The curret state of the adhesio performace betwee two kids of resis was evaluated by usig eleve kids of marketed resis accordig to the value of the tesile stregth. As a result, it was thought that the resi o the base side had to select either of resi of ABS, PA66, PA66+G3, PC or PC+G3 resis accordig to the use state of a real product whe the urethae was molded o the surface side of the product. It has bee uderstood that adhesio of betwee the PPO resi ad the urethae resi, ad POM resis with a o the whole difficult fabricatio becomes possible, sice the improvemet of the adhesio performace betwee resis two kids is examied with UV lamp. O the other had, adhesio the resi with a o the whole difficult fabricatio became possible by part heatig the adhesive iterface with the haloge lamp at about te secods. Especially, the adhesio performace of PP resis ad POM resis were improved up to about 8% of matrix tesile stregth i the maximum by part heatig with the haloge lamp. 5 Table 11 Table Table Urethae FS12S-18SAE 13) Fig. JIS K Fig. Table Table *1) *2) *3) *4) *5) *6)
