A Two-Component (or 2K) Paint Spray Machine is a specialized spray system designed to accurately mix, meter, and apply reactive coating materials at the point of application.

Core Function: These coatings (like epoxies, polyurethanes, polyaspartics) consist of two separate parts:

  • Part A (Resin/Base)

  • Part B (Hardener/Catalyst)

When mixed, a chemical curing reaction begins. Once started, this reaction cannot be stopped, and the mixed material has a limited pot life (e.g., 10 minutes to several hours).

The machine keeps Parts A & B in separate containers or drums. It uses either a proportioning pump or metering cylinders to pull the two components in a precise, pre-set ratio (e.g., 4:1, 2:1, 1:1). The components are then:

  1. Internally Mixed: Combined inside a static mixer tube (a tube with helical elements) just before the spray gun, or…

  2. Externally Mixed: Combined at the tip of a special plural-component spray gun.

This “just-in-time” mixing ensures the material is sprayed immediately after combination, preventing it from curing inside the equipment.

  • Eliminates Pot Life Waste: No need to manually mix batches that might harden before use.

  • Precise Ratio Control: Ensures consistent, accurate mixing for optimal coating performance (cure, gloss, hardness, chemical resistance).

  • Enables Large-Scale Projects: Allows continuous application of 2K materials for floors, tanks, bridges, or large industrial parts without interruption.

  • Consistent Quality: Automated process removes human error in measuring and mixing.

  • Industrial Flooring: Epoxy and polyurethane floors in factories, warehouses, garages.

  • Protective Coatings: Corrosion-resistant linings for tanks, pipelines, offshore platforms, and marine environments.

  • Automotive & Transportation: High-gloss clearcoats, primers, and durable topcoats.

  • Commercial Construction: Durable, chemical-resistant coatings for food processing plants, hospitals, laboratories.

A Two-Component Spray Machine is an essential, precision tool for applying high-performance, chemically-cured coatings on an industrial scale. It solves the fundamental challenge of working with fast-curing materials by mixing them on-demand, right at the spray gun.

Use the equipment’s prescribed ratio-check procedure before production and after relevant adjustments or service. Confirm whether the coating specifies ratio by volume or by weight; the two are not interchangeable without density information. DINO-POWER DP-4336/DP-6536 are listed with a fixed 1:1 volumetric ratio, while the DP-MIX series lists an adjustable 1:1 to 10:1 range. Check measured delivery against the coating supplier’s permitted tolerance. Do not continue spraying an off-ratio mixture: investigate feed restrictions, valves, seals and settings before applying material to the job.

The mixed fluid path must be cleared before the coating’s pot life expires. Where mixing occurs determines which mixer, hose or gun passages require flushing or replacement. DINO-POWER DP-T6512 uses an internal mixing arrangement with a 1:1 ratio, so follow its shutdown and flushing procedure carefully. External-mix models have a different cleanup procedure, but still need nozzle and component-path care. Pot life changes with temperature and material chemistry. Obtain the coating supplier’s data and plan breaks, cleaner quantity and waste collection before starting production.

No. DINO-POWER DP-A8P is explicitly supplied without a heater and is listed at a 1:1 volumetric ratio, 100 bar maximum pressure and 30 m maximum hose length. Some coating systems require temperature-controlled components or heated hoses to achieve the required viscosity and reaction performance. Do not assume a heater-free machine can apply every epoxy, polyurethane or polyurea. Provide the material’s recommended application temperatures and viscosity data so we can determine whether an unheated system is suitable or a different configuration is needed.

Send both component data sheets, ratio and ratio basis, viscosities at application temperature, pot life, required output, hose length and mixing method. DINO-POWER offers different architectures, including fixed 1:1 DP-4336/DP-6536 equipment and adjustable-ratio DP-MIX systems. A broad ratio range alone does not establish material compatibility or adequate mixing. Our R&D team can review the fluid-path materials, heating requirement and flushing arrangement with your coating supplier. For major customers, our eight years of ODM development experience also supports discussion of a tailored equipment configuration.
