| Solubility | POLYTONE PA 302/303 is soluble In n-Butanol, n–Propanol, Cellosolve and mixtures of these with aromatic hydrocarbons e.g. Toluene and Xylene. This resin is partially soluble in iso-propanol and insoluble in ethanol ,
aliphatic and aromatic hydrocarbons. . Under certain conditions the solutions forms reversible gels on standing. In order to achieve complete solubility in alcohol solutions , sometimes it is necessary to add small percentage of water or aromatic hydrocarbon solvent . For optimum solubility blends of alcohols and hydrocarbon solvents are required. |

| Characteristics | Infinite Solubiity in Ethanol and Higher Alcohols |
| Solubility | POLYTONE PA 351 shows excellent solubility in a variety of solvents that do not attack rubber stereos .
Under certain conditions the solutions forms reversible gels on standing and to avoid this, it is recommended to add small percentage of water or higher alcohols or aromatic hydrocarbon solvent. POLYTONE® PA 351 has infinite solubility in ethanol and higher alcohols. It is soluble in methanol at higher concentrations – 40% and above |
| Application/Industry | POLYTONE® PA 351 is an alcohol soluble non reactive polyamide resin in solid form suitable for flexographic printing inks. This resin exhibits good anti-blocking characteristics and finds use in specialized flexographic inks and release lacquers. Inks prepared from this resin have good adhesion to a variety of substrates, excellent solvent release properties, low odour and good nitrocellulose compatibility. |
