Offset & Lithographic Printing

EBECRYL® 450 is a fatty acid modified polyester hexaacrylate. Because of the special structure of the backbone and the high acrylic functionality, EBECRYL® 450 provides the proper hydrophilic-lipophilic balance necessary for lithography, combined with high reactivity when cured by ultraviolet light (UV) or an electron beam (EB). Lithographic inks based on EBECRYL® 450 display outstanding printing qualities, including excellent ink transfer, good dot definition, and proper tack and rheological properties.

EBECRYL LEO® 10103 is a multifunctional acrylate that in the presence of an amine synergist can enable the UV curing of printing inks and coatings without, or with only a minimal amount, of photoinitiator. The elimination or reduction of photoinitiator decreases the potential for migration in indirect food contact applications. EBECRYL LEO® 10103can be used for low migration over print varnishes along with flexographic and offset inks in the entire color range, including white. EBECRYL LEO® 10103 at 10-20% by weight in a coating or ink can provide a good balance of surface and through cure.

EBECRYL® 3700-20T is the bisphenol A epoxy diacrylate, EBECRYL 3700, diluted 20% by weight with the reactive diluent trimethylolpropane triacrylate (TMPTA)(1), to provide a lower viscosity, easier handling product. EBECRYL 3700- 20T exhibits very fast cure response and low odor. Films of EBECRYL® 3700-20T cured by ultraviolet light (UV) or electron beam (EB) demonstrate high gloss, surface hardness, scratch resistance, and excellent chemical resistance.

EBECRYL® 3721 is a modified bisphenol A epoxy diacrylate resin. EBECRYL® 3721 demonstrates increased toughness in ultraviolet light (UV) or electron beam (EB) energy cured coatings compared to standard epoxy acrylates while maintaining high reactivity and superior chemical resistance.

SIPERNAT® 320 DS is a highly dispersible silica powder with high surface area, commonly used in coatings, adhesives, and sealants. It improves rheology, reduces viscosity, and provides enhanced flow properties. It is widely used in industrial and consumer goods applications for improving the performance and consistency of the final product.

EBECRYL® 830 is a polyester hexa-acrylate that exhibits fast cure response and moderate viscosity. Films of EBECRYL 830 cured by ultraviolet light (UV) or electron beam (EB) demonstrate good abrasion and scratch resistance, solvent resistance and hardness.

EBECRYL® 1657 is a purified version of EBECRYL® 657, a tetrafunctional polyesteracrylate oligomer and was developed for applications where low odour and low extractability are required. EBECRYL® 1657 may be cured by ultraviolet light (UV) or electron beam (EB) and displays outstanding lithographic behaviour, pigment wetting properties and low irritancy.

TEGO® Glide 432 shows very good slip and substrate wetting properties. It is highly recommended for radiation-curable coatings.

EBECRYL® 230 is an aliphatic urethane diacrylate characterized by its light color and low viscosity. Films of EBECRYL 230 cured via exposure to ultraviolet light (UV) or electron beam (EB) are soft and flexible, and are resistant to yellowing. EBECRYL 230 is often used as a modifier to improve the flexibility of finished formulations.

EBECRYL® 3411 is a fatty acid modified bisphenol A epoxy diacrylate resin with relatively low viscosity, good flow and leveling, and excellent pigment wetting properties. Films of EBECRYL® 3411 cured by ultraviolet light (UV) or electron beam (EB) demonstrate high gloss, a degree of toughness and good chemical resistance.

EBECRYL® 870 is a fatty acid modified polyester hexaacrylate. Because of the special structure of the backbone and the high acrylic functionality, EBECRYL® 870 provides the proper hydrophilic-lipophilic balance necessary for lithography, and high reactivity when cured by ultraviolet light (UV) or an electron beam (EB). Lithographic inks based on EBECRYL® 870 will also display outstanding printing qualities, including excellent ink transfer, good dot definition and proper tack and rheological properties.

Acrylated Dipentaerythritol (DPHA) is a multifunctional reactive diluent that polymerizes when exposed to sources of free radicals. DPHA is particularly useful in ultraviolet light (UV) and electron beam (EB) curable coatings and inks where improved cure response, hardness, and scratch/abrasion resistance are desired. DPHA is composed predominately of the penta- and hexa-acrylate esters of dipentaerythritol, with the overall composition represented by the included chemical structure.
