Key features
Inert modified polyester resin for UV-PSA, good adhesion and high peel strength, tackifiing resin, providing a good balance of tack and shear properties
Co-resins are used in formulations to increase the performance of primary oligomers, when used alone. Typical applications include:
Screen Inks
Flexo Inks
Offset Inks
Industrial coatings, especially on plastics
Pressure sensitive adhesives
How do co-resins influence these systems?
By adding a Co-resins to a given formulation, the following properties are influenced:
Adhesion capability on different substrates
Crosslink density and network structure pigment wetting
Cure speed and productivity
Flexibility of the overall system
Mechanical and thermal performance
Offset ink behaviour
By participating in or modifying the crosslinking process, co-resins help tailor the final polymer network architecture, which directly determines properties such as adhesion and flexibility.
How are co-resins used in coatings?
In coatings, co-resins function as part of the binder matrix, interacting with oligomers and monomers. They are used in several UV-curable industrial and protective coatings, wood and plastic coatings. Their role includes:
Control film shrinkage
Improve adhesion
During curing, the binder undergoes crosslinking to form a three-dimensional polymer network, which determines mechanical strength, adhesion, and chemical resistance.
What role do co-resins play in printing inks?
Co-resins are critical in printing ink formulations, where they enhance:
