Though crude oil is rightly the ultimate source of many chemicals the adhesive industry uses, renewable alternatives can offer an alternative to aid economic and supply sustainability. To this end,...

While thermoset epoxy adhesives are commercially successful their shrinkage on curing, toughness and reworkability could be improved. Hyperbranched polymers, large molecules with many functional... (1 Member Reaction)

This article will focus on the use of styrene block copolymers in solvent borne sealant systems. It explores the value propositions provided by solvent borne SBC based sealants to the end-user and... (2 Member Reactions)

Marcus Navin-Jones of Keller & Heckman have assessed the likely impact of the new Biocidal Products Regulation on the key issue of treated articles. The current Biocidal Products Directive (BPD) does...

Sometimes, innovations emerge that force existing guidelines for formulating adhesives to be rethought. The principles, abilities and limitations of using styrene block copolymers (SBCs) in hot melt... (2 Member Reactions)

Microencapsulation can be an important instrument in the adhesive or sealant formulator’s toolbox. This versatile technology makes it possible to combine materials that are otherwise incompatible or... (1 Member Reaction)

Alternatives to conventional solvents and other VOCs that are employed in waterborne adhesive formulations are discussed in this article. The primary focus is on coalescing agents or co-solvents... (2 Member Reactions)

Using just one basic backbone polymer chemistry, polyurethane adhesives can serve a wide range of applications, from food packaging to structural panels. The major challenge for adhesive formulators... (1 Member Reaction)

This article provides an overview of renewable additive materials that are being used and developed for use in biobased adhesives and sealants. The drivers and barriers are also reviewed in an effort...

Until recently the lack of control in emulsion polymerisations has meant that most acrylic PSA formulation knowledge came from solution polymerisation. But recent improvements have meant better... (3 Member Reactions)

This article will first review the advantages of acrylic / polyurethane hybrid waterborne sealant formulations, and the routes to producing a polyurethane / acrylic base polymer system. The article... (1 Member Reaction)

Glass transition temperature and storage modulus are two essential properties in controlling a pressure sensitive adhesive's performance. Elastomers often don't initially have properties that fit in... (1 Member Reaction)

This article will first examine the reasons that external plasticizer modification may not be necessary with polyurethane adhesives and sealants. It will then review the possible value that can be... (3 Member Reactions)

To date there are no encapsulants that adequately protect UV LEDs without breaking down. Silicones are popular as LED encapsulants, but conventional addition cure formulations form organic crosslinks...

This article will focus on the moisture induced degradation of the bulk adhesive when the degradation is permanent. This is a mechanism known as hydrolysis. It is dependent on the chemical nature of...

The conflict between needs that must be met when designing a hot melt adhesive can lead to a compromise that falls short of meeting any of them comprehensively. For example,...

This article reviews that status of POSS for use in adhesive systems, primarily epoxy and polyurethane, although POSS has found advantages in other systems as well. The unique physical properties of...

The diisocyanates used to produce polyurethane adhesives can be toxic, and so it's important to reduce the amount that users are exposed to. Polyurethane prepolymers can help achieve this, but usually...

The motor car has been with us for more than 120 years and today it is hard to imagine life without the motor car. It has transformed our way of life, our landscape, and our outlook. Worldwide it has...

How poly(vinyl acetate ethylene) (VAE) emulsions are made has a critical role to play in the properties and cost of the adhesives that they're used to make. While batch reactors are more flexible,...
