White powder form superfine silica. It is a wax treated, medium particle sized precipitated silica. Very low viscosity impact, high surface smoothners and sedimentation behavior.
Crosile® 69s is a mixture of Crosile® 69s silane coupling agent and precipitated silica with the same function as liquid Crosile® 69 but easier to operate. It can improve the physical and mechanical properties of rubber and greatly strengthen tensile strenth, antitearing strenth, abrasion resistance, reduce the permanent deformation and viscosity of gross rubber, improve process property. Suitable polymers include NR, IP, SBR, BR, NBR, EPDM, etc.
Crosile® 75 (Bis(3-triethoxysilylpropyl)disulfide) TESPD is a Disulfide Silane Coupling Agent ,polysulfidic organosilane and has been widely in the rubber industry. Crosile® 75 Silane couling agent is used to improve the reinforcing capability of fillers with silanol group on their surface,and also as an integral part of curing systems to improve cross-linking network properties.
One end of its structure with reactive groups such as amino and vinyl, can react with epoxy, phenolic, polyester and other synthetic resin molecules. The other end is alkoxy (such as methoxy, ethoxy etc.) or chlorine atoms which are connected with silicon.
Crosile® 201 is the basic monomer of the silane coupling agent. The product is colorless transparent liquid. It is insoluble in water and can react with water slowly, but easily to trigger hydrolysis cross-linking reaction in the acid or alkaline environment, which is main basic material used in compounding methoxy silane coupling agent.
A comparative study of α- and γ-functional silane coupling agents in silica-filled SBR vulcanized with conventional sulfur systems shows that the effects of silanes on vulcanization kinetics and their coupling effects depend on their structure and location. Rubber reactive groups. All tested silanes containing mercapto or sulfide functional groups resulted in improvements in tensile properties and affected the cure kinetics of the systems used.
Vinyl silane refers to an organosilicon compound with the chemical formula CH2=CHSiH3. It is a derivative of silane (SiH4). The compound is a colorless gas and is mainly of theoretical interest.
Crosile® AK200 Silane is an epoxy-functional silane used as an adhesion promoter and crosslinker in water-based acrylic, epoxy, and polyurethane systems. It enhances adhesion to metal, glass, ceramic, and concrete surfaces, improving coating durability and bonding strength.
