Application Number: JP,2021-130886
Category (FI): C09K3/00@R,C09J201/00,G01N13/00
Stage: PROBLEM TO BE SOLVED: To provide a wetting agent that can accurately measure surface free energy, a set thereof, a method for measuring the surface free energy of a polyolefin member using the wetting agent or the set thereof, and a method for bonding a polyolefin member using the method.SOLUTION: A wetting agent includes a plurality of mixed solutions. The mixed solutions each comprise two types of liquid compounds having different surface free energies, and the plurality of mixed solutions are different from each other only in the mixture ratio of the two types of liquid compounds. The two types of liquid compounds satisfy the following condition X. (Condition X): for respective liquids in which the mixture ratio (A/B) of a liquid compound A having a smaller surface free energy measured by the ring method and a liquid compound B having a larger one, of the two types of liquid compound, is 100/0, 80/20, 50/50, 20/80, and 0/100, when the surface free energies measured by the ring method are plotted for B/(A+B), the determination coefficient of a linear approximation of the plot is 0.92 or more.SELECTED DRAWING: None (Grant)
