Products in Structural Components: Silicones

SILRES® BS 1705 is a high-quality water-thinnable emulsion that is solvent-free and based on a mixture of silane and siloxane compounds. It is specifically designed to act as a specialty water repellent for impregnating cement-based products, including fiber cement. By impregnating cement-based materials, such as fiber cement, with SILRES® BS 1705, their water repellency is significantly enhanced, providing long-lasting protection against water absorption and related problems. This makes SILRES® BS 1705 an excellent choice for improving the durability and performance of cement-based products in various applications.

SILRES® BS 1703 SQ (000010587) is specifically designed for the in-plant water-repellent treatment of fiber-reinforced cement products, including fiber-cement boards. Its main purpose is to greatly reduce the capillary water absorption of these construction materials once they have set and reached equilibrium moisture. The use of SILRES® BS 1703 SQ provides enhanced protection against water damage, contributing to the longevity and quality of fiber-reinforced cement products.

ELASTOSIL® M 4635 A/B is a room-temperature-curing silicone rubber (RTV-2) that is pourable and utilizes addition-curing. It consists of two components and vulcanizes at room temperature. The main application of ELASTOSIL® M 4635 A/B is in making molds for concrete casting. This grade is also compliant with FDA and BfR regulations for food contact applications.

CENUSIL® M 830 A/B is a room-temperature curing silicone rubber (RTV-2) that is pourable and cures at ambient temperature. This addition-curing silicone rubber is specifically designed for making molds used in concrete casting. Moreover, CENUSIL® M 830 A/B is compliant with food contact regulations, including FDA and BfR standards.

ELASTOSIL® M 4630 A/B is a pourable, addition-curing, two-component silicone rubber that vulcanizes at room temperature. It offers a fast and non-shrink cure at room temperature, which can be significantly accelerated with the application of heat. The main application of ELASTOSIL® M 4630 A/B is in making molds for concrete casting. Additionally, this grade is compliant with FDA regulations for food contact applications.

SILRES® BS 1703 SQ (000096394) is also primarily intended for in-plant water-repellent treatment of fiber-reinforced cement products, such as fiber-cement boards. It exhibits a higher flash point and increased storage stability compared to SILRES® BS 1703. While it may have a slightly opalescent appearance with a slight yellowish discoloration, it does not affect the excellent performance of the product.

Polsil® GUM 100/60 is general purpose heat cured elastomer widely used for molding and extrusion in various industries.

Lamitex® G-7 SI GC 21 glass/silicone laminated sheets are primarily used for mechanical, electrical and electronic applications where high mechanical strengths are required at temperatures up to 220°C. G-7 exhibits extremely good dielectric loss properties under dry conditions and good electrical properties under humid conditions.

PREPREG system SG (silicone resin) are based on a silicone resin. Its Processing is hot pressing or prepreg winding.

Polsil® GUM 100/50 is general purpose heat cured elastomer widely used for molding and extrusion in various industries.

Sil-Flex HT RTV-7565 (Neutral) is a one component, low modulus, neutral cure high temperature silicone sealant and adhesive. This product offers non-corrosive adhesion to many sensitive metals such as copper, foil, brass, zinc and bronze. This product is specifically formulated to offer all weather performance to meet today's Green Building Standards.

StarPCS™ SBMC-843 is a discontinuous carbon fiber reinforced molding compound containing carbon fiber, a Starfire proprietary polysiloxane resin, and refractory particulate. SBMC-843 contains a Polyramic® thermosetting resin which cures at temperatures between 200-310°C, and functions as a high temperature carbon fiber reinforced structure with a silicon oxycarbide ceramic matrix. Compression mold curing produces a green fiber reinforced polymer matrix composite (PMC) material. Further processing to 850°C minimum in inert environment results in an amorphous silicon oxycarbide ceramic matrix composite (CMC) to be used with different infiltration polymers or materials. Ideal infiltration polymers include Polyramic® SPR-212, SPR-212 based slurries (SL-227, SL-480), and other Starfire® polysiloxane products.

Polsil® GUM 100/70 is general purpose heat cured elastomer widely used for molding and extrusion in various industries.

Polsil® GUM 100/40 is general purpose heat cured elastomer widely used for molding and extrusion in various industries.

StarPCS™ SBMC-601 is a discontinuous carbon fiber reinforced molding compound containing carbon fiber, a vinyl substituted polysiloxane resin, and refractory particulate. SBMC-601 cures at temperatures between 180-250o C and functions as a high temperature carbon fiber reinforced structure with a silicon oxycarbide ceramic. Curing produces a green fiber reinforced composite material. Further processing to 850o C (minimum) in inert gas results in an amorphous silicon oxycarbide matrix ceramic composite that can be used as a pre-form for use with different infiltration polymers or materials. Ideal infiltration polymers include Polyramic® SPR-688 or SPR-212 based slurries (SL-227, SL-480), and other Starfire® Systems polysiloxane products.
