Building and construction

In the regions of high economic growth, the number of construction projects is rising rapidly. The use of SBC adhesives and sealants in the Construction industry is increasing in both structural and non-structural applications.

More precisely, SBC adhesives and sealants are used to bond or join dissimilar substrates such as masonry, wood, plaster, paper, glass, etc... SBC adhesives and sealants can also address the growing use of pre-fabricated building elements and the expanding building insulation activities.

Durability, weathering performance, ease-of-application, temperature and water resistance are important characteristics required for building adhesives and sealants.

The examples below highlight how efficient SBC can be in distinct formulation type.

  • Strength improvement
  • Faster strength development
  • Lower viscosity than other polymer systems
  • Higher solids formulation capability for Low VOCs emissions
  • Wide range of structures for cohesive strength / viscosity balance
