DMDBH curing agent
Apperance: past
Assay: 45%
CAS: 78-63-7
Molecular weight :290.4
Active oxygen content peroxide :11.02%
Cas no. :78-63-7; 68083-18-1
Einecs/wlincs no. :201-128-1
Tsca status : listed on inventory
DMDBH is a bifunctional peroxide which is used for the crosslinking of silicone rubber
Appearance : Transparent evenly paste
Assay : 43.0-45.0%
Density, 20ípC : 0.870 g/cm3
Flashpoint : 56ípC
Freezing point : 6ípC
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, we recommend a maximum storage temperature (TS max.) for each organic peroxide product.
For DMDBH TS max.= 30 ípC
When stored under the recommended storage conditions, DMDBH will remain within the specifications for peroxide of at least 6 months after delivery.
Thermal stability
Organic peroxide are thermally unstable substances, which may undergo self-accelerating decomposition. The lowest temperature at which self-accelerating decomposition of a substance in the original packaging may occur is the Self-Accelerating Decomposition Temperature (SADT). The SADT is determined on the basis of the Heat Accumulation Storage Test.

The lowest temperature at which self-accelerating decomposition of a substance in the original packaging may occur is the Self-Accelerating Decomposition Temperature (SADT). The SADT is determined on the basis of the Heat Acumulation Storage Test.
For DMDBH SADT: 80ípC
Packing and For DMDBH, the standard packaging is 18kg/drum.
Transport
Safety and handling: Keep containers tightly closed. Store and handle DMDBH in a dry well-ventilated place away from sources of heat or ignition and direct sunlight. Never weigh out in the storage room.
Void contact with reducing agent (e.g.amines), acids, alkalines and heavy mental compounds (e.g. accelerators, driers and metal soaps.)

25kg net kraft paper bag with PE bag inside or as clients' options.
Properties: It is yellow to brown schistose or granular solid, synthesized by formaldehyde, modifying agent, active agent and parasubstituted alkylphenols which have different number of carbon atom in the alkyl groups.
Applications:The super tackifying resin has the characteristics of long-term effective, nice moisture stability and high viscosity-promoting ability. It's viscosity-promoting ability is similar to para-tertbutylphenolaceylene resin and superior to para-tert-butylphenol(or para-tert-octylphenol) formaldehyde resin.
This product should be added under the temperature higher than it's softening point in the early period of mixing, to ensure the resinf+s homodisperse and to get the best viscosity-promoting effectiveness. It can save the use level of processing oil to a certain degree. The recommended dosage is 2-5 phr.
Storage: Kept in dry and ventilating place, protected from heat and fire, the storage life is 18 months. The products that exceed storage life and qualified can be used.
Package: Packed in knitted bags lined with a layer of kcraft paper bag and a layer of plastic bag. The netweight is 25kg per bag.
