                          Figure 2. Example Process for Using UMEX Products

Precaution Against Mishandling

• The properties of resin may become worse when the UMEX products are used with the resin in excessive quantities due to being the modified low-molecular-weight polyolefin. Before using the UMEX products, confirm the optimal application amount.
• As shown in Table 2-b on page 7, the compatibility with certain molding resins is insufficient, therefore the transparency may be affected. Before using the UMEX products, confirm the compatibility with resins.

When UMEX 1010 is added to a mixture of ethylene propylene rubber and polypropylene, the surface of the molded resin is modified. The contact angle of liquid on the molded resin also decreases. Consequently, adhesion of the resin to a high polar paint (melamine type, polyurethane type, etc.) is improved dramatically.

Each formula sample 2 was washed using a neutral detergent and rinsed.􀀁
Methods:
Contact angle
The test pieces were kept at 23 °C, 65 % R.H., and then the contact angle of water on the sample was measured using a contact angle tester.ô€€
Adhesion to high polar paint
The sample was painted using a bar coater No.4 with a car paint (melamine type), and dried at 120 °C for 30 min. It was then kept at ambient temperature (20±15 °C) for 24 hours. Next, a right angled grid pattern was cut from the surface of the painted sample using a cutter. The intervals between the cut lines were 1 mm each with a total of 100 squares formed by the lines.
Then, an adhesive cellophane tape was stuck to the prepared sample. The tape was quickly peeled off at an angle of 45 degrees to the surface. The adhesion was determined by the number of squares that still remained. The larger the number of the squares on the surface, the better the adhesion to the high polar paint.
