Benefits of Neutral Silicone Sealant

Safety
One of the primary benefits of neutral curing silicone is that it does not release any acidic or corrosive by-products during the curing process. This is important in coldstore construction because acidic by-products can cause damage to metal surfaces and other materials, leading to premature failure of the sealant and potential safety hazards.

Excellent adhesion properties
Another advantage of neutral curing silicone is that it has excellent adhesion properties, even on difficult surfaces such as galvanised steel or polyurethane foam insulation. This makes it an ideal choice for sealing joints and gaps in coldstore construction, where a strong and durable seal is essential for maintaining the integrity of the structure.

Highly resistant to UV radiation
In addition to its superior adhesion properties, neutral curing silicone is also highly resistant to UV radiation and extreme temperatures, making it an ideal choice for use in coldstore environments. It can withstand temperatures as low as -40°C without cracking or losing its sealing properties, making it an ideal choice for cold storage applications.

Highly flexible
Neutral curing silicone is also highly flexible, which allows it to accommodate movement in the structure without cracking or losing its sealing properties. This is vital in coldstore construction, where temperature fluctuations and other factors can cause expansion and contraction of the structure, potentially leading to damage or failure of the sealant.

Easy to construct
Another advantage of neutral curing silicone sealants is that it is easy to apply and requires minimal surface preparation. This makes it an ideal choice for use in coldstore construction, where speed and efficiency are essential for meeting tight project deadlines and minimising downtime.

Application of Neutral Silicone Sealant

Neutral silicone sealants have a variety of applications, including:

Glass: It is ideal for sealing glass doors and windows, providing a watertight and airtight seal.

Exterior wall sealing: This sealant is ideal for sealing joints in building exterior walls, ensuring protection against water intrusion and air leakage.

Hygiene applications: Its mildew-resistant properties make it suitable for use in bathrooms and kitchens.

General repairs: From sealing gaps and cracks to bonding dissimilar materials, neutral silicone sealants are the go-to solution for a variety of repair tasks.

FAQ

Q: How is neutral cure silicone different from acid cure silicone?

A: The main differences lie in the curing process and byproducts. Neutral cure silicones are non-corrosive and low-odor, making them suitable for a wider range of surfaces, including sensitive materials. Acid cure silicones have a strong vinegar smell and can corrode certain metals and sensitive stone surfaces.

Q: What is the shelf life of neutral cure silicone sealant?

A: The shelf life can vary by brand, but many products are guaranteed for one year when stored properly in a cool, dry area. Some products may have a longer shelf life, but it's important to check the specific product packaging for the expiration date.

Q: Is neutral cure silicone sealant paintable?

A: No, standard neutral cure silicone sealants are not paintable. Paint will not adhere properly to the flexible, non-porous surface of silicone. If a paintable finish is required, a hybrid or acrylic sealant is a better option.

Q: Can neutral cure silicone be used on metal surfaces?

A: Yes, neutral cure silicone is highly recommended for use on metal surfaces because it is non-corrosive. This prevents staining, pitting, or rust on materials like aluminum, sheet metal, and other common building metals.

Q: Is neutral cure silicone suitable for wood and painted surfaces?

A: Yes, neutral cure silicone offers excellent adhesion to a variety of building materials, including wood, plywood, and painted surfaces. Its flexibility helps it accommodate the movement of these materials without cracking.

Q: How long does neutral cure silicone take to cure?

A: Neutral cure silicone generally cures more slowly than acid-cure versions. It typically skins over in 10 to 30 minutes, but a full cure can take 24 hours or longer, especially for thicker beads. Full adhesion strength may take up to 7 days to develop.

Q: Is neutral cure silicone waterproof and weather-resistant?

A: Yes, high-quality neutral cure silicones are 100% waterproof and offer excellent resistance to UV rays, weathering, and extreme temperatures. This makes them suitable for both interior and exterior applications.

Q: Can neutral cure silicone be used in cleanroom or sensitive environments?

A: Yes, neutral cure silicones are often preferred for sensitive environments due to their non-corrosive nature and low odor. They are sometimes used in food applications or medical device assembly, but specific ratings (like NSF) must be checked.

Q: Is clamping necessary when using neutral cure silicone as an adhesive?

A: When used as an adhesive, clamping or fixturing may be recommended to ensure optimal contact and a strong bond during the curing process. This is especially important for non-porous or heavy substrates.
