THICKENING RETARDANT FOR S(B)MC UPR

DESCRIPTION

Usually, due to the high temperature and high humidity in the summer, the initial
thickening speed is very high, so there is a difficulty in working. However, it
is possible to improve workability by delaying the initial thickening by using
the thickening retardant agent.

SMC/BMC
compound using thickening retardant agent can improve high fluidity and
excellent impregnation due to its initial low viscosity. In addition, after
impregnation, the viscosity increases rapidly, and it increases to the target
viscosity value in a shorter period than before.

PEROXIDE

DESCRIPTION

Trigonox C tert-Butyl peroxybenzoate Initiator for (co)polymerization of ethylene, styrene, acrylonitrile, acrylates and methacrylates.

SPECIFICATIONS CHARACTERISTICS

Active oxygen ≥ 8.07 % Crystallization point 8 °C

Appearance Clear liquid Density, 20°C 1.04 g/cm³

Assay ≥ 98.0 % Viscosity, 20°C 6.5 mPa.s

Color ≤ 100 Pt-Co / APHA

Hydroperoxides as TBHP ≤ 0.10 %

Inorganic + organic hydrolysable chloride ≤ 50 mg/kg

Viscosity, 20°C 6.5 mPa.s

APPLICATIONS

Polymerization of styrene Trigonox C may be used for the (co)polymerization of styrene in the
temperature range of 100- 140°C. In practice, combinations of two or more
peroxides with diverging activities are used to reduce the residual monomer
content in the final polymer and to increase reactor efficiency. In suspension
polymerization processes Trigonox C is often used for reduction of residual
styrene content during the final polymerization stage.

STORAGE

Due to the relatively unstable nature of organic peroxides a loss of quality can be
detected over a period of time. To minimize the loss of quality, Nouryon
recommends a maximum storage temperature (Ts max. ) for each organic peroxide
product.

COLOUR PIGMENT

USE AREAS CAUTION

SMC, BMC Mix enough before use.
Pigmented Resin

STORAGE LIMITATIONS

To ensure maximum stability and maintain optimum resin properties, resins should
be stored in closed containers at temperatures below 23°C and away from heat
ignition sources and sunlight. Resin should be warmed to at least 18°C prior to
use in order to assure proper curing and handling.

Keep containers closed when not in use. Inventory levels should be kept to a reasonable minimum with first-in, first-out stock rotation. Colour pigment has a usage life of 90 day from date of manufacture when stored at 23°C or below in a closed, factory sealed, opaque container, and out of direct sunlight. The usage life is cut in half for every 15°C over 23°C. Product can have even shorter usage life—66% of that for drums.3 months below 25°C, away from direct sun and rain.
