As a dielectric fluid. What are emulsions? • Silicone emulsions are whitish stable mixtures of silicone and water. The advantages of using them instead of fluids are: • For easy processing by using a water-based silicone. • The stability of their emulsions and dilution. • They are available in a wide range of pH’s and of silicone active substance. • MEM-0036, MEM-0346, MEM-0347G. 3 ANTIFOAMS What are antifoams? • Antifoams improve production processes, from dyeing textiles and fermentation, to the manufacturing and use of detergents. • The silicone antifoam compounds are composed of silicone and silica fluids. • Silicone antifoams emulsions are stable mixtures of antifoams compunds and water: - Silicone antifoam compound (dispersed phase). - Water (continuous phase). - One of more surfactants. • Powdered silicone antifoams are composed of - Stabilizing additives. antifoam compounds and a solid agent. Main usage for silicone antifoams Reduces the formation of foam in the production process or when using: • Detergents for clothes. • Industrial paper mills and paper processing. • Food industry processes, with FDA regulation. • Beer fermentation and distillery processing, juices and general drinks. • Dyeing processes in the textile industry. • Pesticide processes • Water filling and mixing of liquids. 4 RESINS What are resins? • Silicone resins, when used as coatings offer an extraordinary and lasting resistance at extreme external external temperatures up to 760ºC, to corrosion, humidity, to electrical shocks and to aggressive surroundings. Silicone resins are complex tridimensional structures made of highly branched siloxane polymers. They require very high temperatures of curing. They are compatible with most organic resins, easily pigmented and exist in solid form and liquid form, pure or dilated in organic solvents. Main usage for silicone resins • As binding agents for paints used in high temperatures such as exhaust pipes, boilers, pots, heaters and chimneys. • In protective and antifouling paints for ships. • As varnishes for coating glass cloth, for impregnating and protecting electric coils and resistors. • As non-stick industrial coatings. • Coatings to protect transformers and solenoids from dampness.

Silanes help to improve: • Mechanical resistance, acting as crosslinkers. • Electrical properties. • Resistance to humidity in polymers. • Repelling of water. • Adhesion, they are used as adherence promoters. • Compatibility. • Dispersion of pigments, minerals, and charges. Silanes and some derivative products with siloxane mixture or siliconates have a significant purpose for use in construction, serving as water re- pellents for building materials, as protectors from environmental conditions, to reduce staining, or to improve the fragility of some materials.

Used when a more specific formula is required (over 500 references) for large parts and medium-small series. Bases are only available for formulation or prepared compounds for direct use. • LSR liquid rubber (fluid). A pumpable fluid. For small and/or complex parts to be molded and for long series.

From the manufacturing materials used for silicone molds, it is possible to create hard but flexible molds for reproducing intricate detail and creating high quality replicas again and again. These can be used with the originals made from stone, glass, wood, metal, wax, ceramics, plaster and clay and are compatible with a wide range of molding materials. Main usage for molding products: • To reproduce figures, jewellery, candles… • For prototype molds, furniture, industrial tools… • Rubber pads for transfer printing. Each moldmaking product is made up of two components: a base of liquid silicone rubber and a catalyst or cure agent. There are two basic types of curing, condensation curing or addition curing. For each type of curing, we offer several products in a range of viscosities and variable cure times.
