  15. 15. By Shrikant Athavale Prathith Consultants Pune India 1522-08-2013 PromisetoattendyourTechnicalneeds A Presentation On Water Repellent Coating ( water borne ) , for Packaging Applications www.psadhesive.com
  16. 16. 1622-08-2013 PromisetoattendyourTechnicalneeds It all started about two and half years ago. The Govt. of India and Govt. of Maharashtra , imposed a Ban on Gutka packaging Pouches , made out of Plastics Film and aluminum foil. The Govt. , notified that , the pouches as mentioned above should be plastic polymer free. www.psadhesive.com
  17. 17. 1722-08-2013 PromisetoattendyourTechnicalneeds I was applying my mind to develop a alternative packaging material . This prompted me to try paper with a suitable coating on it which might be an alternative. Suddenly , I realized that , I had a lot of information stored in my PC , on water repellent / proof coatings. www.psadhesive.com
  18. 18. 1822-08-2013 PromisetoattendyourTechnicalneeds I got in touch with some of these Manufacturers based in USA , and Germany. There response was very quick to my sample requests and I eventually received couple of samples from well renowned companies like Michel man, Nu Coat , Aqua Base Technologies and BASF www.psadhesive.com
  19. 19. 1922-08-2013 PromisetoattendyourTechnicalneeds In order to carry out the coating trials , I then thought of setting up a small Laboratory , in my home itself. The trials were very successful and , I could see a great promise in the emerging Alternative Technology . www.psadhesive.com
  20. 20. 2022-08-2013 PromisetoattendyourTechnicalneeds This was the stage to consider the cost of the product. I realized that the cost was very much on higher side , and although the product quality and performance was good enough , the buyer would be really concerned about the cost. This prompted me to re think on the whole issue. www.psadhesive.com
  21. 21. 2122-08-2013 PromisetoattendyourTechnicalneeds One day , I was on my morning walk as usual . It had just rained . While crossing through a lavish green Garden , I could see Water droplets on some of the leaves , shining like Pearl. I suddenly realized , it was very much similar to the water droplet formed on the coated paper in my Lab. www.psadhesive.com
  22. 22. 2222-08-2013 PromisetoattendyourTechnicalneeds www.psadhesive.com
  23. 23. 2322-08-2013 PromisetoattendyourTechnicalneeds That morning , was like a catalyst in my R&D activity. The nature , prompted me to think on the alternative Natural Resources , available in abundance. www.psadhesive.com
  24. 24. 2422-08-2013 PromisetoattendyourTechnicalneeds And The result of this was , That I could concentrate myself on the possible usage of naturally occurring Waxes , such as Bee’s Wax, Carnauba wax, soya wax etc. The next challenge was , how to emulsify these waxes in Water and how to bind them together . Subsequently , I could develop methods to emulsify them , in my Laboratory , and use of Natural Rubber Latex , and or Styrene Butadiene Latex , as a binder. www.psadhesive.com
  25. 25. 2522-08-2013 PromisetoattendyourTechnicalneeds The results were very promising. I worked on these formulations for nearly six months , and then I could freeze the formulations. The next stage was to protect my R&D work . Hence , I approached a leading consultant for Patent right Protection. That is how , the Manufacturing / compounding Process was Patented on 09/09/2011 www.psadhesive.com
  26. 26. 2622-08-2013 PromisetoattendyourTechnicalneeds Here , I must mention a fact . I consider myself just as a compounder. The Doctor / or specialist Doctor is nobody else but the great Nature . Nature has a solution for possibly any task and the same are always available in abundance. The job of a human being is just to Identify the same and make use of it , in the most practical manner. This is what , I have done precisely. The nature has graced us with lot many resources and in return , we have to give it back. I hope this is the real definition of Bio Degradability. www.psadhesive.com
  27. 27. 2722-08-2013 PromisetoattendyourTechnicalneeds Patent Receipt www.psadhesive.com

  33. 33. 3322-08-2013 Coating Methods www.psadhesive.com
  34. 34. 3422-08-2013 Pulp Blending The process of paper recycling involves mixing Scrap paper with water and chemicals to break it down. It is then chopped and heated, to break it down into strands of cellulose, which is called pulp, or slurry. It is strained through screens, which remove any glue or plastic that may still be in the mixture then cleaned, de- inked, bleached, and mixed with water. www.psadhesive.com
  35. 35. 3522-08-2013 Pulp Blending It is at this stage , mix our Water Repellent coating , approximately 5-10% of the pulp quantity . Then it can be made into new paper. This paper will exhibit excellent Water Repellent Properties. www.psadhesive.com
  36. 36. 3622-08-2013 www.psadhesive.com
  37. 37. 3722-08-2013 Recycling of paper There are three categories of paper that can be used as feed stocks for making recycled paper.  Mill broke  Pre-consumer waste and Post-consumer waste www.psadhesive.com
  38. 38. 3822-08-2013 Paper Recycling Saves 1. Energy It takes approximately 64% less energy to make paper from recycled materials ( used paper ) than from virgin fibre ( trees). Recycling one ton of paper saves the equivalent of 70 gallons of gasoline or 3 barrels of oil. 2. Water It takes 61 % less water to make paper from 100% recycled materials www.psadhesive.com
  39. 39. 3922-08-2013 Paper Recycling Saves 3. Land Every ton of paper recycled saves 100 cubic feet of landfill space 4. Air Making recycled paper results in 70% fewer air pollution than making paper from virgin wood. 5. Natural Resources ( Trees ) for every ton of paper recycled , approximately 17 trees are saved www.psadhesive.com
  40. 40. 4022-08-2013 Water Repellent Chemistry Water repellent or water proofing agents are generally of two forms Elastomeric coatings that adhere to the substrate and cure to form a flexible and protective layer Water repellent chemicals that penetrate deeply into the substrate and they bond with it. www.psadhesive.com
  41. 41. 4122-08-2013 The mechanism of Water Repellency Repelle nt Permea ble The water Repellent coating is formulated in such a way that the surface tension of the same is suitably adjusted for easy wet out on the surface ( paper ) to be coated. This is why the paper exhibits superior water repellency. at the same time it does not penetrate into the pores , and hence it is breathable. Trapped Water vapour’s can easily slip through , however the water molecules are too large to penetrate. www.psadhesive.com
  42. 42. 4222-08-2013 The mechanism of Water Repellency The water repellent additive can be blended with the paper pulp and it wet out paper molecules more effectively and bonds them together hence the moulded pulp is 100% water proof , with very negligible water vapour transfer www.psadhesive.com
  43. 43. 4322-08-2013 Advantages 1. This is ideal Replacement for Plastic coated paper 2. The Coated paper is Recyclable 3. Excellent Coat ability on paper , 4. Good Gloss 5. Very Good Water Resistance 6. High Coating speeds 7. Lower Coating weight ( approx. 5-6 gm dry per sq. Mtr. ) 8. Cost effective by at least 15-20% www.psadhesive.com
  44. 44. 4422-08-2013 Paper Water Repellency & Water Beading with This additive Consumer Grade Premium Grade Initial After 1 hour After 2 hours www.psadhesive.com
  45. 45. 4522-08-2013 The Water Repellent additive imparts greater water repellency and water beading We recommend a dosage of 5-7 % of Pulp for Consumer grade and 7-12% for Premium grade www.psadhesive.com
  46. 46. 4622-08-2013 Technical Information Our Water Repellent Additive is a low VOC, hydrophobic , non silicone water borne emulsion specifically designed to impart water repellency and beading on paper.
