutral: used to seal UPVC Widows and doors because of better adhesion and durability.

High modulus axetrocy:  they are generally used for kitchen and sanitary applications.

General-purpose and builders silicone: this silicone is best for building applications and has excellent adhesive properties. They do not contain fungicides and are flexible.

Sanitary silicone: These types of silicones contain fungicides to prevent the growth of moulds. Due to their continuous exposure to moisture, mould build-up is expected; it is essential to select water-resistant silicones.

Glazing silicone: this imparts a very clear finish and robust adhesive property. It is primarily is used for glass applications.

Frame sealants: they are more robust and provide excellent bearing capacity against UV Radiation and weather conditions. It is ideal for sealing windows and doors and is used extensively in buildings and construction.

Neutral Cure Silicone: Neutral core silicon reduces or does not produce acetic acid, making it a better choice. As the acetic acid imparts a pungent smell of vinegar and harms the product, many people prefer neutral cure silicone.

Food-safe silicone, High-temperature silicone and aquarium silicone are other types of silicone used by people for different industrial requirements.
