AREAS OF APPLICATION
Sikaflex®-265 is designed for direct glazing applications in both the OEM and repair markets. Owing to its good tooling properties and enhanced weathering stabilization, the product may be used for exterior joints.
Seek manufacturer’s advice and perform tests on original substrates before using Sikaflex®-265 on materials prone to stress cracking.
Sikaflex®-265 is suitable for experienced professional users only. Test with actual substrates and conditions have to be performed to ensure adhesion and material compatibility.
CURE MECHANISM
Sikaflex®-265 cures by reaction with atmospheric moisture. At low temperatures the water content of the air is generally lower and the curing reaction proceeds somewhat slower.
CHEMICAL RESISTANCE
Sikaflex®-265 is generally resistant to fresh water, seawater, diluted acids and diluted caustic solutions; temporarily resistant to fuels, mineral oils, vegetable and animal fats and oils; not resistant to organic acids, glycolic alcohol, concentrated miner
