Unsaturated polyester resin applications

Order number of typical products



Thermal stability Quino Power improves thermal stability in production and kneading processes.
Storage Quino Power improves stability during transportation and storage.
Molding Quino Power does not retard curing on molding.

Stability and curing property are thus attained simultaneously.

Excellent thermal stability and stability during storage

Test conditions:
Monomer: Distilled styrene
Atmosphere: Nitrogen
  • BHT:2,6-Di-t-butyl-4-hydroxytoluene
  • MEHQ:4-Methoxyphenol
  • BQ:Benzoquinone
  • HQ:Hydroquinone
  • TBC:4-tert-Butylcatechol

Excellent molding characteristics (supporting efficient molding cycle without retarding curing)

Unlike other inhibitors, Quino Power does not retard curing time.

Even if added at high concentrations to enhance stability, Quino Power does not retard curing.

Test conditions:
Curing characteristics at 80℃
(JIS(Exothermic method A),2008
Resin; Unsaturated polyester (Styrene-based,commercial product)

Quino Power QS-10 has actually been applied on a commercial basis in the US and Europe.

Quino Power QS-20 has still enhanced thermal stability and storage stability.
