A road-marking device which sprays thick ribs of paint to a road surface, transversely to the road axis, to form rumble strips is disclosed.

Road-marking machine

The invention relates to a method for producing a fast drying two or multi-component waterborne coating on a surface of a substrate. The method comprises applying a first component comprising a binder and a second component, being separate from the first component prior to application, comprising an absorber, and compositions and/or formulations prepared therefrom.

Method for producing fast drying multi-component waterborne coating compositions

A method for producing a fast-drying two or multi-component waterborne coating on a surface of a substrate is disclosed. The method includes applying a first component containing a binder composition, and a second component, being separate from the first component prior to application, including an absorber.

Method for producing fast-drying multi-component waterborne coating compositions

A water-borne road marking paint is disclosed characterised in that incorporated within the paint are particles of a solid polymer or inorganic compound, which are capable of absorbing water. Preferred particles are ion exchange resin beads. Incorporation of such particles either during or immediately after application of the paint results in a substantial improvement in the speed of drying of the paint on the road.

Water-based road marking paint

A fast drying traffic paint which includes at least 0.1% by weight, based on the weight of the paint composition, of fibers is disclosed. The paint exhibits reduced cracking during drying. A method for reducing the degree of surface cracking in a fast drying traffic paint during drying is also disclosed. The method comprises incorporating into the paint at least 0.1% by weight, based on the weight of the paint composition, of fibers. Use of at least 0.1% by weight, based on the weight of the paint composition, of fibers in a fast drying traffic paint to reduce the degree of surface cracking during drying of the paint is also disclosed.

Fast drying traffic paints

A water-borne road marking paint is characterized in that incorporated within the paint are particles of a solid polymer or inorganic compound, which are capable of absorbing water. Preferred particles are ion exchange resin beads. Incorporation of such particles either during or immediately after application of the paint results in an accelerated speed of drying of the paint on the road.

Method of drying a water-based road marking paint

A water-borne road marking paint composition which includes a chelating agent capable of chelating iron ions to form a substantially colorless complex is provided. A road marking produced from the traffic paint of the present invention substantially reduces or prevents yellowing of white road marking from iron and iron compound debris strewn on the road surfaces. A method of reducing or preventing yellowing of a newly-applied road marking on a road surface of a water-borne road marking paint is also disclosed. The method comprises incorporating in the water-borne road marking paint a chelating agent capable of chelating iron ions to form a substantially colorless complex. Further reduction of yellowing of the road marking is observed when a pigment dispersant is incorporated in the water-borne road marking paint.
