MKOREZ® MK-140

MKOREZ® MK-140 is made from highly purified monomers such as styrene and/or alpha methyl styrene. This pureness of raw materiaals can make the resin has water white color with high aromaticity than that of conventional hydrogenated resins at the same time. This has good heat stability and excellent potential as a modifier in high shear adhesive compounds based on SBCs (SIS,SBS or SEBS etc) This can be also used as additive in other kinds of adhesive or various elastomeric compounds as well.

Storage & Handling

Storage Conditions
  • Pelletized forms of resins may lump.
  • to store inside and keep cool condition (In case of softening point over 100°C, max 30°C / In case of softening point below 100°C, max 25°C)
  • not to overly stack the materials
  • to avoid sunlight
  • Especially, low softening point resins(below 100°C) has a higher possibility of blocking due to the nature of product. Therefore, we strongly recommend that keep storing in more strict conditions.
  • The shelf life can be affected by storage and handling conditions. When products are stored in the original unopened container in an enclosed area and protected from contamination,moisture and extreme temperatures, the shelf life of MKOREZ ® MK-140 is two years from the date of manufacture .
