On the product

Why indene-coumarone resin is injected into an industrial mixture

The product is selected for dark systems and evaluated by a specific function: rubber processability, bitumen modification or foundry binder operation.

Sample product Indene-coumarone resin — Product illustration. The actual appearance and values are confirmed by the certificate of analysis.

Processing resin for compounding and binders

Indene-coumarone resin is used in rubber and tire mixtures, polymer-bitumen and road materials, foundry formulations and mixtures for targets. The same documentation range does not mean the same result in different matrices: the type of rubber, bitumen, filler and process temperature require separate checks.

determine the function of the resin in the current formulation;
select softening for equipment and process;
check the compatibility, dispersion and properties of the product;
We accept the batch only on the current documentation.

Applications

For what production tasks is the product suitable

The colour of the product makes it a rational candidate primarily for opaque and dark compositions.

01 · rubber products

Rubber mixtures and technical products

Resin is qualified as a processing component in the customer's own compounding process of rubber compounds.

In the test: mixing, dispersion, stickiness, vulcanisation and physical-mechanical properties.

02 · Tyres

Tyre rubber compositions

The product can be included in the testing program of the tyre plant if it has its own laboratory and criteria for a particular mixture.

In the test: processing, cohesion, vulcanisation behavior and sample properties.

03 · Bitumen and roads

Polymer-bitumen binders

Indene-coumarone resin is considered as a modifier of dark bitumen systems and road materials.

In the test: compatibility, processing temperature, heat resistance, adhesion and storage.

04 Cast

Moulding mixtures and special products

In foundry mixtures, the role of the resin as a carbon-forming additive or a component of the binder composition is specified. Evaluate the gas formation and quality of the casting surface.

In the test: formability, gas yield according to the method, casting surface and knockability.

Selection

What to agree before testing indene-coumarone resin

Not only is softening important, but also the matrix, process and measurable requirements for the finished product.

Specification

Technical characteristics of indene-coumarone resin

Catalogue limits are required for primary qualification. The actual values are confirmed by the documentation for the proposed batch.

Indicator	Range/status	What to verify
Softening point, °C	75–145	The actual value of the batch
Acid number, mg KOH/g	Not more than 1.0	Result and method of batch inspection
Iodine number, g I2/100g	Not more than 50	Result and method of batch inspection
Mass fraction of water, %	Not more than 0.3	Result and method of batch inspection
Mass fraction of volatile substances, %	Not more than 0.3	Result and method of batch inspection
Brilliant carbon, %	At least 50	Method, conditions and calculation base of the indicator
Mass fraction of ash, %	Not more than 0.1	Result and method of batch inspection

For the indicator of lustrous carbon, the method and calculation base for the documentation of the plant are specified. It characterizes carbon formation during heating, and not the content of the finished carbon filler in the resin.

Qualification

How to qualify a product for your matrix

The test program should repeat the current process and compare the product with a clear control.

Select a function

Note why the resin is introduced and what property should change.

Check documents

Compare the batch CoA with the current raw material and processing window.

Make a lab mix

Keep the same equipment, mode and other components.

Check the product

Evaluate the production process and the target properties of the finished sample.

Boundaries of application

When indene-coumarone resin is not the first choice

For transparent and light decorative materials, where the dark colour of raw materials is unacceptable.
For tasks with critical odor requirements without separate testing of the finished product.
If a ready-made technological recommendation is required without data on rubber, bitumen or binder.
If you intend to directly copy the dosage of another product without a comparative test.

FAQ

Selection, testing and supply issues

Characteristics, tests and conditions of order.

Where is indene-coumarone resin used?

In rubber and tire mixtures, polymer-bitumen and road compositions, foundry binders and special moldable compositions.

How to choose the softening point?

Provide the target property of the current raw material and the process conditions. We will select an available grade within 75–145 °C and confirm it with the batch CoA.

What does lustrous carbon mean at least 50%?

Lustrous carbon is formed during the thermal decomposition of organic additives and affects the casting surface. The value of ≥50% is given in the catalogue; the method, conditions and calculation base should be specified from the documentation of the plant.

Is the product suitable for light coating?

Generally not: the product is dark and focused on opaque industrial systems.

Is it possible to replace the current processing resin?

Only after laboratory and production comparison. You need to check the dosage, processing and properties of the product.

What do you need for a quotation?

Specify the application, matrix, current product, softening required, volume and region. Then the documentation, sample and delivery conditions are agreed.
