EBECRYL P115

Product Details

EBECRYL P115 is a copolymerizable amine used as a hydrogen donor, or photoactivator, in ultraviolet light (UV) curable coatings and inks.  When used in formulations in combination with a photosensitizer (e.g. benzophenone), EBECRYL P115 provides rapid UV cure response in air by mitigating the effects of oxygen inhibition at the coating or ink surface.  Recommended levels are from 5 to 15% based on the total formulation, usually combined with 3-5% photosensitizer.  EBECRYL P115 can be used with EBECRYL P39 (a polymeric benzophenone derivative) to produce UV cured coatings and inks with low residual odor.
 
EBECRYL P115 is characterized by: 

• Light color
• Low viscosity
• Improved stability vs. conventional tertiary amines
• Low volatility

 
UV/EB cured products based on EBECRYL P115 are characterized by the following performance properties:

• Excellent UV cure response
• Reduced odor
• No surface migration of amine
• High gloss

 
The final properties of UV/EB cured products also depend on the selection of other formulation components such as reactive diluents, additives and photoinitiators.

Typical Applications

Formulated UV curable products containing EBECRYL P115 may be applied via direct or reverse roll, offset gravure, metering rod, slot die, knife over roll, air knife, curtain and immersion and spin coating methods, as well as flexographic and screen printing. 

EBECRYL P115 is recommended as a reactive co-initiator in the following applications:

• Overprint varnishes
• Screen and flexo inks
• Wood topcoats
• Clear coatings on paper and plastics
• Pigmented coatings
