COATING AGENT AND NEEDLE HAVING SURFACE TREATED WITH SAID COATING AGENT

摘要

[Problem] The present invention provides: a coating agent having improved durability; and a needle coated with the coating agent. The coating agent according to the present invention comprises (1) 10 to 60% by mass of an amino-group-containing polyorganosiloxane (A) which contains at least one amino group per molecule, (2) 0.1 to 30% by mass of a condensation product (B) of a compound (B-1) represented by general formula (B) with a compound (B-2) having a group represented by general formula (B'), and (3) 10 to 89.9% by mass of a polydiorganosiloxane (C) (wherein the total amount of the amino-group-containing polyorganosiloxane (A), the condensation product (B) and the polydiorganosiloxane (C) is 100% by mass).
