Title:
低ＶＯＣ塗料における材料およびオリゴマー
Document Type and Number:
Japanese Patent JP5868001
Kind Code:
B2
Abstract:
A coating composition comprises a thermosetting binder, comprising a crosslinker, a first, hard material having functionality reactive with the crosslinker, and a second, soft material having functionality reactive with the crosslinker. The first, hard material is a polymer, oligomer or compound, the first material having a glass transition temperature of at least 40° C., a number average molecular weight of 2000 or less, and an equivalent weight of 150 to 600 grams per equivalent of functionality reactive with the crosslinker. The second, soft material is a compound that is an amorphous mixture of four or more isomers, near isomers, and/or homologous structures and has from two to four functional groups that form thermally irreversible linkages with the crosslinker under cure conditions, wherein each functional group is separated from each other functional group by at least four atoms. The first, hard material may also have an equivalent weight of about 220 to about 850 grams per equivalent of functionality reactive with the crosslinker or with at least one of the plurality of crosslinkers under cure conditions and be a material, which, if reacted alone with the crosslinker or with the at least one of the plurality of crosslinkers, would form a film having a Tukon hardness of 16 or more, the second, soft material may also have an equivalent weight of 200 to 2000 grams per equivalent of functionality reactive with the crosslinker or with at least one of the plurality of crosslinkers under cure conditions and be a material, which, if reacted alone with the crosslinker or with the at least one of the plurality of crosslinkers, would form a film having a Tukon hardness of less than 4, while the coating composition forms a cured film having a Tukon hardness of from about 7 to about 12.
