Rosin derivative

Melhi NLM

Melhi NLM resin is obtained from the distillation of rosin or modified rosin. It is a medium-hard, deep amber to dark brown thermoplastic acidic resin.

Key properties

The solubility and tackifying properties of Melhi NLM make it particularly useful in gravure inks, hot melt adhesives, mastic adhesives, fiberboard, and similar low-cost applications for which color is not important.

Applications

  • General purpose tackifier in low cost adhesives and sealants
  • Resin component in gravure inks having quick solvent release and dry time
  • Binder for fiber-containing products
  • Mastic adhesives for flooring and other concealed applications

Pastillated or flaked resins may fuse, block, or lump during hot weather months, if stored near sources of heat, if double or triple stacked, or if stored for prolonged periods of time.

These forms of resins are prone to gradual oxidation, some more so than others. This could result in darkening and/or could have an adverse effect on solubility in organic solvents.

Care should be taken to minimize opportunities for product oxidation throughout processing. Accordingly, we strongly recommend maintaining proper storage conditions and strict inventory control at all times, ensuring that the oldest material is used first.
