Active oxygen: 1.7 – 1.9
Form: Liquid
Color: Water-clear to straw-colored
Specific gravity (25°C): 1.08 – 1.12
Viscosity: 25 – 32 mPas
Flash point (SETA C.C.): >149°F/65°C, minimum
SADT: >131°F (55°C)
Soluble in: oxygen-containing organic solvents

Storage Temperature: Maximum 77°F (25°C)/Minimum 32°F

Applications : The combination of NOROX® SHP-40 and cobalt-accelerated resins has been proven to serve as an excellent curing system for unsaturated polyesters at both room temperature and elevated temperatures. The cobalt content (naphthoic acid or octanoic acid in a 1% solution) should range from 0.1% to 1.0%.Compared to MEKP initiators, NOROX® SHP-40 offers the advantages of more complete curing, reduced residual styrene, and stronger parts. Compared to standard AAP, it provides similar gel times and slightly higher peak exothermic heat, but results in better final cure.Typical applications for NOROX® SHP-40 include manufacturing processes such as RTM, fiber winding, centrifugal casting, and continuous lamination.
