Improve Crack Filler Sealants thanks to Styrene Block Copolymers

high performance modified asphalt crack sealants In order to prevent moisture from damaging pavements, roadway cracks must be filled with high performance modified asphalt crack sealants. But how can asphalt crack sealants be formulated?

Styrene block copolymers (SBCs), such as SBS and SEBS are the most frequently used polymers to modify asphalt performance and fulfill Crack Fillers requirements. SBCs are compatible with different asphalt grades and their thermoplastic character make them ideal as modifiers to bring excellent properties.

arrow  Excellent elasticity and ductility

You can increase the elasticity and ductility by adding Styrene Block Copolymers (SBC) to your formulation:

arrow  Increased adhesion to substrates

You can also reinforce the structure of sealant formulation when  using Styrene Block Copolymers.

SBC enable to maintain charge at higher elongations. It corresponds to an excellent adhesion to the substrate, even under higher deformation and stress.

arrow  Broad range of asphalt service temperature

Including Styrene Block Copolymers (SBC) in asphalt formulations can also extend the service temperature of crack fillers.

The sealants can be stable under high temperature conditions and can easily resist to pneumatics friction during high traffic situations.

Optimize Building & Construction Sealants with Styrene Block Copolymers

hydrogenated low viscosity copolymersSEBS based Hot Melt sealants are more and more used for Building & Construction. They show significant advantages, but can lead to cohesive strength issues.
To cope with this, hydrogenated low viscosity copolymers have been developed. They reinforce the thermoplastic web and enable to significantly improve the sealant cohesive strength.

arrow  Cohesion improvement

When including radial SEBS in the formulation, the adhesive cohesion of Hot Melt sealant for B&C is optimized thanks to increased lap shear in wood & peel in aluminum.

arrow  Improved weathering resistance

Radial SEBS brings a better temperature resistance, and enables to formulate sealants with excellent weathering resistance.

arrow  Best in class sealants rheology

Last but not least, sealants formulated with radial SEBS show a reduced hardness, for an improved rheology and processing.
