Gretack GP-120

GRETACK GP-120 is a water–white fully hydrogenated hydrocarbon resin with the characteristics of low melt-viscosity and narrow molecular weight distribution with excellent thermal stability, low odor, and water-soluble polymers like SIS and APAO. It is primarily used in hot-melt adhesives (HMA), hot melt adhesives for hygiene products (HMPSA).

Key Characteristics:

Colorless and transparent.

Odorless and low volatility

Excellent heat stability

Excellent compatibility with APAO and SIS

Well-balance adhesive properties, including tack, adhesion and cohesion.Specifications

Storage

Inside storage is recommended and keep at temperature not exceeding 30oC. Pelletized forms of resins may block or lump in hot weather climates or if stored near heat sources. Resins are prone to gradual oxidation, some more so than others. This could result in darkening and/or it could have an adverse effect on the solubility of the resin in organic solvents or on its compatibility with polymers.
