    • The present invention is directed to providing a safe medical adhesive, a cured body of which is hard to be degraded and decomposed and thus stable and the cured body generates less amount of acid, aldehyde, etc. due to degradation/decomposition. The medical adhesive includes a hydrophilic urethane prepolymer (UP) obtained by reacting a polyisocyanate component (A) containing a fluorine-containing non-aromatic polyisocyanate compound (A1) as an essential ingredient and a polyol component (B) containing a hydrophilic polyol (B1) as an essential ingredient, wherein a chlorine content in a chlorine-containing organic compound based on the weight of the hydrophilic urethane prepolymer (UP) is 0.005 wt % or less.
    • 本发明旨在提供一种安全的医用粘合剂,其固化体难以降解和分解,因此稳定,固化体由于降解/分解而产生较少量的酸,醛等。 医用胶粘剂包括通过使含有含氟非芳香族多异氰酸酯化合物(A1)作为必需成分的多异氰酸酯成分(A)与含有亲水性多元醇(B1)的多元醇成分(B)反应而得到的亲水性氨基甲酸酯预聚物(UP) )作为必要成分,其中,基于亲水性氨基甲酸酯预聚物(UP)的重量,含氯有机化合物中的氯含量为0.005重量%以下。
