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. 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 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.) Applications DMDBH is used for the crosslinking of silicone rubber. Rubber compounds contain DMDBH have excellent scorch safety. Safe processing temperature: 135ípC (rheometer ts2> 20 minutes) Typical crosslink temperature: 175ípC (rheometer t90 about 12 minutes) 18kg/pail

Description of platinum cured silicone rubber Platinum cure silicone rubber is a kind of fda grade silicone , generally named two-components silicone rubber with translucent appearance, part a and part b mixing in 1:1 .It¡¯s suitable for molds making application. Applications of platinum cure silicone rubber Platinum cure silicone rubber mainly used for making concrete stones, wax molds, pu molds, resin molds, gypsum casting, candle molding and chocolate , candy and any other food product molds making Advantage of platinum cure silicone rubber 1)non- shrinkage (less than 0.1% 2)high tensile and tear strength with high copy times 3) exceptional fluidity and good operability (mixing ratio at 1:1 4)high temperature resistant in 250 centigrade Operation instruction of platinum cure silicone rubber Step one: take 100g of part a and 100g of part b and mix in 1:1 and mix the two part evenly. Step two: vacuum pumping Without exception, this step takes less than 10 minutes. Note: the time for vacuum-pumping should be less than 3¡ª5 minutes , otherwise, once the silicone rubber has cross-link reaction during vacuum pumping process, it will not be operated. Step three: pouring the mixture into the frame with original mold slowly . Shelf life for silicon rubber for mold making 810months, when stored in a dry & cool place under the room temperature 25.

The platinum cure silicone rubber can be applied to the mold making industries that used the fiberglass, gypsum, resin, candle, soap, etc. as raw material; or the food mold making industries, tire casting, rapid prototyping and artificial stone crafts. It gets the acknowledgment of the FDA, and its mixing ration is 10:1 or 1:1, which made the operation more easy. Besides that, it also has a lower shrinkage than the mould making silicone. If you have high requirements for shrinkage, then the platinum cure silicone rubber will be your best choice! Operation method of the platinum cure silicone rubber: 1.Mix the platinum cure silicone rubber and the catalyst in a mixing ration of 1:1 and do the process of the vacumn pumping. (If there is no vacumn machine, you can just pour the mixture slowly from the corner so that less bubbles caused.) 2.Put the product which is covered with a layer of release agent in the middle of a squre frame formed of 4 wooden or plastic plates. 3.Pour the mixture into the frame. 4.After 3 to 5 hours, when the silicone cured, get out the original mold, then you get a finished platinum cured silicone mold. And if you are interested in the platinum cure silicone rubber, you can contact Charlie through the information in the company profile.

400 1:1 Most suitable for medium sized product Addition cure silicon rubber for artificial stone products advantages: Flexible, high and low temperature resistance, resistance to ultraviolet radiation, environmental protection, water repellent, good air permeability, good insulation, shrinking smaller Addition cure silicon rubber for artificial stone products points of attention: 1, prone to poisoning, can not mix with condensation, ionic compounds containing n, s-, p, organic matter and of sn, as, hg, ph., easy molding plastic poisoning, resulting in the phenomenon of not curing. 2, comparing with condensation cure silicone, addition cure silicone's adhesive properties to be worse. 3, addition cure silicone affect by temperature greatly when cured under room temperature. 4, addition cure silicone is easy to poisoning, please clean the tools which are used for condensation silicone rubber, so that it can avoid poisoning. Its fobidden to add the pigment or powder to addition cure silicone rubber arbitrarily, its easy to make the catalyst to be poisoning. 5, addition cure silicone rubebr has two-component, the component a and component b, please pay attention to clean the component a containers before using for the component b, and vice versa 6, in order to avoid the hardness change, we should mix the component a and component b according to its mixing ratio strictly, no atter its 1 : 1 or 10 : 1. 25kg/drum or 200kg/drum

Product performance: This kind of product can promote the mixing of different polar rubber, improve its compatibility and process performance. It is suitable for mixing, smelting and calendering operations. It can make the binder bond more closely, so as to improve the effect of mixed coal layer seam, disperse better, mix more evenly, and improve the uniformity of the binder. In addition to increasing adhesive viscosity, it can also improve its fluidity and improve the mechanical properties of vulcanized products. In the formulation of butyl rubber, besides improving the processing performance and promoting the dispersion of fillers, it can keep low modulus and maintain good viscosity after aging, improve the extrusion performance, flexibility resistance and air tightness of the rubber. In addition, it can improve the forming viscosity of synthetic rubber, and has excellent dispersing effect on carbon black and mineral filler, without affecting the low-temperature buckling property.
