What is a Styrenic Block Copolymer (SBC)?

SBC is a copolymer having two-phase structure of both hard segment and soft segment.

It behaves like an elastomer at ambient temperature and can be dissolved in solvents for blending and processing.

Radiative Properties Coatings made with Kraton SEBS polymers

exhibit excellent radiative properties. Testing

has shown best in class initial reflectance and

emittance. Samples prepared with the G1643

starting point formulation showed the following:

Reflectance: 0.89 ASTMC1549 Emittance: 0.88 ASTMC1371

Dirt Pick Up Resistance Coatings made with Kraton polymers:

exhibit excellent dirt pick up resistance for improved long term durability and

reflectance

have extremely low porosity and excellent water resistance

Water and stains cant penetrate the coating surface easily so coating

retains its color better

have excellent UV resistance in roof coatings and resist yellowing and staining

for better long term performance (G

grades)

Testing completed with coatings in an iron

oxide slurry for 500 hours show a roof

coating containing Kraton G1643 holds up

better than a typical acrylic formulation.

Acrylic standard G1643 coating
