- Formulation Guideline
Coatings can be adjusted to appropriate viscosity for the application with additional HDDA(1) or the addition of other standard reactive diluents such as dipropylene glycol diacrylate (DPGDA)(1) , isobornyl acrylate (IBOA)(1) and trimethylolpropane triacrylate (TMPTA)(1) as well as solvents such as butyl acetate.; EBECRYL® 4690 is compatible with most acrylate monomers and oligomers. Because of the many possible combinations with reactive diluents and solvents, the compatibility must be tested in each individual case.; UV curing of coatings formulated with EBECRYL® 4690 requires the addition of standard commercial photo initiators. Typical levels are 4 - 6% although this may vary to meet the reactivity requirements for the application. In the case of EB curing, a low oxygen atmosphere must be ensured to avoid surface inhibition. Lower gloss coatings can be produced using standard matting agents. Care should be taken with respect to sedimentation which may cause the coating to gel prematurely
- Performance Highlights
UV/EB cured coatings based on EBECRYL® 4690 are characterized by the following performance properties: ·; Very good mechanical properties ·; High abrasion resistance ·; Good chemical resistance; Low yellowing; Robust outdoor resistance (weathering); The actual properties of UV/EB energy cured products also depend on the selection of other formulation components such as reactive diluents, additives and photo initiators.
- Compatible Substrates and Surfaces
- Wood
- Known For
EBECRYL® 4690 is designed for use in the formulation of UV/EB energy curable coatings for application by roller coating, spraying and curtain coating on wood, cork, furniture, paper, parquet plastics and film. It is a very suitable choice for outdoor building and cladding applications.
