SYNOXOLTM BEPD in Coil Coatings

Florida weathering

SYNOXOLTM BEPD offers new possibilities whencreating highly flexible and durable coil coatings.

Gloss retention after 2 years exposure

We recommend exchanging 1,6-Hexanediol for
SYNOXOLTM BEPD in order to benefit from:10080• Improved solvent compatibility
60%• Improved weathering• Increased resin Tg with no viscosity increase• Improved hardness

4020• Improved stain resistance

SYNOXOLTM BEPD in Can Coatings
In view of societal concerns over epoxyphenolic systems in the can coating market,
SYNOXOLTM BEPD is an ideal candidate
monomer for alternative polyester systems.
• Improves resistance to hydrolysis andincreases stability during the sterilization
process• Increases compatibility with solvents andleads to lower VOC of the coating• FDA approved, with EU approval underway

SYNOXOLTM BEPD in Powder Coatings
In Powder Coatings, the key performance
attributes of SYNOXOLTM BEPD are:

• Improved hydrophobicity• Improved resistance to blooming• Increased reactivity whilst maintainingviscosity

SYNOXOLTM BEPD in Polyurethane
Systems
Used in both polyester polyols and as a chain
extender in a wide variety of application areas
such as:• Coatings for wood, leather, textiles• High performance adhesives• TPU• Foam for shoe soles
In PU systems SYNOXOLTM BEPD offers:• Improved hydrolysis resistance• Reduced crystallinity thus increasedtransparency• Improved abrasion resistance• Good film formation at low MFFT withincreased gloss

Leading in emulsions andspeciality polymers
Synthomer is one of the world’s leading
suppliers of emulsion and speciality polymers
supporting leadership positions in manymarketsegments
includingcoatings,
construction, technical textiles, adhesives,
paper and synthetic latex gloves. Thecompany has its Head Office in London (UK)and provides customer focused services fromoperational centers in Harlow (UK), Marl(Germany), Kuala Lumpur (Malaysia),
Shanghai (China) and Dubai (UAE). In June
2016 we have acquired the Monomers,
Dispersions and Powders business (MDP)from Hexion with dedicated production, sales
and customer service facilities in North
America, Europe and South East Asia.

In March 2017, we acquired the coalescing
agents and Butyl Ethyl Propanediol (BEPD)
business from Perstorp Oxo Belgium AB. The
newly acquired businesses significantly improve
our footprint to a number of speciality markets
which we will continue to serve through a strong
network of local technical service and sales
branches, supported by regional application
development and production in our key markets.
We deliver the right formula, globally,individually.
