Method of curing 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.

Method of reducing yellowing of water-borne road marking paints and

The present invention is directed to producing a luminescent screen used in a cathode ray tube (CRT) suitable for monochromatic or chromatic images, such as, those utilized in televisions, computers or data monitoring equipment, which require CRTs. The method of the present invention produces an ablative layer of the luminescent screen having a smooth surface with reduced surface distortions, such as, streaks and waviness, which are typically produced by conventional coating processes. When a reflective aluminum film is deposited on such a smooth ablative layer, the reflective aluminum film is also provided with a smooth surface, since it typically conforms to the underlying smooth surface of the ablative layer. As a result, CRT images having reduced distortions are produced. The method of the present invention further provides for enhancing the brightness of CRT images, which results from utilizing low ash producing polymers in the ablative layer and the binder of a luminophor layer of the luminescent screen. The method of the present invention further provides for combining the step for volatilizing of the ablative layer and the binder in the luminophor layer with the step for cementing of the face plate of CRT with the cone of CRT, without adversely affecting the quality of the hermitic seal between the face plate and the cone.
