Road marking

Hydrocarbon resins for road markings and road paints

Q: Is Piroplastic suitable for thermoplastic?

Dryingability must be assessed in the actual formulation, at the actual temperature and by testing. This is neither a universal hot-melt resin nor an automatic replacement for the current binder.

Role in formulation

What is important for marking material

For marking, the visibility of the layer, the opening time of movement, adhesion to the coating and wear resistance are important.

Binder for road-marking formulation

For marking, Piroplast-2K 10–30 and SPS 5/9 are separately evaluated, taking into account the type of material and its colour. For dark resins, additional justification is required: the use in road surfaces does not in itself confirm the suitability for white or yellow markings.

Production applications

Resin test points

Solvent-borne paints and hot-applied thermoplastics are tested according to different modes of preparation and application.

01 Paint

Soluble road paints

The resin is checked in a system of solvents and pigments with a standard method of application.

In the test: viscosity, application, drying, adhesion, colour and storage

02 · Hot system

Thermoplastic marking materials

Check the viscosity of the melt, compatibility, stability during working heating and colour after temperature exposure.

In the test: melting, uniformity, application, cooling and fragility

03 · Layer

Marking formation and visibility

Evaluate the colour and brightness of the finished layer, and for marking with glass beads - retroreflection. The opacity does not exclude the influence of the dark binder.

In the test: colour, brightness, retroreflection, distribution of glass beads and defects

04 · Road

Wear in service

The laboratory selects the composition, but the final decision requires a pilot application.

In the test: adhesion, abrasion, pollution, water and seasonal behavior

What products to consider for road material

Below are products for discussion with the technologist. For each grade, it is necessary to confirm the suitability for the selected type of marking.

Monitoring

Road markings verification programme

A set of methods is tied to the TU of the finished material and the accepted application technology.

Phase	What to measure	Comparison condition
Preparation	Melting or dissolution, uniformity	At standard process temperature
Application	Viscosity, dosing, spreading	On real equipment.
Formation	Drying or cooling, defects of the layer	Until load tolerance
Appearance	Colour, brightness, surface, retroreflectivity	After full stabilisation
Mechanics	Adhesion, fragility, abrasion	On the accepted basis
Field.	Wear, pollution, water, seasonality	At the trial site.

For thermoplastic, stability during working heating, melt viscosity and colour change are checked. After laboratory selection, tests are carried out on the field trial.

Qualification

How to qualify resin for marking material

The laboratory test is needed to the field trial, and the field trial - to serial procurement.

Define the technology

Material type, equipment, base, temperature and opening time of movement.

Choose a batch

Colour, softening and documented resin properties to compare with the existing raw materials.

Make a lab.

Check preparation, application, layer and accelerated indicators.

Run a field trial

Confirm equipment operation, visibility and actual wear.

Boundaries of application

Restrictions on selection of marking resin

If the material’s technology – hot-applied thermoplastic or paint system – is specified only by a generic word with no composition or temperature.
If a very light or transparent binder is required, and the colour of the batch is not allowed by pigmentation.
If the characteristic odor of raw materials is unacceptable and there is no test of the finished material.
If the purchase decision is planned without laboratory application and field trial.

FAQ

Technical and purchasing questions

Purpose of resins, selection criteria and preparation of samples.

Which resin is suitable for road markings?

For the initial evaluation, Piroplast-2K 10–30 and SPS 5/9 are considered. For 60-130 and indene-coumarone resin, separate data are needed to confirm the suitability for marking.

Is Piroplast-2K suitable for thermoplastic?

Suitability must be assessed in the actual formulation, at the actual temperature and by testing. This is neither a universal hot-melt resin nor an automatic replacement for the current binder.

How to check the effect of resin colour?

Evaluate the finished pigmented layer at normal thickness, as well as the colour change after storage and operation.

Is a lab test enough?

No. After the laboratory, a pilot application is needed to test equipment, form a layer and actually wear.

What batch parameters are needed?

Actual colour, softening and other indicators on the documentation for the selected product; the requirements are specified by the marking material technologist.

What to send for selection?

System type, binder composition, solvents or temperature, pigments and fillers, method of application, volume and region.
