Your All-in-One Solution for Circuits, Repair, and EMF Shielding

0.1–0.5 Ω/sq Water-Based Low-VOC Engineered in USA

Tired of complicated electronics or messy soldering? SilexCore Conductive Paint is a highly conductive, non-toxic, water-based formula that works like a "liquid wire" — letting you draw circuits, repair damaged PCB traces, and shield electronics from EMF without a single solder joint. Whether you're a student building your first circuit, a maker repairing a guitar cavity, or an engineer prototyping a new design, this paint makes conductivity accessible, clean, and fast.

What Makes It Different

Versatile Circuitry & PCB Repair

Use it for everything from delicate PCB trace repairs to complex electronic art and sensor prototyping. Bridge a broken trace, draw a new circuit path, or bond a lifted pad — all without heat or flux. It's the ultimate liquid wire for any project.
Safe, Non-Toxic & Eco-Friendly

Our water-based formula is 100% non-toxic and free of heavy metals, making it the safe choice for homes, schools, and professional workshops. Clean up with just soap and water before the paint cures — no solvents, no fumes, no PPE required.
Fast-Drying & Simple Application

No special tools required. The paint becomes touch-dry in about 30 minutes at room temperature and reaches full electrical conductivity once completely cured (typically 24 hours). Apply with the precision pen tip, a brush, or screen-print it — your choice.
Universal Bonding Across Multiple Surfaces

Engineered to adhere to almost anything — paper, cardboard, wood, drywall, glass, most plastics, and metals. The formula forms a durable conductive film that stays put without peeling or cracking under normal indoor use conditions.
High-Performance EMF & EMI Shielding

Provides reliable conductivity and strong EMI shielding performance. Multiple coats increase attenuation — a single layer delivers up to 40 dB, two layers reach 48 dB, and three layers achieve 54 dB of EMF shielding effectiveness. Widely used for guitar cavity shielding to eliminate hum and noise.

Applications

Printed Electronic Circuits: Create functional circuits directly on paper, cardboard, fabric, or PCB without any soldering.
PCB Trace Repair: Fix damaged or broken circuit traces quickly and efficiently — no rework station needed.
Electronic Prototyping: Develop and test new circuit designs without complex manufacturing or etching processes.
EMF & EMI Shielding: Reduce electromagnetic interference and protect sensitive electronics, instruments, and enclosures.
Guitar & Instrument Shielding: Line cavity interiors to eliminate single-coil hum and noise pickup.
STEM Education & DIY: Perfect for classroom projects, hands-on learning, and interactive electronics experiments.

Compatible Surfaces

Paper and cardboard
Plastic and glass
Wood and drywall
Metals and coated surfaces

Usage Guidelines

Designed for indoor use only
Apply on clean, dry surfaces for optimal conductivity
Allow full drying time before testing circuits or measuring resistance
Multiple thin coats produce better results than one thick coat

By the numbers.

Technical Data

Sheet Resistance

0.1Ω/sq

Minimum on smooth, non-porous surfaces. Typical range 0.1–0.5 Ω/sq depending on substrate and film thickness.

Touch Dry

30min

At room temperature, ~70°F / 21°C. Apply heat to accelerate: 5–10 min at 150°F / 65°C.

Full Cure

24hr

Full electrical and mechanical properties at 24 hours at room temp. Test conductivity after full cure for best results.

Film Thickness

50µm

Typical single-coat wet film. Multiple coats reduce resistance proportionally.

VOC Content

LowVOC

Water-based carrier. No heavy metals. Suitable for classroom, home workshop, and lab environments. See SDS for full profile.

Substrates

10+

Paper, cardboard, fabric, PCB, glass, metal, plastic, wood, ceramic, and more. Adhesion varies — test before committing.

Electrical Conductivity

The following measurements demonstrate the sheet resistance of the conductive paint at varying thickness levels, ensuring flexibility for different applications such as circuit design and PCB repair.

Test #	Thickness	Min Resistance	Max Resistance
1	20 µm	2.0 Ω/sq	4.0 Ω/sq
2	100 µm	0.5 Ω/sq	1.0 Ω/sq
3	200 µm	0.1 Ω/sq	0.5 Ω/sq

EMF Shielding Effectiveness

SilexCore Conductive Paint provides strong protection against electromagnetic interference (EMI). The shielding performance increases with additional layers, offering significant attenuation and reduction of electromagnetic signals.

Layer #	Attenuation	Effectiveness	Reduction Factor
1	40 dB	99.99%	10,000
2	48 dB	99.9987%	63,096
3	54 dB	99.9996%	251,188
