| STABILITY |
The
stability depends upon dissolved oxygen and MEHQ inhibitor.
The presence of oxygen is necessary for inhibitor to
prevent polymerization. |
|
APPLICATIONS
|
|
2-Hydroxyethyl
Methacrylate is used in light curing polymer system
and high performance coatings for lasting high gloss
against cratching, solvents and weathering. It is used
in paint resins and emulsions, binders
for textiles and paper. It is used as a adhesion promoter
for metal coatings.
