T6-The Use Of Styrene Maleic Anhydride Copolymer Resins As Additives For Both Water Based Pigment Dispersion And Flexographic Ink Transfer, Bill Dougherty, Total Specialties USA
For many years Styrene Maleic Anhydride (SMA) copolymers have been successfully used as both dispersants for water based pigment dispersions and as transfer additives in flexographic printing inks. While studies on the use of SMA dispersants have been well documented, a thorough, quantitative analysis of the use of SMA copolymers as ink transfer aids has not been found. In general, SMA copolymer resins are credited with helping the ink film split off of the rubber blanket and deposit onto the substrate without a lot of misting or printing defects during the flexographic ink printing process. In this study a new SMA copolymer will be introduced which shows excellent performance as a dispersant and an ink transfer aid in both high solids magenta (26-30%) and high solids carbon black (35%) dispersions.
8:45 - 9:30am
T7- Analysis of Primary Aromatic Amines (PAA) in Pigment, Ruth Bauer, BASF
The presence of PAA in inks used for sensitive printing applications continues to receive attention from printers, regulators and CPG’s. Learn about the latest regulatory requirements for these materials and related the state of the art analytical techniques.
9:30 - 9:45am - Break
9:45 - 10:30am
T8-Overview of Development of Low Environmental Impact Ink Component – IsoAlkanes, Frank Bardin, Total Specialties USA
Iiso-alkane fluids may replace traditional hydrocarbons derived from crude oil. They have a similar composition compared to traditional fossil hydrocarbons cuts but are bio-sourced. The industry demand for “mineral oil free” and “petroleum solvent free” as well as changing global regulations are driving the development of market alternatives. The presentation will include:
- Current Market Situation
- Market Impact of Sustainability (regulatory, customer demand, consumer awareness, etc.)
- Technical aspects of the products – What were we trying to achieve?
- Results compared to traditional formulation options
- Testing methodology
- Market Benefits
10:30 - 11:15am
T9- Effect of Surface Tension and Surface Energy of Waterborne Inks on Resolubility, Charlie Hsu, BASF
Surface energy and surface tension played an important role in the resolubility of waterborne inks. As a thin film of ink quickly formed on the surface of anilox, or printing plate when press is not running, the wettability of the dried ink film by the liquid ink itself dictates the speediness of re-dissolving the thin ink film. Waterborne Ink-A made with Polymer-A pertaining a surface tension lower than surface energy of the dry ink film, i.e. ~35 mN/m vs. ~40 mN/m, respectively, exhibited an early colour density recovery of at a resolubility test with 2 minutes’ press shutdown at 20 RH, 68-degree Fahrenheit atmosphere condition. It implied the improvement of interfacial wettability between an ink (liquid form) and dry ink film could advance the resolubility of water borne ink. Atomic force microscopy (AFM) was also utilized for the surface roughness study to investigate its impact on wettability. The contact angle measured for Ink-A was the least affected by the surface roughness and retained the lowest interfacial contact angle between liquid ink and ink film among tested ink samples.
11:15am - 12:00pm
T10 -Overview of the ISO 9001; 14001 and OHSAS 18001 2015 Standard Changes; Creating a true Business Management System, Dave Maternowski, INX
The latest revisions of the ISO 9000 and 14001 series of standards have gone through the biggest change since the year 2000. The upgrades have succeeded in becoming more user-friendly, effective and relevant in today’s manufacturing and service environments. The 2015 revisions align and Quality, Environmental and Safety requirements under one Business Management System. This presentation focuses on the recent changes, systems integration possibilities and the introduction of the latest Safety Standard: OHSAS 18001 – soon to be the official ISO 45000 series of standards.
12:00pm - Group Lunch
