Premium diol for high-performance polyester, unsaturated polyester and polyurethane resins
Premium diol for high-performance polyester, unsaturated polyester and polyurethane resins
Synthomer’s SYNOXOLTM BEPD (butyl ethyl propanediol) is a high performance aliphatic diol, with primary OH groups, for the synthesis of saturated and unsaturated polyesters. It is also used in the formulation of polyester polyols, or as a chain extender as part of polyurethane resins.
Polyester Coil Coatings | Polyester Powder Coatings | UPR Gelcoats & Composites | Polyurethane Applications |
Increased hardness | Improved bloom resistance down to 140-160°C cure temp | Reduced viscosity | Higher hydrolysis resistance |
Lower VOC & Styrene content | Improved abrasion resistance | ||
Improved flexibility | Reduced gel time | Lower water absorption | Improved water resistance |
Higher UV resistance | Higher UV resistance | Higher flexural strength | Higher transparency |
Increased spreading rate (m²/Lt) | Increased reactivity | Lower shrinkage upon cure | Lower MFFT |
Improved cost/m² | Reduced energy cost | Improved UV resistance | Higher gloss |
Powder coatings
Prevents production stoppages and extra labour costs associated with blooming of polyester resins during cure, at formulation loadings small enough not to require new polymer regulatory notification. Delivers up to three times productivity increase for powder coatings application lines that utilise pyrimid cured polyester resins, meeting superdurable performance as per GSB and Qualicoat Class 2.
Coil coatings
Minimises mechanical damage risks during production and installation of pre-painted metals that comply with RUV4 outdoor durability, as per EN 13523-10 and EN 10169. Helps to formulate high solids, low VOC polyester resins and coatings for outdoor applications, and delivers polyester resins that lead to coating formulations with increased spreading rate (m2/Lt), which translate to cheaper cost/m2 coil coating price.
Gelcoats
Reduces occupational hazard risks associated with handling styrene, by delivering unsaturated polyester formulations that don’t require high levels of styrene co-polymer utilisation. Minimises mechanical damage risk of the gelcoat layer during handling and de-moulding of high-performance composites for demanding applications; and improves the aesthetics and long term durability of composites by incorporation into unsaturated polyester resins used in gelcoat applications.
Polyurethanes
Helps to formulate polyester polyol based adhesive resins with high tack and instant adhesion properties for outdoor applications; delivers polyols and polyurethane resins that give hydrophobicity, flexibility and abrasion and stain resistance to textile garments; optimises rigidity of TPUs whilst also ensuring high transparency and gloss where needed; and contributes to chemical resistance, high flow, high gloss, flexibility, abrasion and chip resistance of water-based polyurethane dispersions used in wood and automotive coatings, delivering environmentally friendly high performance coatings.
