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.Table 7. Effects of Surface Modification on Polyolefin

Materials:
According to Formulas 1 to 2 described in Table 7, each of the compounds was kneaded using a twin-screw extruder at 210 °C, and then molded using an injection molding machine (nozzle temperature: 210 °C) . Each formula sample 1 was unwashed.
Each formula sample 2 was washed using a neutral detergent and rinsed.ô€€
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.6. Improvement in Molding Processability on ABS Resin UMEX 110TS and UMEX 1010 improve fluidity and release properties of ABS resin when one of the products is added to the resin.

See Table 3.7. Improvement in Adhesive Strength of Hot Melt Adhesives
When either UMEX 100TS or UMEX 110TS is added to hot melt adhesives, the workability of the adhesives is enhanced because their melt viscosity decreases compared with a mixture of a viscosity depressant (low molecular polyolefin type), including polyethylene wax (Formula 3), and what is more, the UMEX products improve the peel strength and creep resistance.Table 9.

Melt viscosity
Melt viscosity was measured at 200 °C using a Brookfield-type viscometer.

Creep resistance (JIS K 6859)
Two polypropylene films were joined together with the sample (the area of adhesion was 25 mm wide and 25 mm long, the length of non-adhesion films was 75 mm). Then, one of the non-adhesion films was fixed. A 500 g weight was hung on another non-adhesion film, and then the time required for its peeling off and completely dropping from the fixed film was measured. The measurement was conducted at 70 °C.8. Increase in the Softening Point of Asphalt
