Product Description::

• CUROX? M-370 is a colorless to slightly yellowish liquid mixture consisting of methyl ethyl ketone peroxide and acetyl acetone peroxide blended through dimethyl phthalate.
• The main application is the curing of unsaturated polyester resins with cobalt accelerators at 20 - 40 °C for molding polyester parts at ambient temperatures.

Technical data::

• Appearance: slightly yellowish clear liquid.
• Inhibitor: Dimethyl phthalate.
• Active Oxygen (AO): 7.71 TP3T w/w minimum.
• Density (20°C): approx. 1.13 g/cm3.
• Viscosity (20°C): approx. 28 mPa-s.
• Flash point: > 65°C.
• Insoluble with water, but soluble with o-phenyl ester and unsaturated polyester resin.
• Critical temperature (SADT): approx. 60°C.
• Recommended storage temperature: 0 - 25°C.
• Storage stability from date of delivery: 3 months.
• Standard package: 25kg HDPE drum.

appliance::

• A special cold curing agent for unsaturated polyester resin curing that can be used with cobalt accelerators at ambient temperatures.
• Small amounts of inhibitors can be used to prolong the gel time, but large doses of inhibitors are usually not suitable because they decrease the reactivity of the peroxide.
• Gel time is similar to CUROX? M-303, but cures significantly faster.
• Not for use in heat curing systems and not for vinyl.

Treatment::

• The products are suitable for a variety of processes such as hand lamination, spray molding, RTM, continuous lamination, centrifugal casting, fiber winding and curing of molded parts in polyester concrete.

decomposition product::

• Decomposition products that may be detected include acetone, methyl ethyl ketone, fatty acids and acetylacetone.

stockpile::

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