Our technical sales representatives are at hand to assist you in developing bespoke sustainable solutions to formulate heatactivated, contact, reactive and hot melt adhesives in construction, transportation, packaging, furniture and footwear
applications.

Dynasol 

Dynasol supply a number of synthetic polymers for use in the manufacture of rubbers and sealants. Linear, non-crosslinked polymers produce an excellent tack for bonding, coating and sealing applications, whereas crosslinked grades produce adhesive and sealants with a non-stringy, buttery consistency for caulking compounds, mastics and sprayable adhesives.

Emulprene™ SBR is available as crosslinked or non-crosslinked grades in both bale or crumb form

Paracril™ NBR grades include dry, oil extended and crosslinked in bale, crumb or powder form

Imerys

Imerys Carbonates – a selection of coated and uncoated ground calcium carbonates (GCCs) known as PolCarb™, ImerCarb™ and ImerSeal™ can be used as rheology modifiers, tensile strength enhancers, toughening agents, opacifiers and whitening agents.

Imerys Filtration – supply a variety of natural, calcined and flux-calcined diatomaceous earth grades (Celite®, Diafil® and EcoFlat™) which are used as extenders and functional fillers along with their range of both milled and unmilled expanded perlite grades (Europerl® and Harborlite®).

Imerys Kaolin – offer an array of products maintain good barrier effects and rheology control due to their naturally platy structures. These kaolins, calcined kaolins, metakaolins and ball clays known by the brand names Speswhite™, Polwhite™,Polsperse™, Molochite™, Devolite™ and Hexafil™ come in a number of particle sizes to match your application requirements.

Imerys Performance Additives – offer their mica range of extenders and functional fillers in flake and dry ground forms which also provide good barrier effects and rheology control.

Lanxess

Lanxess’s Bayferrox® iron oxide inorganic pigments are available in a variety of colours including black, brown, red and yellow, as well as their Colortherm® chrome oxide greens. Both ranges provide good light fastness when used in adhesives and sealants in both micronized and powder forms.

Shin-Etsu (J Poval and Tylose)

Shin-Etsu’s J-Poval® polyvinyl alcohols (PVOH), ranging from partially to fully hydrolysed grades in granule and powder form, are available to match set requirements in paper adhesives, remoistenable adhesives and plywood adhesives. 

Shin-Etsu’s Tylose® cellulose ethers are used for rheology control, water retention and adhesion promotion, primarily in tile adhesives. Tylovis® starch ethers are also used to reduce the stickiness and skin formation of adhesives and trowelling compounds.

Blackburn

Blackburns Dispelair® foam control agents are used in the preparation and application of a wide variety of adhesives, optimising adhesion properties.

Castor

Castor offer a range of moisture scavengers in both powder and paste form, rheological modifiers, Castor Oils and hydrophobic Castor Polyol D-1150.

Levaco

Levaco provide their Lucrachem® ethoxylated amines and Lucramul® ethoxylated alcohol surfactants which are used as polyurethane water-based rheology modifiers and wetting agents used in adhesives and sealants.

Nouryon

Nouryon’s Levasil® collodial silicas significantly increase the thermal stability and mechanical strength of bonded joints by facilitating the binding of different materials and distributing stress across joints. This nanoparticulate silica solution can help adjust viscosity, as well as shorten the drying time of film-forming organic dispersions.
