International Classification:

B05D003/06
C08K003/00

US Classification:

427/407100, 427/558000, 524/589000

Abstract:

The dual cure coating composition requires both radiation and heat energy to cure and comprises a radiation curable component (a1), a thermally curable binder component (a2), and a thermally curable crosslinking component (a3). Radiation curable component (a1) is polymerizable upon exposure to radiation and comprises at least two functional groups (a11) comprising at least one bond activatable with radiation. Thermally curable binder component (a2) is polymerizable upon exposure to heat, and comprises (a21) at least two functional groups which are reactive with functional groups (a31), and a polydispersity of less than 4.0. Thermally curable crosslinking component (a3) comprises functional groups (a31) which are reactive with functional groups (a21). The invention further comprises methods of making coated surfaces that have both optimum porosity sealing and adhesion.

Abstract:

The dual cure coating composition requires electromagnetic radiation and heat energy to cure and comprises a radiation curable component (a1), a thermally curable binder component (a2), and a thermally curable crosslinking component (a3). Radiation curable component (a1) is polymerizable upon exposure to electromagnetic radiation and comprises at least two functional groups (a11) comprising at least one bond activatable with electromagnetic radiation. Thermally curable binder component (a2) is polymerizable upon exposure to heat and comprises (a21) at least two functional groups which are reactive with functional groups (a31) and no more than 5% by weight of aromatic ring moieties (a22), based on the nonvolatile weight of thermally curable binder component (a2). Third component (a3) comprises at least 2.0 isocyanate groups per molecule. The invention further comprises methods of making coated surfaces having both optimum porosity sealing and adhesion.

US Classification:

522/126000

Abstract:

The coating composition comprises a radiation curable component (a1), a thermally curable binder component (a2), a thermally curable crosslinking component (a3), and optionally, one or more reactive diluents (a4). Radiation curable component (a1) is polymerizable upon exposure to electromagnetic radiation and comprises at least two functional groups (a11) comprising at least one bond activatable with electromagnetic radiation. Thermally curable binder component (a2) is polymerizable upon exposure to heat and has at least two functional groups (a21) which are reactive with functional groups (a31). Third component (a3) comprises at least 2.0 functional groups (a31) which are reactive with functional groups (a21). The value of UV/TH, the nonvolatile weight ratio of the sum of radiation curable component (a1) and optional reactive diluent (a4) to the sum of thermally curable binder component (a2) and thermally curable crosslinking component (a3) is from 0.20 to 0.60. Also disclosed are coated surfaces having both optimum porosity sealing and adhesion.

Abstract:

The dual cure coating composition requires electromagnetic radiation and heat energy to cure and comprises a radiation curable component (a1), a thermally curable binder component (a2), and a thermally curable crosslinking component (a3). Radiation curable component (a1) polymerizes upon exposure to electromagnetic radiation, and comprises at least two functional groups (a11) comprising at least one bond activatable with electromagnetic radiation, and one or more isocyanate-reactive functional groups (a12). Thermally curable binder component (a2) polymerizes upon exposure to heat and has at least two isocyanate-reactive functional groups (a21) and substantially no functional groups (a22) having bonds activatable upon exposure to electromagnetic radiation. Third component (a3) comprises at least 2.0 isocyanate groups (a31) per molecule. The ratio of NCO groups to the sum of isocyanate-reactive functional groups (a12) and (a21) is less than 1.30. The invention provides methods of making coated surfaces that have optimum porosity sealing and adhesion.
