Structure types

Composite and structure characteristics

Properties

sol type

more oil components and resin, thick external film of the micelle, free movement

among micelles

more oil components and resin, thick

external film of the micelle, free movement

among micelles

sol-gel type

closer among micelles and have attractive force each

other

Between

sol type and gel type

gel type

Less oil components and resin, thin external film of

the micelle, difficult movement among micelles

better elasticity and viscosity, low

temperature stability, mobility and plasticity
