Lithene ultra® N4-9000 is a viscous, narrow molecular weight liquid polybutadiene with a low content of 1,2 vinyl micro structure. It is extremely low in both odour and volatiles and can be used as a polyurethane additive to improve abrasion resistance.
Polyurethane additive for abrasion resistance
Automotive sound damping sealants & adhesives
Dry sand binder
Lithene ultra® N4-9000 is despatched from our UK production plant.
Handling - Lithene ultra® N4-9000 is a viscous liquid polymer. The viscosity of the product will decrease rapidly with increased temperature and the product may be warmed to allow easier processing.
Compatibility - Liquid polybutadienes are generally compatible with most aliphatic and aromatic hydrocarbon solvents. They have limited solubility in alcohols, ketones and esters. Further details are available on request
Lithene ultra® N4-9000 can be oxidatively dried by heating thin films at 160 - 200°C or by use of metallic driers, to give hydrophobic coatings with good adhesion. Combination with metallic driers also allows the product to act as a binder for dry sand.
Lithene ultra® N4-9000 can be incompatible with many polar systems making it suitable for use in the formulation of PU mould release coatings and as an additive in PU moulding systems to improve abrasion resistance.
With a very low level of residual volatile compounds, Lithene ultra® N4-9000 is also recommended for the formulation of heat cured automotive sealants and adhesives.
Further application and formulation advice is available on request.
