Preform

Preform are long-life road making materials supplied in sheets, rolls, signs etc for easy layering.

Screed

DPI supplies screed in both Hydrocarbon and Alkyd. It is applied with manually operated equipment.

Extrusion

This is another method of marking edge lines and lane lines with a truck mounted machine or trailer transported unit.

Spray

We also supply road marking equipment and materials such as Raised Reflective Pavement Marker’s (RRPM's), Temporary RPMs Cat Eyes and more.

DPI Hot-Melt Thermoplastic


DPI Specializes in producing consistently high quality Hot-Melt thermoplastic conforming to Australia Specification AS4049.2/ AS4049.4 and we can produce to any other specifications required by customers.

Characteristics


The general characteristics of DPI Hot-Melt Thermoplastic are:

  • Excellent long term durability.
  • Good day & night visibility.
  • Environmentally safe including the plastic bag which can be melted with the material.
  • 100% solids, non-toxic, solvent free, (zero VOC)
  • Exceptional heat stability, colour brilliance.
  • High Skid resistance or as required.
  • Rapid, drying time, roads are opened for traffic within minutes after application.
  • Good flow properly.

Backbones


The backbones of Hot-Melt Thermoplastic are basically Hydrocarbon resin or Alkyd resin. Special aliphatic hydrocarbon resin is petroleum based and alkyd resin is derived from a high quality agriculture resin being modified with chemicals. Good quality resins give stable & high quality durable hot-melt products if formulated properly.

Preference


The preference use of one over the other is dependent on end use. Products based on alkyd resins tend to be harder and is impervious to the effect of oil & grease and being renewable these are other advantages, compared with hydrocarbon which depend on non-renewable petroleum derivatives.

One final touch


The other raw materials being aggregates, pigments, glass spheres and modifying resins are carefully selected to give a final product with the required skid resistance, high & durable whiteness, high retro-reflectivity and suitable to the end use. DPI products are formulated to meet the guidelines of the Australian Specification Hot-Melt Thermoplastic AS4049.2 and any other specifications required. In addition, products for other climatic conditions are available.
