Product limitation
SMP851 silane modified polyether sealant for precast concrete building should not be used, applied or not recommended :
· In conditions above 80℃.
· In structural glazing applications.
· In totally confined spaces as the sealant requires atmospheric moisture for cure.
· In applications for immersion or always wet conditions.
· On substrates that can extrude grease, plasticizer or solvent.
· On substrates made of polypropylene, polyethylene and polytetrafluoroethylene.

Directions for use
Before embarking on any work involving SMP851 silane modified polyether sealant for precast concrete building, the safety data sheet should be carefully studied by those carrying out the work.
1.All surfaces must be structurally sound, clean, dry and free of oil, grease, asphalt, and any loose particles.
2.Mask adjacent surfaces. Install approved backing material where necessary.
3.Cut the nozzle to the required diameter. Apply sufficient sealant into joint sides to ensure complete contact
4.Tool in 10 minutes. Remove masking immediately after tooling.
5.Keep good ventilation during construction and cure.
6.To confirm optimum adhesion on either a porous or nonporous surface, adhesion testing should always be carried out prior to the commencement of any project and be carried out at regular intervals during the project.
Cautions
SMP851 silane modified polyether sealant for precast concrete building is non-hazardous when fully cured. Avoid eye contact with uncured sealant, especially children. In case of eye contact, flush eyes with water or obtain medical attention immediately.
Standard
SMP851 Sealant for industrialized housing meets or exceeds the requirements of Q/BYHG 2-2014.
