Promoting superior performance Radiation curing and polyurethane performance Our polyether polyols, alkoxylates, comprise a range of liquid polyols containing primary and secondary hydroxyls derived from ethylene and propylene oxide respectively. Our alkoxylates are ideal for radiation curing diluents for printing inks and industrial coatings. Another main application is as cross-linkers in polyurethane foams and elastomers to promote superior end-product performance. Ideal additives In addition, our alkoxylates can be used in a wide number of other applications such as in polyol esters for...

Enhancing radiation curing Our unique range of alkoxylated polyols with different hydroxyl functionalities is ideal for radiation curing products. Their use in industrial coatings for wood and plastics, in printing inks and varnishes for graphic arts, and in electronics and adhesives applications promotes superior end-product performance. The improvement of the health and safety profile of acrylate monomers for radiation curing is a major achievement over the past two decades. Our alkoxylates are developed to address this issue and are specially designed to comply with current requirements...

Difunctional polyols – safety & performance 38 We now offer Polyol R2490 as an alternative to typical di unctional polyols hexane diol (HD) and tripropylene f glycol commonly used as starters for acrylate diluents. The acrylate of R2490 is a difunctional monomer that provides a number of advantages over hexane diol-based acrylates. As a non-irritant product it allows Xi-free labeling of formulations and is much less air inhibiting during free radical polymerization thanks to abstractable alpha-hydrogens. Much lower surface tension for better wetting of low surface energy substrates and...

Trifunctional polyols – optimal performance Wetting and adhesion control Wetting and adhesion control 38.0 The surface tension and contact angle on PE of the acrylates of trifunctional polyols R3530 and R3600 Coating performance control Coating performance control 9 The hardness and flexibility of the acrylates of trifunctional polyols TMP, R3600, 3380 and 3165 Optimized performance and efficiency Contact angle on PE, degrees Our wide range of trifunctional polyols, alkoxylates of Tri ethylolpropane (TMP), are tailored to meet your demands m for surface tension, reactivity, solubility and...

The reactive diluent obtained through acrylation of tetrafunctional Polyol R4631 is a non-irritant but with higher viscosity than difunctional or trifunctional acrylate. Nevertheless, it is very effective in increasing curing speed, chemical resistance, and abrasion resistance while decreasing the amount of unreacted monomer. Tetrafunctional polyols – optimal curing speed 100 80 60 40 20 0 Reference formulation Polyol R4631 acrylate is the product of choice for: Gloss 20° retention after 200 scrub scotch-brite test showing improved scratch resistance with the acrylates of polyol R4631 Wood...

Fine-tuning with polyols Enhancing polyurethane elastomers & foams Polyol 3990 – liquid TMP for ease of handling To facilitate the handling of TMP by our customers and improve the hardness/flexibility of elastomers, we have developed a TMP grade with a low degree of alkoxylation – Polyol 3390, a liquid product with primary alcohol groups that eliminates the need for heating. Polyol 3610 & Polyol 4800 – tailored toughness 4360 Polyol 3610 and 4800 are two grades suitable for elastomers that provide ways of controlling the cross-link density and maintaining the resilience and toughness of...

New opportunities Polyol R6405 – improving stability Polyol R4630 – the first of a new generation We focus on developing products that contain low amounts of undesired glycols. Polyol R4630 is the first of a new generation of alkoxylates and is designed to support the penetration of radiation curing coatings and printing inks in applications where residual low molecular weight acrylates is a key issue. Low impurity levels enable use of UV acrylates in applications where the lowest skin irritation and low migration are of highest importance. R4630 has an even lower level of impurity than our...

Alkoxylate portfolio product names For example, Polyol 4640 is a tetrafunctional alkoxylated polyol with an OH value of 640. This product is used widely as a cross-linker in polyurethane formulations. Many of these products have a low water and/or ash content making them especially suitable for polyurethanes. Our alkoxylated polyols cover a functionality of 2, 3, 4 and 6, and with OH values of 150–1000 mg KOH/g suitable for specific application demands. They are logically named to help you quickly identify and select those of interest. Each name consists of Polyol XY, where X =...
