EBECRYL® 8414 is a urethane acrylate developed for liquid energy curable thermoforming inks. Flexographic inks made with EBECRYL® 8414 exhibit excellent thermoformability with draws up to 1" without cracking, blistering, separation or loss of adhesion. This medium viscosity oligomer has good pigment wetting capability and ink performance.

EBECRYL® 3720 is a bisphenol A epoxy diacrylate that is the industry standard in performance and consistency. It exhibits light color and fast cure response. Films of EBECRYL® 3720 cured via exposure to ultraviolet light (UV) or electron beam (EB) demonstrate high surface hardness, gloss and excellent chemical resistance. EBECRYL® 3720 finds broad use in UV/EB applications, such as inks, coatings, and overprint varnishes and offers improved formulation stability.

EBECRYL® 8315 is an aliphatic urethane tetraacrylate diluted with the reactive diluent hydroxypropyl methacrylate (HPMA). Films of EBECRYL® 8315 cured by ultraviolet light (UV) or electron beam (EB) have a unique combination of hardness, toughness, flexibility, and abrasion resistance coupled with outstanding exterior durability properties. These performance properties make EBECRYL® 8315 ideal for applications such as paint protection, printed electronics, automotive interior film and embossing or thermoforming after cure.

EBECRYL® LEO 10601 is a modified epoxy acrylate that provides low extractables and low odor after UV or EB curing. EBECRYL® LEO 10601 exhibits good pigment wetting properties and produces UV offset inks exhibiting enhanced ink-water balance and low misting. EBECRYL® LEO 10601 can also be used to produce UV flexo inks with good flow, high gloss and high reactivity.

EBECRYL® 221 is a hexafunctional aromatic urethane acrylate oligomer which provides very fast cure response when exposed to ultraviolet light (UV) or electron beam (EB). Cured films of EBECRYL® 221 exhibit high hardness and solvent resistance.

VANCRYL® 450 is a high solids colloidal dispersion that can be neutralized with ammonia or other alkaline materials to provide an outstanding vehicle for corrugated printing ink applications. VANCRYL® 450, at 40% solids, reduces the cost in ink systems based on pre-neutralized colloidal acrylics. VANCRYL® 450 exhibits excellent black pigment grinding, and high drink in corrugated systems. This polymer, when neutralized with ammonia at 10% solids in water, has a viscosity of 150 cP, or about 40 seconds on a # 2 Zahn cup. It provides excellent transfer and printing at this low, economical solids level. Neutralization can be easily accomplished by a simple mixing of 100 parts polymer wet, 95 parts water, and 5 parts ammonia. This mixture produces a 20% solids colloidal emulsion with a viscosity of 6000 to 9000 cP. It can be used in black pigment dispersions as well as color letdowns for corrugated inks. VANCRYL® 450 is also an effective thickener for other formulations based on acrylic and styrenated acrylic polymers.

EBECRYL® 1365 is a hexa-functional silicone modified urethane acrylate diluted in 50% of EBECRYL® 160. EBECRYL® 1365 can be used to prepare UV/EB curable coatings with low surface energy providing anti-stain and easy-to-clean properties. Additionally EBECRYL® 1365 can be used as a processing agent in matt and excimer curable formulations, facilitating a uniform film creation which in turn significantly increases the process robustness.

EBECRYL® 745 is an acrylic polymer diluted 46% by weight with a 1/1 ratio of the reactive diluents 1,6-hexanediol diacrylate (HDDA)(1) and tripropylene glycol diacrylate (TPGDA) . EBECRYL 745 is used as the primary or modifying oligomer in ultraviolet light (UV) or electron beam (EB) curable formulations to increase adhesion on difficult substrates.

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® 8210 is an aliphatic urethane acrylate that exhibits low viscosity and high reactivity in ultraviolet (UV) light or electron beam (EB) curable coatings. Cured films of EBECRYL® 8210 demonstrate high hardness with good scratch, abrasion and chemical resistance. EBECRYL® 8210 also contains primary hydroxyl groups that can be utilized for dual cure polymerization. Dual cure can provide instantaneous tack-free coating surfaces via UV or EB exposure while reaction of the hydroxyl groups with a suitable isocyanate enables polymerization in regions of the coating where UV or EB energy exposure is insufficient or absent.

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® 4740 is a weather-stable aliphatic urethane acrylate having a low viscosity due to the allophanate structure. Formulations based on EBECRYL® 4740 exhibit high reactivity and yield tough and elastic polymers. Coatings formulated with EBECRYL® 4740 are characterized by very good chemical and mechanical resistances, scratch resistance, abrasion resistance, and high resistance to yellowing.
