Features
• Weatherability; offers resistance to sunlight, rainwater, snow, ozone and extreme temperatures.
• Durability; the cured sealant can maintain its elasticity in temperatures of -50ºC to 150ºC without hardening, cracking or degrading.
• Reasonable operation time; allows operators greater control of application and tooling time.
• No slumping; can be used for the sealing of vertical and wide joints.
Application
Dow Corning 168 weatherproof silicone sealant is suitable for construction curtain wall structural components assembly
STEP 1

Applications
Structural sealant high strength, can withstand large loads, and resistance to aging, fatigue resistance, corrosion resistance, performance in the expected life of stability, suitable for strong structural parts of the adhesive bonding.
Non-structural adhesive strength is low, poor durability, only due to the general, temporary nature of the adhesive, sealed, fixed, can not be used for structural bonding.
