BHT-INHIBITED MONOMERS
A variety of product applications and foreign regulations have restricted the use of Hydroquinone (HQ) and 4-Methoxyphenol (MeHQ) as polymerization inhibitors. In response, Esstech can offer the following products with non-detectable or limited levels of HQ and MeHQ:
The following monomers can be supplied with “non-detectable” levels of HQ and MeHQ as determined by GPC Analysis
- X-943-7466 Triethyleneglycol Dimethacrylate, 100 ppm BHT
- X-945-7466 Tetraethyleneglycol Dimethacrylate, 100 ppm BHT
- X-844-7469 2-Methoxyethoxyethyl methacrylate, 500 ppm BHT
- X-887-7466 1, 6-Hexandiol Dimethacrylate, 100 ppm BHT
- X-947-7466 Trimethylolpropane Trimethacrylate, 100 ppm BHT
- X-850-1066 Urethane Dimethacrylate, 150 ppm BHT
- X-851-1066 Urethane Dimethacrylate IPDI, 500 ppm BHT
The following monomers can be synthesized with low or non-detectable levels of HQ and MeHQ but, the BHT analog of each is currently not part of Esstech’s commercial product offering.
- X-726-0000 Exothane 9
- X-930-0000 Exothane 10
- X-894-0000 Exothane 32
- X-846-0000 HEMA Maleate
- X-821-2000 Methacroyloxyethyl Phthalate (MEP, PAMM)
- X-753-0000 HEMA Succinate
- X-865-0000 Pyromellitic Dimethacrylate (PMDM)
