Toluhydroquinone(THQ)

This product is an efficient unsaturated resin polymerization inhibitor. Generally, a resin addition of 0.02% can achieve good polymerization inhibition effect in production and storage, and the stability of preventing resin hardening after polymerization exceeds six months;
Methylhydroquinone is characterized by good solubility, low addition amount, and good thermal stability, with little effect on resin lipidation time. It is an updated product of hydroquinone and does not pollute its own product. It is not affected by temperature and environment;
Used as a stabilizer and antioxidant for unsaturated resins, as well as for non edible oils, fats, fatty acid esters, flaxseed oil, etc. It can also be used as an antioxidant for pigments, dyes, and pharmaceutical intermediates.
