水性、环保、全疏型涂料实现可持续应用.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

3、les applications paper cups problems(20 hrs),Oil test 5 hrs 5-Cobb value of 2 after 30 min 6-Heat-sealing for some formulas 7-Good MVTR(work in progress)Biodegradable coatingOur technology is suitable for many fiber-based substrates including but not limited to:1-Kraft papers 2-Cardboard 3-Cellulose

4、 fibers 4-Pizza boxes SubstratesRational DesignVariety of starting materials to account for:1-film formation 2-Water resistance 3-MVTR 4-OGR 5-Mechanical properties Hardness;toughness 6-Price?!7-Biodegradability Barrier PerformanceMW and MWD Morphology Crosslinking Tg Solubility parameter Polarity A

5、dditives/FillersBiodegradable coating is based on Polyester chemistry with modified structure to improve the OGR/Water performance and to enhance the biodegradability of the coatingExperimental Polymerization&emulsion1-Polymerization 2-Emulsification Chemical characterization4.20.01190.03110.01931pp
