My Technical Paper Presentation at , ( MKVS ) ,( 28. – 30. October 2013 ), Presentation Transcript

  • 1. My Technical Paper Presentation at , Munich Adhesives and Finishing Symposium ( MKVS ) , ( 28. – 30. October 2013 ), at Sheraton Munchen Arabellapark Hotel , in Munich , Germany. On Technical Developments in HM and HMPSA from the Emerging Market of India
  • 2. Shrikant Athavale CEO Prathith Consultants PUNE – 411038, Maharashtra , India
  • 3. This is a Presentation on latest Developments in HM and HMPSA from Emerging Market in India. I am going to discuss about two such developments . The developments that , I am going to address are as follows.
  • 4. Part One : “ Surgical tape , Water proof , with Hypo allergic HM PSA ” Part Two : “A Innovative method of manufacture of PVC Insulation Tape, using HM PSA “
  • 5. Let us Discuss about Part One now
  • 6. Surgical Tape ( water proof ) , with Hypo allergic HM PSA
  • 7. This is a Innovative method of manufacturing , Surgical tape , Water proof , with Hypo allergic HM PSA , similar to Band Aid .
  • 8. Advantages  Very light weight Film of Poly Urethane,  in Human Skin of color .  Higher production speeds due to innovative Coating mc design.  The Product is highly cost efficient, owing to , Lower material cost as well as process operating Cost and much lower Capital investment .
  • 9. Machine Design This is a rear combination of , Water Based and Hot melt Coating Machine. The ease of operation of Water Based coating for Casting a film With online Hot melt Adhesive coating
  • 10. Details of Product Construction are as follows PS Adhesive , Hot-Melt Adhesive N Woven Non Woven With a Top coat of PU for smooth finish as well as for excellent water repellence PU Magnified View 17
  • 11. The product ( Non woven Coated Surgical tape ) Is Water Proof. 18
  • 12. The product ( Non woven Coated Surgical tape ) Is Breathable . 19
  • 13. The details of the Process: Coating pass no. 1 : PU water Borne dispersion ( Compounded ) is coating on , Non Woven liner , by Kiss Roll coating method. The Coat Wt. with help of Air Knife. This also helps to create porosity in it. At this stage it is supported by a silicone release liner. The coated NW then enters the drying zone, to flash out water , to obtain a uniform , dry film of PU , on NW + Si liner , laminate . A dry coat weight of approx. 10 gsm is desired and achieved.
  • 14. Coating Machine 21
  • 15. Coating Pass no. 2 : The coated web then enters the second coating station . Here the HM PSA is coated on the Non Woven , by 3 Roller Coating method. The Coating roller is suitably designed for Pattern coating , in order to maintain the porosity in the NW fabric . A coat weight of approx. 18 gsm is desired and achieved. Now the Adhesive coated Jumbo roll is ready for further process of , rewinding and slitting into , Rolls of required length and width.
  • 16. Coating Machine Diagram 23
  • 17. Further Process : Rewinding Machine: 24
  • 18. Rewinding Log rolls of required length , from the Jumbo rolls made as above. 1250 mm 1250 mm ID. 76 mm Jumbo Roll of 1250 mm width X 500 Mtrs length ID. 25 mm Log Roll of 1250 mm width X 10 Mtrs length 25
  • 19. Slicing / Slitting Machine : 25m m 1250 mm ID. 25 mm ID. 25mm Log Roll of 1250 mm width X Finish Roll of 25 mm width X 10 Mtrs length 10 Mtrs length 26
  • 20. Packing Machine : Shrink Wrapping Box Sealing 27
  • 21. Product Cost 28
  • 22. Conclusion The Invented Method of Producing Surgical Tape by using Non Woven with PU coating on top and , HM PSA is very useful. It is light weight , breathable and Water proof. 29
  • 23. Now let us discuss about Part Two
  • 24. A Innovative method to manufacturing Insulation Tape , replacing PVC Film with Cast film using HM PSA
  • 25. Cost Effective Electrical Insulation Tape , replacing PVC Film This is a Innovative method of manufacturing , Insulation tape , by replacing PVC Film with cast film of Radiation Vulcanized Nat rubber latex (RVNRL) , and specially compounded water Borne acrylic PSA , without compromising quality.
  • 26. Advantages     Very light weight Film , of Sp.Gr. below 1.0 as compared to PVC 1.3 , excellent conformability . Higher production speeds due to innovative Coating mc design.  The Product is highly cost efficient , owing to , Lower material cost as well as process operating Cost , and much lesser Capital investment .
  • 27. Details are as follows The Product Construction is given Below.
  • 28. PS Adhesive , either Hot-Melt Or Compounded Water Borne , ( Rubber base / Acrylic ) Adhesive Carrier Carrier Film , prepared by cast method , from compounded RVNRL With a Top coat of PU for smooth finish as well as for excellent water repellence PU Magnified View
  • 29. Method of Manufacture , The Carrier Film The carrier Film , or the Backing material , for the purpose is manufactured by Coating a RVNRL ( Radiation Vulcanized Natural Rubber ) compound , made in house. The Compound recipe is given below.
  • 30. Preparation of WB Dispersion for the additive : The Filler , antioxidant, Flame retardants , are initially, dispersed in water using a suitable dispersing agent and the pH is adjusted to alkaline , using liq. Ammonia solution. The pigment paste is available in water dispersed form.
  • 31. Preparation of Coating Compound: RVNRL is now mixed with pigment paste and dispersion (made as above) , on a slow speed mixer. The pH of the compound is checked and adjusted to 7-8. Now the coating is ready for use. The Coating or Casting is a done on a specially designed coating machine. This machine has number of coating stations , incorporated , to carry out all the coatings in a single pass.
  • 32. The details of the Process: Coating pass no. 1 : On the first Coating station , PU water Borne dispersion ( Compounded ) is coating on , Silicone Release liner , by Kiss Roll coating method. The coated Si liner then enters the drying zone, to flash out the solvent that is water , to obtain a uniform , dry PU film . A dry coat weight of approx. 10 gsm is desired and achieved.
  • 33. Coating pass no. 2 : The coated web then enters the second coating station . Here the RVNRL compound is coated on the same side as PU coated earlier , by Comma Coating method. Here also the coated Si liner then enters the Drying zone , similar to coating Pass no. 1 A dry coat weight of approx. 35 gsm. is desired and achieved.
  • 34. Coating Pass no. 3 : The coated web then enters the Third coating station . Here the HM PS Adhesive is coated on the same side as ( PU + RVNRL) coated earlier , by Roller Coating method. A coat weight of approx. 25 gsm. is desired and achieved.
  • 35. Now in the last phase of this coating operation , the Si Liner is removed and rewound on separate Rewind station no. 2 , and the adhesive coated film is rewound on rewind station no. 1 Now the Adhesive coated Jumbo roll is ready for further process of , rewinding and slitting into , Rolls of required length and width.
  • 36. Coating Machine Diagram
  • 37. Further Process : Rewinding Machine: Rewinding Log rolls of required length , from the Jumbo rolls made as above.
  • 38. The Product Cost Analysis :
  • 39. Conclusion The Invented Method of Producing Electrical Insulation Tape by using RVNRL Film is very Cost Effective. There is a net saving of at least 19 % , which is sizable by any standards.
