Thixotropic, radiation curable compositions

Patent ·
OSTI ID:7351553
A reactive metal oxide or metal hydroxide, such as ZnO, MgO, HgO or Ba(OH)/sub 2/ and acrylic or methacrylic acid are added to a liquid, hydrophobic, essentially solvent-free coating vehicle capable of being cured by high-energy radiation. The resulting coating composition, as compared to the vehicle alone, can be cured with lower radiation doses, is less susceptible to oxygen inhibition of curing with ionizing radiation and exhibits a thixotropic viscosity which prevents excessive penetration of the coating into porous substrates and contributes non-drip, low-flow characteristics to the composition.
