Eliminating Corona Discharge and Internal Component Arcing

High-voltage equipment suffers from localized electrical discharges when air gaps exist inside the insulation. Over time, Internal Component Arcing breaks down material walls, causing total equipment failure.

Our insulating epoxies prevent electrical tracking and internal discharge

  • Air Pocket Elimination: Fills tiny spaces inside cases, coils, pasteurized sender and receiver to remove air pockets.
  • Arc Resistance: Avoids the formation of surface carbon paths under a heavy electrical load.
  • Voltage Shielding: Allows a very high insulation resistance to be maintained in the face of a steady electrical load.
  • Stable Permittivity: Exhibits consistent electrical properties over a wide frequency spectrum.

The combination of these protective characteristics prevents early dielectric failure over long operating periods protecting both transformers and switchgear.

Complete Environmental Isolation from Moisture and Chemical Ingress

Outdoor power lines, marine equipment and all factory controls in harsh environments are subjected to rain, salt air and fumes from chemicals. Water ingress results in cables corroding and short circuiting.

Our epoxies deliver complete Environmental Isolation

  • Moisture Barrier: Prevents water from entering by blocking the moisture ingress to protect the internal active circuits.
  • Chemical Shield: Chemical ingress such as corrosive, acid, solvent, fuel are prevented.
  • Dust Block: Seals enclosures from delicate industrial dust and conductive grit.
  • Corrosion Protection: Prevention against the oxidation of the joints in sealed containers or oxidation of copper wires.

Providing total environmental defense ensures long service life for electronics operating in harsh outdoor or factory settings.

Solventless Impregnating Resins for Electric Motor and Generator Windings

Rotating motors and Power Generators operate under the influence of centrifugal forces, heat, and high vibration. Consequently, the windings need a large fixture to keep the wire from chaffing or moving.

Our solventless resins protect Generator Windings and industrial motor coils

  • Solid-State Curing: Cures 100% with no solvent vapours released or pinholing.
  • High Wire Bond: Holds up the copper wires so they don't move against the magnetic attraction.
  • Heat transfer: Uses internal heat from deep windings for dissolving to cooling fins.
  • Smooth Dipping: Delivers a smooth barrier coat in all positions when trickling vacuum-pressure impregnation (VPI) steps.

The protection of motor windings ensures longer equipment life and undoubtedly reduces maintenance at industrial sites.

Our Specialized Formulations for Electrical & Electronic Subsystems

Modern power hardware uses complex layouts with tight spaces and dense wiring. Standard generic materials fail to fill tiny gaps or handle deep pours. Veeyor Polymers engineers Specialized Formulations designed for complex Electronic Subsystems.

Working directly with experts in Epoxy for Electrical Insulation helps you optimize processing speed and eliminate internal defects.

Void-Free Encapsulating Resins for Heavy-Duty Transformers and Switchgear

Large electrical coils require thick liquid insulation that flows deep into dense wire windings. Trapped air inside a transformer core causes dangerous hotspots and arcing risks.

We produce Void-Free Encapsulating Resins for Heavy-Duty Transformers

  • Deep flow: feeds every turn of the coil in the right direction, enabling it to fully pervade any empty spaces.
  • Low Exotherm Heat: Controls the amount of heat released when cure occurs for large molds with deep pours.
  • Vibration control: diminishes the magnetic hum and measurable noise while in use.
  • High thermal limit: resistant to high working temperature without softening and depletion.

Epoxy for Electrical Insulation is used to prevent transformer failures and to provide a continuous supply of grid power.

Preventing Dielectric Breakdown with Tailored Epoxy Insulation

The electrically used equipment needs insulation, which will cope with very high voltage, spikes of high temperature, and mechanical shock. Our tailored epoxy insulation above alloys gives maximum dielectric protection together with high physical strength in many factors. All our compounds are designed to comply with international electrical standards and very strict safety regulations.

An electrical epoxy depends on a carefully balanced reaction between a resin base and a liquid hardener. Once mixed, the two components combine to form a thick, highly cross-linked network. This network prevents current flow, dissipates heat, and seals off the ingress of atmospheric moisture.

Key performance features built into our Custom Formulations include

  • Excellent dielectric strength: avoiding electrical failure and current leaks over tightly packed leads.
  • Low Thermal Shrinkage: Maintains the correct shape of the mold, hence avoiding internal stress during this process.
  • Thermal Dissipation: dissipates heat from the hot internal components to stops the Circuit from frying.
  • Chemical resistance: Guards sensitive instrumentation against oils, solvents and fumes from industry.

We customize each formulation to meet your specific processing. Whether your plant uses manual pouring or fast automated meters, our resins flow smoothly and cure on time.

Withstanding Rapid Thermal Cycling Without Micro-Cracking

During operation, electrical components are subjected to constant ups and downs of temperature, which causes it to expand and shrink. Sensitive, rigid, and brittle materials tend to develop microscopic cracks that allow the entry of moisture, resulting in short circuits.

Our resilient formulas handle heavy thermal stress without cracking

  • Flexible Backbone: Unites the molecule to insulate the internal stress on the molecule generated by Thermal Cycling.
  • Matched CTE: Matches the coefficient of thermal expansion for copper, aluminum and steel parts.
  • Crack Resistance: Stops microcracks from developing in the event of a rapid temperature change.
  • Long-Term Hardness: Maintains complete mechanical properties after several thousand heat cycles.

Prevents micro cracks, preserves dielectric strength and secondary wires throughout years of active field operation.
