Laromer® UA 9089 – A New, Flexible, Weather-Resistant, Monomer-Free Urethane Acrylate

1 887 vues

Publié le

In addition to its perfect adhesion on various resilient flooring substrates, such as luxury vinyl tiles, without showing any curling behavior, this new aliphatic urethane acrylate oligomer exhibits wellbalanced flexibility / chemical-resistance ratio as well as very good weather stability. Laromer® UA 9089 can thus be used for demanding exterior applications, for example automotive headlights and bumpers. Because this new binder is also monomer free, it provides full flexibility in the choice of reactive diluent(s).
