水性、環保、全疏型涂料實現可持續應用.pdf

1、Ramadan Abouomar,PhDPakItGreen 1We were working on PFAS alternative at Scops Coating Technologies Then PakItGreen acquired Scops Coating Technologies We developed a Technology that is not only PFAS-Free but also Micro-plastic-Free and used biodegradable technology IntroductionPlastics and microplast

2、ic dilemma PFAS Enigma(very good performance,reasonable price,harmful for environment;Forever chemicals)Paper packaging why recyclability is important?Our New Technology requirements of the coating Performance;water,MVTR,oil and grease Plastics in Packaging(36%of plastics are used in packaging)Examp
