| What are some ways to improve the shear adhesion failure temperature (SAFT) and shear properties of SIS (styrene-isoprene-styrene)-based pressure-sensitive adhesives (PSAs)? |
| |
| Shear properties of SIS-based PSAs can be improved by using higher melting point tackifiers (Eastotac H-130R or Eastotac H-115R vs. Eastotac H-100R, for example), by increasing the amount of polymer in the formulation and/or by reducing the concentration of plasticizing oil. The percentage tackifier is generally not as important as its softening point. |
