BAIYUN SMP651 Silane Modified Polyether Sealant

For Prefabricated Construction

Characteristics

  • Environmental friendly: low VOC, nonpoisonous, no staining or corrosion to substrate
  • Paintable: can be paintedwith most coatings, outstanding compatibility
  • Excellent workability: single component, good extrusion between 4~40℃,very easy to tool
  • Outstanding adhesion: bondto most construction materials without primes
  • Movement Capability:±35%, exhibit stable performances during normal shape change from stretch and shearing of joint inside the constructions
  • Excellent physical properties: Excellent weather resistance, excellent resistance to aging

 

Applications

  • Sealing of building joints or cracks for indoors decoration (ceiling, kitchen, windows, walls)

Product limitation

This product 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 immersionor 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 available from Guangzhou Baiyun Technology CO.,LTD.

Staining test service is also provided for clients. Clients can send the substrates to us by mail (or other ways), then we will carry out the staining test and give the test report.

 

Storage and shelf life

12 months from date of manufacture when stored at or below 27ºC (80ºF) in the original unopened containers.

 

 

Repairs

Repairs should not be needed in ordinary situations. If sealant is damaged and needs repairs, please remove damaged parts and clean surfaces with isopropyl alcohol, then seal the damaged region with this product. SMP651 silane modified polyether sealant for prefabricated construction can firmly bond to cured silane modified polyether sealant.

Directions for use

Before embarking on any work involving SMP651 silane modified polyether sealant for prefabricated construction, 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 optimumadhesion 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.
