Language: English
ID: KH0016
Time Length: ~ 90 Min.
Description: Wood and other lignocellulosic composites are growing in use and the adhesives used in these composites plays a major part in how these composites perform in terms of mechanical and wet exposure properties. The largest wood composites markets are for panel products like Oriented Strand Board (OSB), Plywood, Particleboard (PB) and Medium and High-Density fiberboards (MDF and HDF). Another growing area that requires high performance adhesives is Cross Laminated Timber (CLT) which is a large-scale, prefabricated, solid engineered wood panel used in building construction. This webinar will discuss the complex nature of wood adhesion and explore the use of isocyanate and polyurethane adhesives as high performance adhesives for wood composites. The mechanism of how isocyanate and polyurethane adhesives work will be discussed along with important factors to consider when using these adhesives to make wood and lignocellulosic composites. The presentation topics include: An introduction to adhesive considerations, The unique nature of wood as a bonding surface, The chemistry of isocyanates and polyurethanes, Mechanism of isocyanate and polyurethane adhesion, Summary of important concepts, Questions and discussionss

Organofunctional Silane Adhesion Promoters (Part 1): Fundamentals
Language: English
ID: KH0032
Time Length: ~60 Min
Description: Adhesion promoters, or coupling agents, act as molecular bridges at the interface between a polymer and a substrate to enhance adhesion between the two materials. The type of adhesion promoters considered in this webinar are difunctional or multifunctional reactive silanes that contain both organofunctional and hydrolyzable groups. These organosilanes are applied as primers to the substrate or are added to the adhesive or sealant formulation in order to achieve self-priming adhesion characteristics. The art and technology of adhesion promotion resides in the chemical design of the adhesion promoter molecule based on its affinity for the substrate and for the applied adhesive or sealant. When formulated into an adhesive or sealant, multiple (and competing) reaction and diffusion mechanisms have a major influence on the effectiveness of the adhesion promoter. Ideally, the interfacial bridge formed by the adhesion promoter will improve the initial joint strength and prevent delamination of the adhesive or sealant from the substrate, even when exposed to water or other weathering influences. This Part 1 webinar will cover What are Coupling Agents?, Why use them as Adhesion Promoters?, Types of Organofunctional Silane Coupling Agents, Basic Silane Coupling Chemistry, Adhesion Promoting Mechanisms, Primer – the 'Go-Between' – Different Concepts

Moisture Cured, One Component, Reactive Polyurethane Adhesives
Language: English
ID: KH0046
Time Length: ~90 Min
Description: Moisture cured, one component, reactive polyurethane (PU) adhesives are formulated using an isocyanate and amorphous and crystalline polyols of varying composition which are reacted to form a polyurethane prepolymers. These prepolymers can be liquid or they can be solid at room temperature. If they are solid at room temperature, they are considered reactive hot melt adhesives. All reactive PU adhesives contain residual isocyanate functionality that is reactive with moisture that comes from the atmosphere and/or the surface to be bonded. Reactive PU adhesives contain catalysts to promote the moisture cure and also contain other additives to control rheology, open time and strength of the resulting polyurethane polymer. The choice of polyols, based on performance requirements is an important factor in formulating any polyurethane system. Designing reactive, one component adhesives is no different. Understanding how isocyanate and polyol structure affect reactivity and the physical properties of the formulated adhesive is an important aspect of formulation, which this webinar is intended to provide. The presentation includes: An introduction to adhesive considerations, Comparison of PUR adhesive systems, the chemistry of isocyanates and polyols, Formulating from a Structure / Property perspective, Summary of important concepts

Controlling Adhesion in 3D Printing: A Material Science Perspective
Language: English
ID: KH0130
Time Length: ~60 Min
Description: 3D Printing offers new opportunities to fabricate prototypes, models, and is expanding into the consumer market. 3D printing, also known as additive manufacturing, offers a method to produce incredibly complex components directly from a computer-aided design (CAD) model. Unfortunately, the layered nature of the fabrication process results in anisotropic properties and performance that are dominated by interfaces that are formed during production. The expansion of 3D printing will require the development of materials, methods, and techniques to strengthen these interfaces in a highly controlled manner. This webinar will discuss methods to realize this improvement of interfaces, discuss potential uses and markets for 3D printing and the potential role of interfacial modifiers and adhesives in this endeavor. The presentation content includes: # To learn the benefits and potential limitations of 3D printing; # Provide insight into the importance of interfaces and potential role of Adhesives in 3D Printing; # Develop understanding of Opportunities to use 3D Printing in manufacturing

Applications of FTIR in Polymer Process Development
Language: English
ID: KH0136
Time Length: ~60 Min
Description: FTIR spectroscopy is a powerful technique for studying the effects of polymer formulation and process factors on surface chemistry, component compatibility, and morphology; all of which relate to end-use performance characteristics like adhesion and mechanical properties. Of the many techniques available, surface attenuated total reflectance spectroscopy (SATR-FTIR) is arguably one of the most versatile FTIR methods, enabling the study of neat liquids, solutions, dispersions, solid films, solid powders, adhesives, adherends, and countless other multi-component systems. Aside from being fast, SATR can be applied in problem-solving situations pertaining to cure reactions (liquid and dispersion states), surface compositions & adhesion, process history & surface heterogeneity (e.g., extruded films), material structure, and product/process control. This seminar, although focused on SATR, will be the first in a series pertaining to applications of spectroscopic methods in product and process development. Those attending can expect to learn how SATR-FTIR can be applied to their own real-world product development & problem-solving situations. The webinar presentation includes: • Overview of FTIR spectroscopy & methods; • Description of the SATR technique; • Example Applications - Adhesion, Surface migration, Extruded film heterogeneity, Polymerization reactions, Material structure & composition
