Cyclic Siloxanes & Dual-end Siloxanes - Co-Formula Manufacturer

In addition to silicone fluids, Co-Formula offers a series of cyclic siloxanes including D4, D5, D3F and V4. These siloxanes with a cyclic structure are mainly acting as important intermediates and precursors for the preparation of organic silicone products. Co-Formula main cyclic siloxanes are cyclomethicones, that is a group of methyl siloxanes or cyclic polydimethylsiloxane polymers. Such cyclic siloxanes possess low viscosity, high volatility, excellent spreading properties so they are also used in a wide variety of cosmetic products and maintenance products.

Dual-end Type Siloxanes

Besides silicone fluids and commercial siloxanes for general-purpose applications, Co-Formula has successfully developed a series of specific dual-end type siloxanes. With the efforts of the technical team, several siloxanes dual-terminated with functional groups have been synthesized. Among these dual-end type siloxanes, CFS-267, Tetramethyldisiloxane (abbreviated as TMDSO) is a basic intermediate for the preparation of a wide range of silicone products. It can be used to produce high-performance organosilicon surfactants, liquid silicone rubber, modified silicone oils and organic resin modifiers. CFS-267 can also be used for the preparation of polysiloxanes with functional end groups.

At Co-Formula, you may also find polysiloxanes which are dual end-capped with amino, epoxy, vinyl, methacryloxy and other functional groups. According to different functional group, these polysiloxanes can be used in different application areas. Amino and epoxy dual-end siloxanes are mostly used in textiles, coating and sealants industries. Co-Formula sincerely looks forward to cooperating with international customers to explore the un-known application fields of dual-terminated siloxanes.

Application and Use of Silane Coupling Agent KH-560 (Silane CFS-838)

Industry Application: 1. The silane coupling agent KH-560 can be used in the surface treatment agent on the glass fiber roving. Applications include glass fiber reinforced epoxy composites that improve the physical properties of composites, especially wet strength.  2. KH-560 has the effect of enhancing the physical properties of mineral-filled polymers such as silica-filled epoxy. It is used to improve the dispersibility, compatibility, adhesion and adhesion in the resin phase by surface treatment of inorganic mineral pigments (such as silicon micropowder), flame retardants (such as magnesium hydroxide, etc.) and glass fibers.  3. It is an epoxy-containing coupling agent for caulking and sealant of polysulfide and polyurethane, adhesive for epoxy resin, filled or reinforced thermosetting resin, glass fiber adhesive and It is an inorganic filler or glass reinforced thermoplastic resin. It can improve the adhesion, corrosion resistance, weather resistance, water boiling resista...
