Neutral silicone sealants are high-performance elastomeric sealants that cure through exposure to atmospheric moisture to form durable, flexible seals and bonds. They are commonly used for weatherproofing, glazing, expansion joints, and other construction sealing needs.
Flexibility - Ability to stretch and compress without losing adhesion
Durability - Resistant to UV, ozone, moisture, and extreme temperatures
Versatile adhesion - Bonds to glass, metals, plastics, masonry, wood
Low odor - Releases minimal acetic acid during curing
Proper application technique is important when using neutral silicone sealants. First, all surfaces should be cleaned, dried, and primed for optimal adhesion. Cut the sealant nozzle tip to the desired bead size. Load the sealant cartridge into a caulking gun and apply steady pressure to all joints and seams. Tool the silicone for a smooth finish. Allow 1-2 days for full cure time.
Compared to acetic cure silicone, neutral silicone provides some significant benefits:
Lower odor during cure - Acetic silicone gives off strong vinegar-like odor as it releases acetic acid when curing. Neutral silicone has minimal odor.
Better adhesion to a wide variety of building materials like metals, glass, and plastics. This versatility makes neutral silicone suitable for more applications.
Enhanced flexibility and elasticity allows neutral silicone to accommodate more joint movement.
Shorter tack-free time so surfaces can be put back into service more quickly.
In summary, neutral silicone sealants deliver versatile, flexible, waterproof sealing for construction and industrial applications. Their well-balanced performance makes them a reliable choice.
Conclusion: For durable weatherproofing seals in high movement joints, choose a premium neutral silicone sealant like those offered by GORVIA. Our expertise helps identify the right silicone for your project.
