CUROX ? CM-75R A liquid mixture of methyl ethyl ketone peroxide and tert-butyl peroxide. This is a red liquid made primarily from a mixture of peroxides based on methyl ethyl ketone peroxide and tert-butyl peroxide, essentially desensitized by phthalate plasticizers. The mixture is used as a curing agent (source of free radicals) for unsaturated polyester resins, especially vinyl ester resins. The main areas of application include vacuum impregnation and plastic bagging technology, as well as curing of hand/spray reinforced parts at room temperature with cobalt or cobalt/amine accelerators, mainly for thicker laminated materials. Technical data include: Appearance: red liquid Active oxygen content: approx. 8.

DESCRIPTION: CUROX? CM-75 is a peroxide mixture on the basis of methyl ethyl ketone peroxide and tert-butyl peroxide, with the addition of a phthalate plasticizer, yellow in color and fluid. It is used primarily as a curing agent for unsaturated polyester resins, and is particularly suitable for vinyl resins. It is mainly used in vacuum infiltration/plastic bagging technology and with cobalt or cobalt/amine accelerators for curing hand/spray reinforced parts at room temperature, mainly for thicker laminated products. Technical Data: Appearance: Yellow Liquid Reactive Oxygen Content: approx. 8.81 TP6T (mass fraction) Hydrogen Peroxide Content: approx. 0.71 TP6T (mass fraction) Water Content: approx. 1.21 TP6T (mass fraction)

NOROX?SG-10 FRED Chemical name: Methyl ethyl ketone peroxide CAS No.: 1338-23-4

Product Description: NOROX? SG-10 is a ketoacetophenone peroxide for curing unsaturated polyester resins with cobalt catalysts at ambient temperature, which provides high levels of reactive oxygen and hydrogen peroxide, resulting in faster gels and cures than NOROX? KP-9 and NOROX? KP-100.NOROX? SG-10 provides consistent room temperature performance in a variety of systems, including polyester resins and coatings. It is a reliable, high-purity product for a variety of applications such as making button boards, continuous lamination, centrifugal casting and polyester concrete. Due to its high hydrogen peroxide content, NOROX? SG-10 is not recommended for use in

Product Description: NOROX? 771 is a mixture of methyl ethyl ketone peroxide and tert-butyl hydroperoxide containing a coagulant. It is a liquid polymerization initiator for the ambient curing of special unsaturated polyester and vinyl ester resins. It has the following advantages and properties: Lower peak maximum exotherm Excellent 24 hour cure time Longer gel time Reduced foaming in vinyl ester resins Low shrinkage Technical Data: Reactive Oxygen Content: Not to Exceed 9.01 TP6T Form: Liquid Color: Colorless and Transparent Specific Gravity at 25°C: 1.2 Flash Point (SETA C.C.): Minimum 150°F/66°C Solubility: Oxygenated Organic Soluble

CUROX?A-300 Chemical name: 3,5-dimethyl-1,2-dioxolane-3,5-diol CAS No.: 13784-51-5

Product Description: CUROX? A-300 R is a red liquid containing an acetone peroxide, which is permeated with diacetone alcohol. This ketone peroxide is suitable as a free radical initiator for curing unsaturated polyester resins. The main area of application is the curing of thin-walled molded parts at room temperature in combination with cobalt accelerators. Characteristics: Due to the bright red color of the peroxide, its uniform distribution in the resin system can be easily checked. The red color disappears during the curing process. Technical Data: Appearance: Red Liquid Desensitizer: Glycol, Diacetone Alcohol Active Oxygen (AO): approx. 4.11 TP6T (mass %) Density (20°C):

DESCRIPTION: CUROX? A-390 is an almost colorless liquid consisting of a peroxide based on acetylacetone and tert.Butylperoxybenzoate, desensitized by diketone alcohol. It is a free radical initiator for the curing of unsaturated polyester resins and is mainly used for the curing of fiber-wound parts with cobalt accelerators at room and elevated temperatures. Technical Data: Appearance: Almost colorless liquid Reactive Oxygen Content: approx. 4.51 TP6T (mass fraction) Desensitizer: Diacetone Alcohol Density (20°C): approx. 1.07 g/cm3 Viscosity (20°C): approx. 34 mPa-s Solubility: miscible with alcohols and phthalates Critical Temperature (SAD)

DESCRIPTION: NOROX WPC-100 is a liquid based on a peroxide formulation of acetylacetone peroxide and tert-butyl peroxybenzoate.
