The storage and application of PU sealant affect the shelf life and usage. The shelf life of all given is understood to be 12 months from the date of manufacturing. It is to be kept in temperature from 5°C to
In the specific case of India, since practically the temperature rises up to 45°C to 50°C, the sealant is usable. Due to extreme heat or humidity, the skin formation time of the same may be little faster in those specific conditions. Although, the sealant can still be used with effectiveness.
What Is A Polyurethane Sealant?
PU joint Sealant is basicly an insulating and grouting material. They can have ±25% movement capability. The flexibility ratio can be further increased as required. It is used for sealing, filling gaps, keeping water and air away from joints, absorbing the natural movements of building materials and increasing aesthetics.
