This printing ink toughener is composed of polyester resin and acrylic resin. It works as functional binder additive for printing ink. It promotes continuous and uniform ink film formation during drying or curing process. It improves adhesion between ink film and different substrates, and increases flexibility to prevent cracking or peeling when printed material is bent. It is widely used in solvent-based, water-based printing ink and coating formulations.

Product Detail

Product Detail PageChemical IdentityPolyester resin has excellent flexibility and adhesion on plastic and metal substrates. Acrylic resin provides good weather resistance, gloss and film-forming property. The combination can be applied separately or blended. Both resins have good compatibility with common ink solvents, pigments and fillers. They can be mixed in the ink grinding and dispersion stage under standard ink manufacturing process.

Key PerformanceIt improves continuous film formation of printing ink and reduces pinholes and film defects. It strengthens ink adhesion to plastic film, paper, metal and composite substrates. It boosts ink film flexibility to resist cracking during folding and stretching. It balances surface gloss and abrasion resistance of printed layer. It shows stable compatibility with pigments and will not affect color development. It improves storage stability of finished ink.

ApplicationsMain applications include various printing inks. Typical end products: gravure ink, flexographic ink, screen printing ink, surface printing coating and packaging printing ink. Suitable for packaging printing, label printing, plastic film printing and paper printing formulations that require good film formation, adhesion and flexibility.

Storage & HandlingStore polyester and acrylic resin in sealed original bags or drums in cool, dry and ventilated warehouse. Recommended storage temperature 10-30℃. Keep away from fire and heat sources for solvent grade products. Avoid direct sunlight and high humidity. Prevent dust inhalation during powder handling. Reseal tightly after opening.
