Abstract

A review is presented of highway traffic marking paint used in california, and the equipment used to apply these paints. At the present time a resin-oil-chlorinated-rubber combination of traffic lacquer is favored. Production has been increased using this compound, but further experience during the rainly season is needed before final approval. Another formulation which shows considerable promise is pliolite (styrenated butitadiene) with a mixture of chlorinated paraffins. This product has exceptional possibilities in unbeaded lines for crosswalks, etc., but it is found to be a relatively poor holder and some difficulties were experienced in securing proper viscosities for uniform application. It is concluded that it is desirable to make a study of polyvinyl chloride for each vehicle. An optimum PVC has been found which is a compromise between durability and drying time requirements. PVC gives better durability if the stripe is allowed to dry and bead retention is somewhat better. Epon, vinyls and possibly ethyl cellulose used in combination are viewed as new prospects.
