Silicone sealants are a common type of adhesive and can provide valuable assistance whether waterproofing bathrooms, sealing window frames, or caulking structural joints. Common silicone sealants are classified as neutral or acidic, and the performance of the sealant has a direct impact on the final result. So, how do you choose the right silicone sealant?
1. Common Types of Silicone Sealants
(1) Acidic silicone sealant
Acidic caulk has better adhesion than neutral sealant but releases acetic acid during curing, which is corrosive to certain metals and substrates. It is suitable for non-corrosive materials such as glass and ceramics.
(2) Neutral silicone sealant
Neutral curing, and suitable for most building materials, with no adverse reactions or corrosion.
(3) High temperature silicone sealant
High heat resistance, and it can withstand high temperatures up to 315°C and has super oil resistance and waterproof properties.
2. How to choose the best silicone sealant product?
Choosing the right sealant should be based on the specific application, which can ensure the best construction effect, reduce maintenance costs, and improve project quality.
(1) High-Temperature Applications:
For industrial parts like engines, motor housings, and mechanical seals, it’s important to use sealants with excellent heat and oil resistance. We recommend Tengyu GT101 RTV High Heat Silicone Sealant, which offers outstanding oil and water resistance, can withstand temperatures up to 650°F (315°C), and endures heavy vibrations. It’s versatile and not limited by the size or shape of the sealing surface.
(2) Kitchen and Bathroom Sealing:
The kitchen and bathroom are more humid, which makes it easy to breed mold, not only affects the living environment to clean and beautiful, but also not easy for people’s health, so we must choose a special anti-mold silicone sealant. Both acidic and neutral types are available. For metal substrates, neutral anti-mold sealants are recommended.
For countertops and cabinet sealing, Tengyu TNS755 neutral anti-mold sealant is ideal. This 100% waterproof sealant offers up to 10 years of mold protection and resists water damage within only 30 minutes. It’s perfect for sealing countertops and cabinets without corroding metals or marble surfaces.
For the kitchen and bathroom sealing, we suggest Tengyu TNS753 Sanitary Silicone Sealant and TAS685 acidic anti-mold sealant. TNS753 is a 100% silicone sealant with high performance, excellent adhesion, and strong resistance to UV degradation and weathering. It is great for sinks, bathtubs, showers, fixtures, countertops, backsplashes, and plumbing applications.
TAS685 is a premium 100% silicone sealant offering 20 years of mold and mildew protection. It resists cracking and shrinking, providing a durable, permanent, 100% waterproof seal.
(3) Door and Window Sealing:
For doors and windows, sealants with excellent weather resistance and UV stability are essential to withstand wind and rain while avoiding aging. We recommend Tengyu neutral TNS771 silicone window sealant, specially formulated for doors and windows, which adheres well to glass and most building materials, with superior weather and aging resistance.
If fire resistance is needed, consider TNS784 fireproof silicone sealant, rated for up to 4 hours of fire resistance. It also features excellent resistance to ozone, UV radiation, and extreme temperatures. It is suitable for fire-rated curtain walls, building facades, and expansion joints.
