Examples
Embodiment 1
[0107] As shown in [Table 1], the coating material for medical devices of Example 1 contains a main agent, a radical scavenger, a curing agent, and a colorant.
[0108] As the main ingredient, 100 parts by mass of fluorinated polyol was used. Specifically, Fclear (registered trademark) KD3100 (trade name; manufactured by Kanto Denka Kogyo Co., Ltd.) was used.
[0109] As a radical scavenger, 5 parts by mass of hydroquinone was used.
[0110] As a curing agent, 24 parts by mass of isocyanate was used. Specifically, Trixene BI 7960 (trade name; manufactured by Baxenden Chemicals Co. Ltd.) was used. Trixene BI 7960 is a blocked isocyanate comprising dimethylpyrazole (DMP) as a blocking agent.
[0111] As a coloring material, 20 parts by weight of titanium dioxide (titanium white) was used.
[0112] By mixing these components, the coating material for medical devices of Example 1 was produced. The coating material for medical equipment of Example 1 is a one-component reactive...
Embodiment 2
[0119] The coating material for medical devices of Example 2 was produced in the same manner as the coating material for medical devices of Example 1 except that 5 parts by mass of benzoquinone was used instead of hydroquinone in Example 1 as a radical scavenger.
[0120] Mark 2 and the test sample in Example 2 were manufactured in the same manner as in Example 1 except that the paint for medical devices of Example 2 was used instead of the paint for medical devices of Example 1.
Embodiment 3
[0122] The coating material for medical equipment of Example 3 was produced in the same manner as the coating material for medical equipment of Example 1 except that the types of the main agent and curing agent and the content of the colorant were changed, and a solvent was used for mixing.
[0123] As the main ingredient, 20 parts by mass of epoxy polyol was used instead of the fluorinated polyol in Example 2. Specifically, as the epoxy polyol, EXA-8183 (trade name; manufactured by DIC Corporation) was used.
[0124] As a curing agent, 5 parts by mass of non-yellowing xylylene diisocyanate was used instead of the isocyanate in Example 2. Specifically, Takenate (registered trademark) 500 (trade name; manufactured by Mitsui Chemicals, Inc.) was used as the non-yellowing type xylylene diisocyanate.
[0125] The content of the colorant was set at 35 parts by weight.
[0126] In the medical device coating material of Example 3, the above-mentioned main ingredient, radical scaven...
