Application

POLYTONE PA 303 is a polymeric fatty acid based co-solvent grade non reactive polyamide resin in solid form suitable for flexographic and gravure printing inks. This resin provides excellent resistance to grease and water, and good glossy sharp prints. It has excellent adhesion to treated polyethylene and other plastics. POLYTONE PA 303 has good flexibility and very good solvent release properties.

Solubility

POLYTONE PA 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.

Compatibility

POLYTONE PA 303 is compatible with ketonic, maleic, reduced phenolic and pure phenolic resins. However, compatibility with alkyds is only partial. Compatibility of POLYTONE PA 303 with nitrocellulose is much improved as compared to that of POLYTONE PA 302

Packaging: Available in 25 Kg bags

Shelf Life: Store under cool dry conditions. It is recommended that the material be used within 12 months from the date of manufacture

Outstanding Rub Resistance for Lasting Performance

This polyamide resin is specially designed to withstand mechanical abrasion, ensuring your coatings, inks, and adhesives maintain their quality over time. Its robust rub resistance extends the lifespan of finished surfaces, making it ideal for industrial applications where durability is essential.


Easy Compatibility with Solvents

The resins solubility in alcohol and ketone solvents simplifies its incorporation into various formulations. This versatility streamlines production processes in coatings, printing inks, and adhesives, guaranteeing uniform dispersion and enhanced performance.


Safe and Convenient Storage

To preserve product integrity, the resin should be stored in a cool, dry environment, away from direct sunlight. Its shelf life of up to 2 years ensures flexibility in inventory management, reducing waste and optimizing operational efficiency.
