Benefits
Post-breakage Safety
Higher load capability sustains safety after glass broken.
Superior Edge Stability
Enhanced laminated glass delamination resistance and superior performance.
Enhanced Unit Strength
Suitable for oversized glass beyond 3200mm span.
Enhanced Interlayer Strength
Enables thinner glass to achieve same wind load request, reduce weight and costs.
Excellent Compatibility
Combined with family Clear, Acoustic, Storm, UV and Vanceva Colors series to achieve limitless possibilities on design.
Quality PVB Characteristics
Anti-UV function, high cohesiveness, stunning clarity, noise proof, and suitable for all kinds of glass including float glass, patterned glass, solar coating glass and low-e glass.
Testing
Salt Fog for Edge Blush & Delamination
Test glass were placed in 35 degree and exposed to salt fog. It shows higher performance in edge blush and less susceptible to delamination compared to normal PVB.
Sealant Compatibility
Durability Test
Humidity test & UV radiation test
3mm annealed glass+0.76 Saflex Structural+3mm annealed glass, 300*300mm size, total 3 pieces.
Test glass put into a container and heated to 100 degree, then maintained for 16 hours.
