Advantage


  1. Exceptional Weather Resistance
    Withstands UV radiation, ozone, and extreme temperatures (-50°C to +150°C), maintaining elasticity for 10+ years without cracking, yellowing, or degradation. Ideal for outdoor applications in (curtain walls) and exposed joints.
  2. High Elasticity & Movement Tolerance
    Exhibits 200–600% elongation at break with low modulus, absorbing thermal expansion, vibrations, and structural shifts in dynamic joints (e.g., building expansion gaps, window frames).
  3. Broad Substrate Compatibility
    Bonds strongly to glass, metal, ceramics, concrete, and most building materials without primers. Suitable for diverse surfaces in construction, automotive, and DIY projects.
  4. Rapid Room-Temperature Curing
    Forms a skin within 30–60 minutes and fully cures in 24 hours, reducing project downtime. No need for heat or special curing conditions.



Scope of Application

Neutral silicone sealants excel in diverse applications due to their non-corrosive curing mechanism and robust

durability. Ideal for construction, they seal curtain walls, windows, and sunrooms, withstanding UV radiation and

temperature swings from -50°C to +150°C without cracking. In kitchens and bathrooms, their mold-resistant

formula ensures long-lasting waterproofing for sinks, tiles, and showers. These sealants bond strongly to glass,

metal, and concrete without primers, while their high elasticity (200–600% elongation) absorbs vibrations in

automotive or marine applications. With low VOC emissions and rapid room-temperature curing, they suit both

commercial projects and DIY tasks, offering a balance of functionality, safety, and aesthetic versatility for decades

of reliable performance.
