• Maximum transportation temperature: 25°C
• Maximum storage temperature: 20°C
• Period of validity after delivery: 6 months

Applications.

• Mainly used for the curing of unsaturated polyester resins in combination with the use of more thermally stable peroxides.
• Usage ratio: 1-2% as supplied.
• "Shelf life" (gel time of resin + peroxide) is a few weeks at room temperature, depending on resin type, filler and pigment.
• The "service life" (gel time of resin + peroxide + accelerator) lasts several days in combination with more thermally stable peroxides (peroesters), depending on temperature and dosage.
• Shelf life and service life can be significantly extended by the addition of the inhibitor BC-500 with 0.1-0.31 TP3T.

Curing Properties.

• In the 50°C (122°F) range, the cure rate is not high unless there is an exothermic reaction (e.g., in an insulated mold).
• Good curing properties can only be obtained by adding peroxides with higher thermal stability.

Curing Process.

• Mainly used for pultrusion, hot press molding, wet press molding, CIPP (cured-in-place pipe), etc.

Packaging.

• NOROX? 600-CL2 comes standard in four 11 lb. (bagged) cardboard packages.
