6 2.The Performance of L-MODU TM for HMA use IDEMITSU L-MODU TM will bring Great Advantage for HMA!! 1.Excellent Sprayability even at severer conditions (12 Spiral, ΩSpray ) Page 7 2.Strong Bond Strength Saves up to approx.3% of HMA 3. Producing Low Temperature Sprayable HMA 4. Wide Formulation Ideas Page 8 Page 9 Page

7 (1)Excellent Sprayability L-MODU TM based HMA has Excellent sprayability even at severe conditions such as 12, ΩSpray. This feature is attributed to the controlled Mw and Mw distribution which is brought by originally developed metallocene catalyst. Spiral Spray Test (4gsm, 15m/min) L-MODU based ΩSpray Test (4gsm, 1m/min) L-MODU based LM-B () APAO based LM-A (5/4/1) APAO based APAO/TF=8/2 APAO/TF/oil=5/4/

8 (2)Higher Bond Strength L-MODU based HMA has good NW/PE bond strength and higher NW/NW bond strength compared with other type. This feature is attributed to excellent cohesion strength of L-MODU and anchor effect arising from appropriate crystallization speed after deeply penetrated to NW. 6 (PE/NW) T-Peel strength of each HMA (CD) 6 (NW/NW) T-Peel strength (gf/25mm) 5 1 Film destruction 5 1 NW destruction 3gsm Initial 3gsm Aged 4gsm Initial 4gsm Aged 5gsm Initial 5gsm Aged Formulation(BP/TF/oil) Application Temp. LM-A 5/4/1 145 SBS Market 15 APAO 5/4/1 16 Advantage : Saves up to approx.3% of HMA L-MODU can achieve gf T-Peel strength with 3gsm others 4.5gsm LM-A 5/4/1 145 SBS Market 15 APAO 5/4/1 16

9 (3)Sprayable at Lower Temperature L-MODU based HMA is sprayable at lower temperature and produces good bond strength as well. This feature is attributed to lower melting point of L-MODU. 6 (PE/NW) T-Peel strength of each HMA (CD) 6 (NW/NW) T-Peel strength (gf/25mm) 5 1 Film destruction 5 1 NW destruction 3gsm Initial 3gsm Aged 4gsm Initial 4gsm Aged 5gsm Initial 5gsm Aged Formulation(BP/TF/oil) Application Temp.
