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.
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.
POLYTONE PA 351 is compatible with ketonic, maleic, nitro cellulose, reduced phenolic and pure phenolic resins. However, compatibility with alkyds is only partial.
Available in 25 Kg bags.
Store under cool dry conditions. It is recommended that the material be used within 12 months from the date of manufacture.
