The manufacture has required a large equipment and a long time heating, and has sufiered from an economical problem as well as the deterioration of the marking materials by heating. The mixture was stirred so that the glass sphere may be coated with D.O.P. If less than 2.5 parts by weight of the ethylene-vinyl ester copolymer are used in the melt bonding type road marking paint compositions to be produced, the resulting paint compositions will not exhibit an improved fluidity when melted nor will they give coatings having an improved impact strength and flexibility, thereby rendering the paint compositions undesirable as such. Moreover, the process contains a dangerous operation at a high temperature. Fast-drying is also tested in the field. C0815 45/04; E01c 23/16 U.S. Cl.

H. The mixing of the nucleus component with the liquid component is completed so that thenucleus. A hot-melt type road marking wax-free paint composition according to claim 1, wherein the ethylene-vinyl ester copolymer, the pigment and the filler are present in amounts by weight of 5-30 parts, 30-80 parts, and 100-400 parts, respectively. sieve, a lubricant, an antioxidant, and an antiblocking agent, and mixtures thereof; wherein about 3-75% by weight of said ingredients is in the form of relatively large particles selected from pellets, beads, and granules and constituting a nucleus component selected for the group consisting of said aggregate of silica sand and said glass spheres, the steps comprising: first adding said liquid plasticizer at one time to said nucleus component with mixing, but without heating or melting, to coat said nucleus component with said plasticizer, and. Submit a Request for Proposal (RFP) to suppliers of your choice with details on what you need with a click of a button. The plasticizer is usually added in amounts of not more than 30 parts by weight per 100 parts by weight of hydrocarbon resin and is illustrated by customarily used in animal, vegetable and mineral oils and synthetic oils, such as liquid paraffin, a phthalic acid ester and castor oil. Claim this business. Thermoplastic paint for road markings is part of the family of thermoplastics, a compound of synthetic resins that hardens when cooled.

No abrasives to damage concrete or asphalt. From the results of Table 2, it is seen that the melt bonding type road marking paint compositions of this invention successfully meet the requirements prescribed in JIS K-5665 and have properties approximately equal to those of the commercial paint compositions containing the conventionally recommendable maleinized rosin. Because performance is so crucial and the process so precise, BASF chemists emphasize the need to test paints for the wide array of conditions theyll face in the end users hands. The lubricant is added to reduce the viscosity of the product on heating and make the product sprayable particularly when EVA or EEA is contained.

Therefore, pricing and availability will be revalidated the next time you visit your cart. ACRONAL Xpress 4347, an all-acrylic copolymer, comes from a line of proven latex technologies developed by BASF. data. The above vehicle has generally an excellent thermal resistance, but it is feared that the heating for a long period of time in the manufacture andthe repeated heating in the applicationmay cause the deterioration of the product. (5) Additive component, this term meaning herein lubricants such as paraffine wax, polyethylene wax, other synthetic waxes, etc. A hot-melt type road marking paint composition according to claim 1, wherein the pigment is a white-colored pigment selected from the group consisting of titanium dioxide, zinc oxide, leaded zinc oxide, zinc sulfide, lithopone, antimony trioxide, rutile calcium composite pigment, basic carbonate white lead, basic carbonate white lead, basic sulfate white lead and basic silicate white lead. Anything we do in the lab is supposed to simulate field conditions, Burghart explains. Among these conventional paint compositions, the so-called melt bonding paint composition is a normally solid and solvent-free type, one which contains as essential components a thermoplastic resin adn a pigment and also contains, for example, a plasticizer, stabilizer, antioxidant and filler as well as glass beads as required. The coating or cake so formed was bent for its flexibility. Thats a big part of adding durability to the end product.. National Transportation Products Evaluation Program. All the other road marking paints and materials produced Qd service lives of approximately one year. Thermoplastic Road Marking Paints We are engaged in offering an extensive range of Hot MeltThermoplastic Road Marking materials for highway line markings . When heated, the mixture moves into a liquid state and is applied either by spray or extruded on the road ranging from 90 to 120 mils depending on the specification. Even so, thermoplastic road paint formulations typically consist of polymer resins, a binder, glass beads for reflectivity, and pigments. Teniseal offers services for Baltimore, Anne Arundel, Howard, Prince Georges, Harford, Carroll, and Montgomery counties in Maryland.

When the paint composition of this conventional type is to be used in the formation of, for example, thick film-type road marking such as indicating lines, this is accomplished by melting the paint composition at temperatures of as high as 150-250C, applying the molten composition to a road surface so that it forms the desired shape and then allowing the applied composition to cool. BASF matched 60 seconds of dry no-track time during the National Transportation Products Evaluation Program (NTPEP) in Florida, says Chan. End users want paints that last longer on the road before they need to be re-applied, allowing them to maintain safe road conditions for longer stretches of time. Superior reflectivityup to 600+ mcd (white) and 400+ mcd (yellow), Special profile systems for wet and night reflectivity, Intermix beads provide reflectivity throughout the life of the line, Audible and rumbleformulations available, Tests show superior product lifetimes of 8 and more years versus 1-2 years for conventional paint markings, Reduced maintenance costs, longer lifetime and hence also less obstruction of traffic due to reapplication of markings, Free from volatile organic compounds / solvent.
