⎯ ELECTRONIC MATERIALS

Our Electronic Materials Are Manufactured to
Individual Customer Requirements Upon Request.

⎯ GRIGNARD REAGENTS

Not All Grignard Reagents Are the Same.

Quality and supply reliability are key considerations when selecting a Grignard reagent.

Continuous manufacturing delivers a measurable difference in quality and supply reliability.

Two Key Factors in
Grignard Reagent Selection

Continuous production is more than a different manufacturing method. It provides the foundation for consistent quality and reliable delivery across repeat orders.

⎯THREE QUALITY BENEFITS

Three Quality Benefits of Continuous Production

Precise process control minimizes key impurities that can affect downstream reactions.

SELECTIVITY

Reduced Wurtz Coupling By-Product Formation

Higher Grignard selectivity significantly reduces homocoupling by-products and lowers downstream purification requirements.

CONVERSION

Reduced Residual Halide

Full conversion of the halide precursor minimizes residual R–X that could interfere with downstream reactions.

PURITY

Reduced Solid Carryover

Reduced carryover of Magnesium fines and inorganic salts supports more stable downstream processing.

⎯ BATCH VS CONTINUOUS

What Makes Continuous Production Different

Real-time process monitoring and automated control allow deviations to be identified and managed during production rather than detected after production.

Category	Conventional Batch Process	Continuous Production
Quality Variation	Lot-to-Lot Variation	Steady-State Continuous Operation
Quality Testing	Post-Production Sampling	100% In-Line Monitoring Using NIR and Density Measurements
Out-of-Spec Material	Detected After Production; Potential Lot Loss	Automatically Diverted and Discharged Before Collection
Wurtz By-Products	Relatively High	Significantly Reduced
Unreacted Halide	May Remain	Complete Halide Conversion
Solids	Potential Carryover of Mg Fines & Salts	No Solids Carryover
Concentration Options	Primarily Standard Concentrations	Adjustable from 0.25–3.4 M
Production Scale-Up	Additional Reactors Required	Extended Run Time or Numbering-Up

⎯ GRAPHENE COATED COPPER

Oxidation-Resistant Copper
Graphene-Coated Copper Powder

Our expertise in graphene led to a solution for thermal management materials.

⎯ GRAPHENE APPLICATION CHALLENGES

Three Key Challenges
in Industrial Graphene Applications

Graphene offers exceptional properties, but agglomeration, limited loading,
and challenges in paste formulation can restrict its industrial applications.

01

AGGLOMERATION

Agglomeration & Settling

trong interlayer forces between graphene sheets can cause agglomeration in solvents or resins and lead to settling over time.

02

Limited Graphene Loading

Achieving higher graphene loading can be difficult, limiting the amount that can be incorporated to achieve the desired material performance.

03

PROCESSABILITY

Paste Formulation Challenges

Achieving a stable paste formulation can be difficult, limiting its application in manufacturing processes.

Unlocking graphene’s full potential requires stable dispersion and the ability to use it at high concentrations.

⎯ EVERPHENE DISPERSION

Everphene™: Stable Dispersion & High Concentration

Surface treatment of the graphene maintains dispersion stability, enables concentration control from 1–50%,
and allows use in high-concentration inks and pastes.

Category	Conventional Graphene	Everphene™
Concentration	1% or Less	Adjustable from 1–50%
Paste	Very Difficult	Paste Formulation & High-Concentration Ink Applications
Applications	Limited Application in Thermal Management, Heating & Printed Electronics	Suitable for a Wide Range of Applications

Graphene that can be processed at high concentrations can be used to coat the surfaces of other materials.

How the Coating Process Works

Each particle is individually coated, providing full surface coverage without agglomeration or uncoated areas.

Surface-Modified Copper

Coating with High-Concentration Graphene

Uniform Surface Coverage

⎯ SCALABLE PROCESS

From Research to a Mass-Production-Ready Process

A simple, high-productivity process enables Graphene-Coated Copper production to scale up to mass production.

Uniform Coating

A uniform graphene layer covers the entire surface of each particle.

Oxidation Protection

Reduces oxidation of the copper surface, improving the stability of thermal management materials.

Scalable Production

Production can be scaled up to mass production without complex multi-step processes.
