United Initiators NOROX®PD-40 FRED 3,5-dimethyl-1,2-dioxolane-3,5-diol 13784-51-5

Product Description::

• NOROX® PD-40 FRED is a red liquid containing acetylacetone peroxide with reduced sensitization by means of an acetone diol coolant.
• The peroxide is suitable for use as a free radical initiator for curing unsaturated polyester resins.
• Primary application: In combination with a cobalt catalyst for curing thin-walled molded parts at room temperature.

Technical data::

• Appearance: red liquid
• Sensitive degraders: Glycol, Vinyl ketone glycol
• Activated Oxygen (AO): approx. 4.11 TP3T w/w
• Density (20°C): approx. 1.1 g/cm3
• Viscosity (20°C): approx. 37 mPa-s
• Can be mixed with alcohols and phthalates
• SADT: approx. 60°C
• Recommended storage temperature: 10°C to 25°C
• Storage stability after delivery date: 6 months

appliance::

• Used to cure unsaturated polyester resins in combination with cobalt catalysts at room temperature.
• Storage time (resin + peroxide gel time) is usually only a few hours, depending on temperature and resin type.
• The conventional working time (gel time for resin + peroxide + catalyst) is relatively short, but can be extended by the addition of an inhibitor (e.g. TC-510 inhibitor).
• The initiator introduces intense heat into the curing system, which reduces demolding time.
• Even at temperatures below 20°C, curing remains relatively fast, especially in combination with Accelerator CA-12.
• Some fillers, pigments or stabilizers may interfere with or completely prevent curing.
• This product is not applicable to vinyl.

Treatment::

• Can be used in a variety of processes including hand lamination, spray lamination, vacuum and injection molding (RTM), wet compression molding, centrifugal casting (pipes), and continuous impregnation (corrugated sheets).

save::

• Avoid heat, light, humidity and protect the product from impurities.
• Stay within the safe temperature range.
