The paste conforms to surface irregularities to help reduce interfacial air gaps. Fine square filler outlines are shown schematically within the paste. Surface roughness, particle size, spacing and layer thickness are exaggerated for explanation; this is not microscopy or a measured void-fraction result.

Elite forms the thermal interface between a heat-generating component and its cooler. The compound fills surface irregularities at the contact joint, supporting heat transfer into a heatsink or cold plate.
Its gray, square nano-diamond formulation combines filler design with surface-modification technology and metal-surface wettability.
JunPus identifies high-performance CPU and GPU cooling, gaming PCs, workstations, servers and high-performance computing systems among its intended applications.
THE ELITE FORMULATION
Formulated for surface contact.
Elite’s square nano-diamond formulation brings together surface-modified filler and a carrier system formulated without small-molecule solvents. These material characteristics guide application and process evaluation.
Magnified material concept. Square filler outlines, spacing, surface roughness and proportions are illustrative, not microscopy or a measured particle-size distribution.
Square nano-diamond formulation
The technical data describes morphology refinement and micro-alloy doping as the filler-surface modification methods.
Metal-surface wetting
The formulation is designed to wet metal contact surfaces, helping establish the interface between a component and its cooler.
Controlled application
Screen printing is a documented application option. Evaluate coverage and process settings for the intended contact area.
CPU / GPU / LIQUID COOLING
At the heart of the cooling path.
The thermal compound works at the solid contact joint between the processor and cooler. Evaluate Elite for your heat source, cooler design and assembly process.
Application concept: cold plates are lifted to reveal thin, spread paste layers on a CPU heat spreader (left) and a bare GPU die (right). Layer thickness and hardware details are illustrative. Confirm compatibility with the actual hardware.
CPU COOLING
Between the heat spreader and cooler.
Evaluate Elite for the grease interface between a CPU’s integrated heat spreader and the contacting base of a heatsink or cold plate. Gaming PCs, workstations and server systems are among its intended applications.
GPU COOLING
At the processor-to-cooler interface.
High-performance GPUs are also an intended application. The illustration shows paste at a bare GPU die-to-cold-plate interface. Follow the board maker’s requirements for the actual package and retain specified thermal pads on surrounding components.
LIQUID COOLING
Into the cold plate.
In a liquid-cooled assembly, the thermal paste transfers heat across the processor-to-cold-plate interface. The cooling loop carries that heat onward from the cold plate.
Application examples describe intended use. Confirm suitability for the exact hardware and assembly process.
SELECTION & APPLICATION
Start with your assembly.
Select the compound based on the component, cooler and application process, then evaluate it under representative operating conditions.
Define the contact surfaces.
Identify the component surface, cooler material, contact area and hardware mounting requirements.
Plan the application process.
Establish the application method, paste quantity, coverage and assembled bond line.
Set the operating context.
Consider the expected workload, thermal cycling and service requirements when planning evaluation.
Confirm the product supply.
Check the current specification, required pack format and storage instructions with JunPus.
VISCOSITY AT 22°C3,900,000 mPa·s
A reference for evaluating application equipment and process settings. Screen-printing parameters and paste coverage should be established for your assembly.
Prepare, apply and verify.
Follow the hardware manufacturer’s cleaning and mounting instructions. Verify paste coverage and cooler contact, then check thermal behavior under a representative workload.
Published storage condition: 20 ± 5°C. Follow the supplied product label and current handling instructions. Laboratory test pressures are not processor-mounting instructions.
For formulation or viscosity requirements, share the target range, measurement temperature and method with JunPus. Ask which existing products and technical data are available for evaluation.

A nano-diamond and silicone-based compound. Start here when reviewing the family catalog’s printing and coating applications, then confirm the product and process requirements with JunPus.
A nano-diamond and silicone-based compound with screen-printing and dispensing applications described in its technical documentation. Consider it when evaluating those application processes.
A square nano-diamond formulation with documented metal-surface wettability and screen-printing suitability. Evaluate it for CPU and GPU interfaces that need close attention to surface contact and assembly conditions.
These starting points are not exclusive uses or performance tiers. Confirm the current specification, application process and assembly results before selection.
Selection guidance, with the test context intact.
These are manufacturer-listed properties, not a controlled head-to-head benchmark. A thermal-performance comparison requires matched pressure, temperature, bond line and test method. Density alone does not rank cooling performance.
IDEALIZED 2D MODEL / NOT PRODUCT TEST DATA
Shape changes the geometry.
Equal-width round and square profiles leave different gaps on the same square grid. This simple model explains a geometric idea. It does not measure the packing or cooling performance of any JunPus formulation.
Round profiles
78.5% planar area coverage
21.5% of the cell area remains uncovered.
Ideal square profiles
100% planar area coverage
No uncovered area in this ideal tiling.
21.5 percentage points of geometric difference.
This is a difference in calculated two-dimensional area coverage, not an improvement in thermal conductivity, CPU temperature or actual filler packing. Real powders contain three-dimensional particles, a binder and a size distribution.
Model assumptions and calculation
Both panels use 16 profiles on a square grid with pitch d. Each circle has diameter d; each square has side length d. Circle coverage is π ÷ 4 ≈ 78.5%. Square coverage is 100%. The difference is 100 × (1 − π ÷ 4) ≈ 21.5 percentage points.
The shapes have different material areas, so this is not an equal-filler-content comparison. No binder thickness, particle-size distribution, surface roughness, pressure or three-dimensional packing is modeled. The round arrangement is not optimized. These calculations do not verify the brochure’s approximately 25% gap-filling claim.
