Tokuyama REOLOSIL PM-20L is a hydrophobic fumed silica imported from Japan, surface-modified with polydimethylsiloxane. It features strong hydrophobicity, high thixotropy and excellent rheological stability, specially designed for polar solvent systems like epoxy, polyurethane and vinyl ester resins.
Strong hydrophobicity & hydrolysis resistance – silicone-modified, moisture-proof for outdoor applications
Excellent polar system compatibility – suitable for epoxy, polyurethane and vinyl ester resins
Efficient rheology control – form 3D structure quickly, prevent sagging and settling
Ultra-high purity – low metal ions, ideal for LED and electronic encapsulation
Easy dispersion – fluffy powder without agglomeration, easy to add and mi
Industrial paints & coatings – thickening & anti-settling for polar systems
Printing inks – enhance thixotropy and dispersion for better printing effect
Sealants & adhesives – thickening and reinforcement, improve bonding strength
LED & electronic materials – high purity for encapsulation with good insulation
Organic elastomers – efficient reinforcement for better mechanical properties
