7 M77 resin ski industry Requests: Short cycle times long shelf life Good bonding properties with metal Higher viscosity vs existing matrix 1 CAP Folie 2 HexPly M77* 3 PUR-core* 4 HexPly M77* 5 wood core 6 HexPly M77* 7 PE running surface 8 Steeledge M77 = lean manufacturing 6

8 M77 resin biggest benefits for ski industry Traditionally short cycle system implies 1 to 5 days shelf life Shorter process cycle than former typical prepreg M77 process vs. former typical prepreg system new M77 Reduction of set up temp. by 10 C former system 120 Prepreg Temp Nearly 20% cycle time reduction Demoulding at higher temperature time x10= sec M77 ~ 25% higher output, ~ 5% lower energy costs

9 M77 resin : process adapted for automotive parts short cure cycle: 2 min at 150 C or 1 min 30 at 160 C demould in hot conditions Long shelf life (6 weeks at 23 C). control flow even under high pressure (up to 100 bars) giving suitable with standard compression tools No fridge M77 adapted for high production rate 8

10 M77 resin : process adapted for automotive parts Typical cure cycle M77 cure cycle for 3mm thick part Températur re ( C) (bar) Pressure bottom mould surface température middle of part temperature time (s) Mould closing (10 ) Mould opening and part ejection(10 ) 0 pressure M77 adapted for high production rate 9

11 Mechanical performance on M77 prepreg 200gsm twill 2X2 3k carbon fabric 150 gsm unidirectional carbon tape Time (min) cure time (min) 98% shorter typical prepreg resin for structural automotive part M77 High mechanical performance obtained with shorter cure cycle 1

12 Electrocoating treatment simulation Simulate electrocoating treatment by measuring the flexural Modulus at 200 C 3,5 flexural Modulus at 200 C (Gpa) 3 2,5 2 1,5 1 0,5 0 SMC M77 Good residual stiffness at 200 C 11

13 M77 potential for automotive parts Mechanical performance after typical electrocoating treatment (30min at 200 C) 700,0 600,0 500,0 400,0 300,0 200,0 100,0 0,0 flexural strength (Mpa) - 6% 35,0 30,0 25,0 20,0 15,0-21% - 12% SMC SMC after30' AT 200 C M77 M77 after 30' at 200 C 10,0 5,0 0,0 flexural Modulus (Gpa) - 6 % SMC SMC after 30' at 200 C M77 M77 after 30' at 200 C Low influence of electrocoating treatment on mechanical performance 1

14 M77 resin : potential for automotive parts Short time cycle Good mechanical properties M77 Reach conform Long shelf life A unique system for high production rates 1
