Tokuyama REOLOSIL MT-10C is a hydrophobic fumed silica imported from Japan, surface-modified with methyltrichlorosilane. It has strong thixotropic thickening, efficient reinforcement and powder flow aid, designed for polar systems, suitable for paints, inks, sealants and LED with good compatibility.
Strong hydrophobicity & moisture resistance – silane-modified, hydrolysis-resistant and moisture-proof, greatly improve formula storage stability
Strong thixotropic control – quickly form 3D network, prevent sagging and sedimentation, optimize construction leveling
Efficient reinforcement – ultra-fine particles (5-50nm), significantly enhance mechanical strength and wear resistance of silicone rubber
Powder flow aid & anti-caking – improve powder fluidity, prevent caking, and adjust powder charging performance
High purity & easy processing – extremely low metal ions, fluffy powder without agglomeration, easy to add and process
Paints & coatings – thickening and thixotropy, prevent pigment sedimentation, improve film uniformity and weatherability
Printing inks – stabilize system and prevent sedimentation, endow good colorability, water resistance and printability
Sealants & adhesives – thickening and reinforcement, improve bonding strength, waterproof performance and long-term stability
LED & electronic materials – high purity for encapsulation, ensure insulation and long-term stability of electronic devices
Powder materials – flow aid and anti-caking, adjust charging performance, improve processing and storage convenience
