sealing for precast building
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.
Technical services:
Complete technical data and adhesion/compatibility tests are

Directions for use:
Before embarking on any work involving SMP551 silane modified
polyether sealant for precast concrete building, the safety data
sheet should be carefully studied by those carrying out the work.
All surfaces must be structurally sound, clean, dry and free of
oil, grease, asphalt, and any loose particles.
This product is strongly suggested to use primer PR103 before apply
the sealant.
Mask adjacent surfaces. Install approved backing material where
necessary.
Cut the nozzle to the required diameter.Apply sufficient sealant
into joint sides to ensure complete contact.
Tool in 10 minutes. Remove masking immediately after tooling.
Keep good ventilation during construction and cure.
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:
Avoid eye contact with uncured sealant, especially children. In
case of eye contact, flush eyes with water or obtain medical
attention immediately.
