DMS -C16 by Gelest (Mitsubishi Chemical) acts as surfactant and processing aid for dispersion of particles in silicone formulations. In DMS -C16 the term carbinol refers to a hydroxyl group bound to carbon (C-OH) and is frequently used in silicone chemistry to differentiate them from hydroxyl groups bound to silicon (Si-OH) which is referred to as silanols. It contains primary hydroxyl groups which are linked to the siloxane backbone by non-hydrolyzeable transition groups. It may be reacted into polyurethanes, epoxies, polyesters and phenolic. This carbinol (hydroxyl) terminated siloxane with caprolactone transition blocks offer a highly polar component which enables compatibility in a variety of thermoplastic resins. Used in encapsulant applications. DMS -A21 by Gelest (Mitsubishi Chemical) is an aminopropyl terminated polydimethylsiloxane. This aminoalkylfunctional silicone has a broad array of applications as a result of its chemical reactivity, ability to form hydrogen bonds and chelating ability particularly in the case of diamines. DMS -A21 additional reactivity can be built into aminoalkyl groups in the form of alkoxy groups. It reacts to form a variety of polymers including polyimides and polyurethanes. The block polymers based on it are becoming increasingly important in microelectronic (passivation layer) and electrical (low-smoke generation insulation) applications. It is also employed in specialty lubricant, surfactant and encapsulant applications. DMS -E09 by Gelest (Mitsubishi Chemical) is a polydimethylsiloxane, epoxypropoxypropyl terminated. It is a difunctional and multifunctional epoxy silicone includes lower molecular weight siloxane with discrete structures and higher molecular weight siloxane with either pendant or terminal epoxy functionalization. Its compatibility with conventional epoxies varies. In simple unfilled systems, total solubility is required but for filled systems, it is often desirable to consider systems that are miscible but have only limited solubility since micro phase separation can allow a mechanism for stress-relief. It selectively imparts a wide range of properties, associated with silicones i.e. low-stress, low temperature properties, dielectric properties as well as release depending on its specific structures and formulations. DMS -E09 is used in encapsulant applications. DMS -H41 by Gelest (Mitsubishi Chemical) is hydride terminated polydimethylsiloxane. This polymer undergoes three main classes of reactivity: hydrosilylation, dehydrogenative coupling and hydride transfer. The silanol terminated polydimethylsiloxanes react with hydride functional siloxanes to produce foamed silicone materials. In addition to the formal chemistry described above, the presence of oxygen and moisture also influences cross-link density and foam structure. It is chain extender for vinyl-addition silicones, enabling low viscosity, high elongation formulations. DMS -H41 is used in encapsulant applications. DMS -A211 by Gelest (Mitsubishi Chemical) is N-ethylaminoisobutyl terminated polydimethylsiloxane. This aminoalkylfunctional silicone has a broad array of applications as a result of its chemical reactivity, ability to form hydrogen bonds and chelating ability particularly in the case of diamines. DMS -A211 additional reactivity can be built into aminoalkyl groups in the form of alkoxy groups. Used in encapsulant applications. DMS -V35R by Gelest (Mitsubishi Chemical) is vinyl terminated polydimethylsiloxane. This polymer is employed in addition cure (platinum cure) which provides an extremely flexible basis for formulating silicone elastomers. The vinylmethylsiloxane copolymers are mostly employed in peroxide activated cure systems which involve peroxide induced free radical coupling between vinyl and methyl groups. The formulation of addition cure silicones must address the strength, hardness, consistency, temperature of cure, work time (speed of cure), shelf life and compounding. This reduced volatility grade does not form any by product which allows fabrication of parts with good dimensional stability. Its relatively low viscosity is employed as grafting additives to EPDM elastomers in the wire and cable industry to improve electrical properties. DMS -V35R is also used in sealants and encapsulants applications. DMS -A35 by Gelest (Mitsubishi Chemical) is an aminopropyl terminated polydimethylsiloxane. This aminoalkylfunctional silicone has a broad array of applications as a result of its chemical reactivity, ability to form hydrogen bonds and chelating ability particularly in the case of diamines. DMS -A35 additional reactivity can be built into aminoalkyl groups in the form of alkoxy groups. It reacts to form a variety of polymers including polyimides and polyurethanes. The block polymers based on it are becoming increasingly important in microelectronic (passivation layer) and electrical (low-smoke generation insulation) applications. It is also employed in specialty lubricants, surfactant and encapsulant applications. DMS -A11 by Gelest (Mitsubishi Chemical) is an aminopropyl terminated polydimethylsiloxane. This aminoalkylfunctional silicone has a broad array of applications as a result of its chemical reactivity, ability to form hydrogen bonds and chelating ability particularly in the case of diamines. DMS -A11 additional reactivity can be built into aminoalkyl groups in the form of alkoxy groups. It reacts to form a variety of polymers including polyimides and polyurethanes. The block polymers based on it are becoming increasingly important in microelectronic (passivation layer) and electrical (low-smoke generation insulation) applications. It is also employed in specialty lubricant, surfactant and encapsulant applications. DMS -A214 by Gelest (Mitsubishi Chemical) is N-ethylaminoisobutyl terminated polydimethylsiloxane. This aminoalkylfunctional silicone has a broad array of applications as a result of its chemical reactivity, ability to form hydrogen bonds and chelating ability particularly in the case of diamines. DMS -A214 additional reactivity can be built into aminoalkyl groups in the form of alkoxy groups. Used in encapsulant applications. DMS -H31 by Gelest (Mitsubishi Chemical) is Poly (dimethylsiloxane) hydride terminated. This polymer undergoes three main classes of reactivity: hydrosilylation, dehydrogenative coupling and hydride transfer. The silanol terminated polydimethylsiloxanes react with hydride functional siloxanes to produce foamed silicone materials. In addition to the formal chemistry described above, the presence of oxygen and moisture also influences cross-link density and foam structure.
