New Shell GTL Waxes of SX90 and SX110 in Hotmelt Adhesives Applications

by Dr Kay Kian Hee, Product Innovation & Technical Manager, Shell MDS (Malaysia) Sdn. Bhd.

Presentation Abstract

Recent innovations by Shell have led to the introduction of two new GTL wax products to their product portfolio. Shell GTL Sarawax SX90 is a unique narrow cut GTL hard wax, and Shell GTL Sarawax SX110 is the highest melting GTL hard wax available. This study investigates the performance of these novel waxes in Hot Melt Adhesive (HMA) formulations with a metallocene-type base polymer. The results show clear advantages for both waxes compared to currently available options, offering greater control over open/setting times and excellent heat resistance. The cohesive and adhesive strength of HMA formulations can be fine-tuned through the high crystallinity of these waxes, combined with their different molecular weight distributions. Due to its narrow cut origin, SX90 provides competitive low-temperature stability and high peel adhesion strength, while boasting a comparatively low melting temperature. SX110 easily outperforms all other waxes with respect to high-temperature stability, without compromising HMA formulation viscosity. Therefore, the expanded selection of Sarawax SX90, SX105 and SX110 offers versatile solutions for effective and reliable control over HMA processing and properties.

Hybrid Polymer Sealants – Minerals for Performance Enhancement

by Ms Shamila Grigorieff, R&D Scientist - Adhesives & Sealants, Imerys Performance Minerals

Presentation Abstract

Silane-modified polymers are designed to combine the strength of polyurethanes with the weathering resistance of silicones. In addition to their high performance properties, these hybrid polymers are achieving popularity due to their solvent-free and isocyanate-free nature. Sealants based on hybrid polymers also provide good over paintability, stain resistance, and excellent primerless adhesion to a wide range of substrates. In silane-modified sealants the mineral component can represent over 60 wt. % of a commercial formulation. The choice of mineral will therefore have an impact on the processing and ultimate performance of the sealant. This presentation evaluates the performance of minerals in such sealants. Specifically, the effects of coated calcium carbonates (ground & precipitated) on their stability, rheology and mechanical properties are reported. The potential impacts on the process route are discussed in parallel. The results demonstrate that the selection and control of the physical properties of the mineral are critical in improving the sealant production process and its physical properties.

Unique Radiation-Curable Styrenic Block Copolymer for High Performance Adhesives

by Ms Martine Dupont, Sr Staff Scientist - Adhesive Applications, Kraton Polymers Belgium (Subsidiary of Kraton Corporation)

Presentation Abstract

Radiation curing technology is a fast growing area, which offers opportunities to achieve properties that would not be conceivable with traditional hot-melt adhesive systems. High temperature and solvent resistance can be achieved with hot-melt systems, while keeping a good process-ability at economically attractive rates. The UV curing technology can be applied to different hot-melt systems, either rubber or acrylic based. It however requires development of dedicated products to ensure proper reactivity, good adhesion properties and low and stable hot-melt viscosities. This paper will focus on Kraton’s new styrenic block copolymer specially designed for radiation curable pressure sensitive adhesives and its applications. The Kraton radiation curable polymer can be formulated in a similar way as any conventional hot-melt adhesive. It is highly thermally stable at normal process temperatures and shows excellent reactivity towards radiation curing. It can be used in combination with sustainable technologies, such as rosin ester and terpene based tackifier chemistries.   It also exhibits very interesting performance compared to competitive systems: it shows very good adhesion on non-polar substrates and its hydrophobic character provides it an excellent water resistance.

Advanced Dissolver-Technology for the Efficient Production of Adhesives

by Mr Dominik Kastl, Team Leader of Mixing Technology Product Management, NETZSCH Feinmahltechnik GmbH

Presentation Abstract

For the automated production of higher viscosity products in large batches, it is essential to have a good homogenization of the whole product in the tank as well as to disperse and dissolve dry ingredients homogeneously. Also the temperature should stay in the allowed range. Commonly used combinations of butterfly mixing tools together with tooth discs often cannot work as good for large batches as they do for small and medium batches. The reason for this is the arrangement and design of the tools. The innovative design of the NETZSCH Intensive Mixer PMD-VC overcomes the disadvantages of traditional mixers with a separation of tasks and has some further very helpful features to produce batch by batch quickly and to the desired quality! The presentation will explain this production technology and point out how producers of Adhesives can benefit from it. Complementary to this technology, also a short overview about our machines for higher and lower viscosity is included to cover the whole range of product characteristics.

New Label-Free Light and Heat Stabiliser Solution Delivering Superior Performance for Silyl-Modified Polymer (SMP) Sealants

by Mr Jean-Yves Desrats, Global Technical Segment Manager, Performance Additives Coatings, Clariant International Ltd and Mr Christopher Dobbins, Application Manager, Adhesives & Sealants, Omya International AG

Presentation Abstract

Modified silane sealants and adhesives are the fastest growing technology since they combine the advantages of polyurethanes and silicones while cancelling out their disadvantages. Current light and heat stabilization solutions are under the microscope from the regulatory authorities, resulting in reclassification due to increased hazards. In addition, these standard solutions tend to cause yellowing and do not provide sufficient service life for the sealants. To address these challenges, Clariant and Omya have developed the latest generation of light and heat stabilizer solution to outperform today’s industry standards. Our presentation will address the three main areas of improvement, specifically for SMP sealants, and introduce new strategies to avoid labelling, reduce yellowing and improve durability.

A Novel Way of Looking at Polyamide Waxes: Sustainable, High Performance, Versatile Rheology Modifiers for Reactive Systems

by Ms Orlane Bouzard, Technical Manager, Adhesives & Sealants Additives, Arkema

Presentation Abstract

To optimize rheological profiles of reactive adhesives and sealants, polyamide rheology modifiers are a sustainable market reference for combining ease of application with structure development, compared to other technologies such as Fumed Silica, PCC… They have been established as a key additive in Silylated Terminated Polymer (STP) systems with successful extensive use for many years. As applications using STP-based products become ever more demanding, rheology modifiers - which are key ingredients - are evolving to help adhesives & sealants manufacturers to meet these challenges. For example, the market is moving increasingly towards higher load-bearing capacity in STP adhesives driving the need for high tack systems. Additionally, ease of handling and sustainably sourced raw materials are becoming the norm. Such benefits can also be achieved in other technologies including Epoxies, 2K PU and Acrylates, where polyamides can withstand more traditional rheology modifiers’ performance and bring additional features. After introducing the Polyamide Rheology Modifiers technology, their benefits in each relevant system will be described. This presentation will showcase the innovation in STP systems, adapting to the aforementioned challenges: shortening cycle times, enhancing tack. It will then detail how such additives can be interesting in other reactive systems by demonstrating rheological performance using different characterization methods.

Rheological Characterization of Water-Based Tile Adhesives

by Dr Catherine Corfias-Zuccalli, Technical Manager, Adhesives & Sealants Additives, COATEX (Arkema Group)

Presentation Abstract

How to ensure that a tile adhesive spreads easily and holds up when positioning the tiles? What does it take for a correct adhesive application? The answer lies in optimizing rheological properties of systems to achieve the thickness and workability together with control of sag, hold up and creep of the wet adhesive. Control of its application is essential to ensure its final mechanical and adhesion properties. The applicability of aqueous adhesives via a notched spatula is very dependent on the ability of the adhesive to flow under stress. Thus, the rheological approach is relevant to physically describe the flow mode of these soft solid viscoelastic materials that need to be applied with a high, regular and homogeneous thickness on different substrates. The objective is to identify the rheological parameters that best describe the applicability of these thick aqueous adhesives. We will characterize the resistance to crushing when placing the tiles and its capacity to repositioning if necessary, the initial grab and sliding resistance, comparing various acrylic thickeners. These characterizations will be carried out in formulations comprising the essential ingredients to target the mechanical resistance of these thick adhesives, aiming at achieving correlations between viscoelastic behavior and application properties.
