Short Courses

Wednesday, September 4, 2024

Coatings Trends & Technologies Summit is expanding its offerings with four short courses.
These short courses will offer an extensive day of interactive learning.

Full Agenda
Short Course Agenda

Participants will learn:

• Definition, Surfactant Types and Structures
• The Influence of Atomic Bonds and Molecular Attractive Forces on Interfaces
• Surface Activity including Surface Tension/Pressure/Transport and Micelle Formation
• Foam Stabilization and De-Stabilization
• The Role of Surfactants in the Dispersion Process
• Surface Tension Measuring Methods
• Introduction/Definition of Rheology
• Essential Elements of Rheology
• Stress and Deformation Forces
• Viscosity and Flow Profiles
• Rheological Agent Types
• Rheological Agent Chemistry
• Measuring Methods
• Review

This short course initially reviews the various types and chemical structures of commercially available surfactants. We then dive into an understanding of the role of inter-atomic and inter-molecular attractive forces as it relates to surface tension. The course progresses to a better understanding of various surface activities including surface area, surface tension, surface pressure, wetting, surface transport, and micelle formation. We will explore the world of foam with respect to how surface-active agents stabilize and de-stabilize bubbles at the surface or as entrained air. Finally, a review of surfactants as an aid to the dispersion process and the measurements of surface tension in both static and dynamic conditions.

The second part reviews the basic principles of rheology, including its definition and its influencers - chemical structure, morphology, and environmental conditions. The impact by various deformation forces, including compression, tension, torque, and, particularly, shear will be reviewed to demonstrate the resulting flow profiles of viscosity as a function of shear and time. The chemistry and ancestry of current rheological agents will help clarify the appropriate selection of products for various formulation types including waterborne, solventborne, aliphatic, aromatic, and polar systems.

While targeted to formulating chemists, this course is also well suited for marketing, sales, and production personnel. Managers and supervisors would also benefit by having a better understanding, and appreciation, of the important role surfactants and rheology play to the production, storage, transport, and application of quality paints and coatings.

Participants will learn:

• Where powder coatings are used and their benefits vs. liquid coating technologies
• The components of a powder coating formulation, including binder selection
• How powder coatings are manufactured and applied
• Test methods for evaluation of coating performance

This abbreviated version of the popular “PC Kitchen” course will introduce new formulators, chemists, and customer-facing personnel to the basics of powder coating. The presenters will discuss how powder coatings are formulated (resin/crosslinker selection, pigments, and additives), important processing details (premixing, extrusion, grinding, and particle classification), and laboratory test methods that are commonly used to evaluate powder coatings for performance. Participants will also be given a brief overview of where powder coatings are used, as well as their benefits and drawbacks compared to liquid coating technologies.

Participants will learn:

• Selection of rheological additives based on research in real-life formulations
• Differences between particular types of rheological additives
• Conducting formulating work and rheological measurements in the lab
• Using several rheological additives in formulations to ensure maximum workability of the paints
• The influence of rheological additives on other coating parameters (e.g. scrubbability, water sensitivity) and correct use before being introduced into the formulation

A practical guide to rheological additives in latex paints, including cellulose ethers, clays, HEUR, and HASE/ASE thickeners. Step-by-step discussion of the selection of rheological additives based on research procedures, taking into account obtaining initial viscosity, and stabilizing viscosity over time, including storage stability, tintability as tint viscosity stability, as well as viscosity in the entire area of shear forces (Brookfield, Stormer, ICI-CAP), with attention to secondary rheological properties such as brush/roller drag, spattering, sagging, leveling.

Participants will learn:

• How to select the appropriate resin for different applications
• Different curing mechanisms
• Identification and troubleshooting of common coatings defects

This course will cover coatings resins; resin chemistries and selection; different curing mechanisms [including oxidative cure, two-component, energy cure (UV and baking) and coalescence]; and common coatings defects (what they are, what causes them and how to cure them). The course is intended for beginner to intermediate chemists.
