HENKEL
Hot- and Cold-Sealable Coatings for PackagingApplications
The recently expanded RE range, which is “designed for recycling,”includes both hot- and cold-sealable coatings for paper. According to Henkel, the products are certified as paper-recycling compatible and allow a new range of packaging designs.
Sustainability is one of the most important factors when it comes to packaging of goods across the board. The first step when designing packaging in a recycling-friendly way that is also compatible with a circular economy starts by ensuring adhesives and coatings can accommodate alternative materials like paper for various food and non-food applications.
“The main purpose of packaging is protection—and this is still what underpins our strategy,” said Alexander Bockisch, Henkel’s head of global market strategy for Flexible Packaging. “The scope also includes developing adhesives and coatings that help improve recyclability and allow new packaging designs. Our two latest developments are certified recyclable and can replace plastic packaging. Both sealable coatings enable full recyclability of paper packaging in food and nonfood applications.”
DELO
Die-Attach Adhesive
A new die-attach adhesive reportedly offers high strength after aging. According to tests performed in conjunction with machine integrator ASM Assembly Systems, DELO MONOPOX EG2596 can be dispensed more precisely than its predecessor. This new fluorescent adhesive is suitable for long-term use in semiconductor and surface mount technology applications.
DELO MONOPOX EG2596 can be used on printed circuit boards to fix components and act as electrical insulation. It is temperature resistant and offers good dispensing properties, meeting the increasing miniaturization requirements in today’s electronics.
The company reports that this heat-curing, one-component epoxy resin adhesive exhibits a 150% higher strength after seven days of storage at 85% relative air humidity and a temperature of 85°C. DELO MONOPOX EG2596 maintains strong adhesion even after typical aging tests (e.g., the MSL1 test), in accordance with JEDEC standard. When using 1x 1 mm² silicon dies, the test revealed adhesion values of 47 N on FR4 substrate and 62 N on gold.
TOYOCHEM
High-Solids Polyurethane Pressure-Sensitive Adhesives
A new Cyabine™ series of polyurethane pressure-sensitive adhesives (PSAs) reportedly features an ultra-high solids content of 99% or more. According to the company, the new adhesive composition achieves the same performance levels as conventional solvent-based PSAs while reducing solvent and volatile content to minimal levels. The adhesives are suitable for use in a wide range of industrial applications, such as protective films.
To meet the demand for lower VOC-emitting products, Toyochem reports that it has been gradually building on its lineup of high-solids adhesive compositions with high levels of non-volatile content. This new PSA product was the outcome of new technological developments in synthesis and crosslinking methods developed by Toyochem. These advances allowed the company to engineer a new high-solids system that contributes to reduced CO₂ gases during coating and drying processes for a safer, more environmentally sound work environment.
HUNTSMAN
High-Performance Adhesive Range
The ARALDITE® 2000 Adhesive Core Range is designed to help businesses across many industries maximize productivity by covering up to 80% of all bonding needs, from assembling high-performance products to making repairs in tough conditions. The ARALDITE Adhesive Core Range comprises nine high-performance adhesives that the company reports can simplify product selection, reduce stock keeping unit (SKU) inventory, and minimize worker training.
The ARALDITE Adhesive Core Range consists of three technologies: epoxy, acrylic, and polyurethane. The adhesive products are reportedly resistant to impact, high temperatures, water, and chemicals while offering a variety of colors, open times, viscosities, and appearances.
Huntsman reports that these products enable greater innovation, performance, and sustainability, with well-proven applications across bus and truck, rail, wind, marine, and general industry. Meeting stringent industry safety standards, the range includes products with KIWA approval; Lloyd’s Register approval; and conformity to HL3 requirements, ClassR1 and R7, of the Railway European Fire Protection Standard EN 45545-2.
SONGWON
Flame-Retardant Dispersion
SONGFLAME® WB 201 solvent-free, aqueous, flame-retardant dispersion is designed especially for the coatings, adhesives, sealants, and elastomers (CASE) market and is also suitable for textile applications requiring flame-retardant properties. The benefits of the new product reportedly include easy handling for customers working with waterborne systems, as well as low viscosity and a high active content.
In keeping with its commitment to help improve sustainability throughout the value chain, SONGWON reports that it has built up the new flame-retardant synergist portfolio with a view to promoting the growth of halogen-free solutions. SONGFLAME WB 201 is the latest addition to SONGWON’s water-based portfolio. Developed to meet the increased demand for environmentally acceptable additives, the new ranges combine the efficiency of conventional products with the benefits of water miscibility, low-to-zero VOC generation, and easy dosing and handling.
