β-carboxyethyl acrylate (β-CEA) is a mixture of reactive esters, each of which contain both acrylate and carboxylic acid functionality in the same molecule. Referring to the included structural formula, this mixture contains some unreacted acrylic acid (n=0), along with higher adducts of acrylic acid (n=1,2,3...). The dimer (n=1), i.e. β-CEA, is the largest single component, and the average molecular weight is equivalent to that of the dimer. β-CEA will polymerize when exposed to sources of free radicals. Because of its carboxylic acid functionality, β-CEA is useful as an adhesion promoter.

EBECRYL® 89 is an acrylated amine primarily used as a hydrogen donor, or photo activator, in ultraviolet light (UV) curable coatings and inks. When used in formulations in combination with a photosensitizer (e.g. benzophenone), EBECRYL® 89 provides rapid UV cure response in air by mitigating the effects of oxygen inhibition at the coating or ink surface. Unlike conventional tertiary amines such as N-methyldiethanolamine, EBECRYL® 89 reacts to become part of the UV cured polymer, resulting in lower residual odor.

Tripropylene glycol diacrylate (TPGDA) is a difunctional reactive diluent with a branched alkyl polyether backbone. Polymerization occurs when.TPGDA is exposed to sources of free radicals. It is widely used as a primary diluent in the formulation of ultraviolet light (UV) and electron beam (EB) energy curable coatings and inks.

EBECRYL® 130 is a low viscosity aliphatic di-acrylate which polymerizes when cured by UV (ultra violet) light or EB (Electron Beam). Ebecryl®130 is particularly useful for increasing Tg. EBECRYL® 130 can be used as a pigment grinding resin for UV ink-jet inks
