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 6 7 5 4 3 2 1 8 M77 = lean manufacturing 6
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 160 150 M77 process vs. former typical prepreg system new M77 Reduction of set up temp. by 10 C 140 130 former system 120 Prepreg Temp. 110 100 90 80 70 60 50 40 30 20 10 0 0 6 12 18 24 30 36 42 48 54 60 66 72 78 84 Nearly 20% cycle time reduction Demoulding at higher temperature time x10= sec M77 ~ 25% higher output, ~ 5% lower energy costs
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
