Lo-4282 Flow and Leveling Additive
Composition:This product is specia modified polysiloxane with primary hydroxyl groups. Can react with polyurethane prepolymer. As a
polyurethane modifier, it can improve the resin slip and anti-adhesion properties.
Typical data:
- Appearance:pale-yellow coored clear liquid.
- Active matter content:100%
- Refractive index at 25ºC:1.425-1.430
- Viscosity(25ºC):100-200cp
- Excellent anti-sticking and stripping.
- Reduce surface tension, improves wetting of release paper and substrate, enhance leveling, anticratering and pinhole of
resin. - Increase the softness . Provide sleek surface and smooth handle for PU synthetic eather.
- Improve air permeability and mosture permeability.
Improve abrasion resistance and flex resistance at low temperature. - Compared to other organic modifier, Lo-4282 has better compatibity with polar solvents ,such as PU resins and DMF.
Suitable for polyester system, react with isocyanate very well and get lasting modification effect.
Lo-4282 is a recative agent. Add the product reacted with isocyanate int the earlier stage of PU resin production, thus to
achieve lasting modified effect on properties of PU eather. In addition, Lo-4282 is added in the later stage of PU resin
production or the earlier stage of PU synthetic leather production, which also can get better results.
- 0.1-0.5% on total formulation as leveling additive.
- 1%~5% as a resin modifier.
Available in 25 liter pail and 200 liter drums. 24 months in closed containers
