Applications:

• Curing agents for unsaturated polyester resins
• Temperature range: 80-150°C
• Dose level: 1-31 TP3T as supply
• Shelf life" (gelation time of the resin + peroxide) of several days or weeks at room temperature.
• Sensitive to certain fillers, pigments and additives
• Inhibitor BC 500 with 0.1-0.31 TP3T significantly extends shelf life

Curing Characteristics:

• In the range of 70-80°C ("starting" temperature), the curing is slow, unless there is an exothermic reaction (e.g. in a mold with insulation). A really short cure time of 1-3 minutes can only be achieved above 120°C.
• Therefore, the optimum temperature range for thermo-compression molding is 120-150°C.

Treatment:

• It is mainly used for hot press molding of sheet molding composites (SMC) or block molding composites (BMC), wet press molding (e.g. profile, paper layer pressing), impregnation (winding).

Storage:

• Observe recommended storage temperature ranges to maintain quality and availability, for safety reasons
• Comply with the safety recommendations of local regulations and codes, as well as the requirements of the relevant authorities and the requirements of your insurance provider.

Packaging: TMCH-HA-M1 is packaged in a standard 20kg package.
