Weather Resistant Radiation Curable Monomers and Oligomers for Exterior Applications

The weather resistance of an exterior coating is one of the main properties required by the
end-user. The backbone structure of several monomers and oligomers has been investigated and
subjected to accelerated weathering tests. This ongoing study has shown that most of these acrylates, which are free from light stabilizers, can stand more than 5000 hours in a xenon test chamber and more than an equivalent of three years in Florida. Although the testing was conducted in accordance with automotive test standards, these products are suitable for any application requiring superior outdoor durability. The physical properties and weathering data of the new oligomers and monomers will be presented.
