Nanjing SiSiB Silicones Co., Ltd.

SiSiB is worldwide leading manufacturer of organosilanes for over 30 years. SiSiB ureido silanes are bifunctional organosilanes having a reactive organic ureido group and a hydrolyzable inorganic trimethoxysilyl or triethoxysilyl group. The dual nature of its reactivity allows SiSiB ureido silanes to bind chemically to both inorganic materials (e.g. glass, metals, fillers) and organic polymers (e.g. thermosets, thermoplastics, elastomers), functioning as an adhesion promoter and as a surface modifier.

SiSiB PC2510 is a 100% active 3-Ureidopropyltrimethoxysilane. SiSiB® PC2521 is a 50% solution of 3-Ureidopropyltriethoxysilane in methanol.

Ureido-functional silane has better stability than amino silanes in reactive polymer systems, like phenolic, epoxy, urea-melamine or polyurethane. SiSiB Ureido-functional silane does not generate color with time and aging. SiSiB Ureido-functional silane provides nitrogen reactivity without typical aminosilanes strong basic characteristics. SiSiB Ureido-functional silane has good adhesive and sealant adhesion to oil metals.

SiSiB Ureido-functional silane can be used with such polymers as epoxy, phenolic, furan and melamine resins, polyurethanes, PA, PBT, PE, EVA, PP, PVB, PVAC, acrylics and silicones.

SiSiB Ureido-functional silane by SiSiB, a reliable silicone producer, can be used as a size constituent of finish for glass fiber/glass fabric composites.

SiSiB Ureido-functional silane can be used as an additive to phenolic, furan and melamine resins for foundry resins and abrasives.

SiSiB Ureido-functional silane can be used as an additive for silicone sealants and adhesives.

SiSiB Ureido-functional silane can be used as an additive and/or primer for paints and varnishes to improve adhesion to the substrate.
