Storage & Shelf Life

Stored properly in a dry and well-ventilated place below 30℃.
Usable life is 12 months in original package.
For more information refer to package.

Safety & Disposal

Be careful the application temperature. When the substrates surface is over than 50℃, it is easy to cause fast-cure or bubbles. When the substrates temperature is lower than 5℃, it is easy to slow-cure. And also, a layer of indiscernible fog is formed on the surface of substrates, which affects the cohesive, so it should be wiped with a piece of dry cloth or heat blow drier.


Minimum joint width of 6 mm.
1.Minimum joints depth of 6 mm.
2.For larger joints the width of the joint should be greater than the sealant depth,recommended the ratio of joint width to depth is 2:1.
3.Avoid 3 sided adhesion: Apply backer rod or bond breaker tape in the base of the joint to ensure the sealant is only bonded to the sides of the joint and is free to move to its full capacity under joint movement.
