The cross-linker contains aldehyde groups and the polymer is an alkyd resin or a polyester resin. The carbon-functional groups are acetoacetate groups, malonate groups, acetonate groups or mixtures thereof. Preferably, the polymer is an alkyd resin having said carbanion-functional groups and having a hydroxyl number between 40 and 70 mg of KOH/gram of resin and an acid number between 15 and 25 mg of KOH/gram of resin.
Abstract:
A radiation-curable composition is disclosed. A fluorinated oligomer is combined with a diluent monomer and a photoinitiator to form the radiation-curable coating composition. The fluorinated oligomer is substantially free of isocyanate groups. The radiation-curable compositions provide a suitable coating for substrates, are resistant to penetration by water and liquid hydrocarbons, retain their physical properties over a wide temperature range and exhibit immeasurably low surface friction properties.
Abstract:
The invention relates to a new catalyst composition which is suitable for the polymerization of an olefin and which comprises a reduced transition metal complex and a co-catalyst.
