Specific Gravity
Specific Gravity
Specific gravity (SG) is the ratio of the density of a substance to the density of a reference substance; equivalently, it is the ratio of the mass of a substance to the mass of a reference substance for the same given volume.

For liquids, the reference substance is almost always water (1), while for gases, it is air (1.18) at room temperature. Specific gravity is unitless.

Electrical Properties
Breakdown Voltage
Breakdown Voltage
Breakdown voltage is the minimum voltage necessary to force an insulator to conduct some amount of electricity.
It is the point at which a material ceases to be an insulator and becomes a resistor that  conducts electricity at some proportion of the total current. 

After dielectric breakdown, the material may or may not behave as an insulator any more because of the molecular structure alteration. The current flow tend to create a localised puncture that totally alters the dielectric properties of the material.

This electrical property is thickness dependent and is the maximum amount of voltage that a dielectric material can withstand before breaking down. The breakdown voltage is calculated by multiplying the dielectric strength of the material times the thickness of the film.

Volume Resistivity
Volume Resistivity
Volume resistivity, also called volume resistance, bulk resistance or bulk resistivity is a thickness dependent measurement of the resistivity of a material perpendicular to the plane of the surface.

Dielectric Constant
Dielectric Constant
Dielectric Constant (k), commonly known as relative permittivity, is a number relating the ability of a material to carry alternating current to the ability of vacuum to carry alternating current.

It determines the ability of an insulator to store electrical energy and is the ratio of electric permeability in vacuum against the electric permeability of a material.

The lower the dielectric constant (κ) and dissipation factor, the less energy is absorbed from an electric field, making it a much better insulator.

It is a dimensionless property that can be affected by various factors such as the
thickness uniformity of a material, insufficient contact between the sample and electrodes, water adsorption and contact resistance.

Flexural Strength @ 25°C
Flexural strength, also known as modulus of rupture, or bend strength, or transverse rupture strength is a material property, defined as the stress in a material just before it yields in a flexure test. This is the flexural strength tested at Room Temperature, 25°C
>105 N/mm2

Thermal Properties
Coefficient of Thermal Expansion (CTE)
Coefficient of Thermal Expansion (CTE)
CTE (Coefficient of thermal expansion) is a material property that is indicative of the extent to which a material expands with a change in temperature. This can be a change in length, area or volume, depending on the material.

Knowing the CTE of the layers is helpful in analyzing stresses that might occur when a
system consists of an adhesive plus some other solid component.
Coefficient of Thermal Expansion (CTE), α1
Coefficient of Thermal Expansion (CTE), α1
CTE α1 (alpha 1) is the slope of the Coefficient of thermal expansion in a temperature range below the Glass transition temperature (Tg).

It explains how much a material will expand until it reaches Tg.
50 ppm/°C
Gel Time
Gel Time
Gel time is the time it takes for a material to reach such a high viscosity (gel like) that it is no longer workable.

It is usually measured for different temperature conditions and even though it does not refer to full cure it is advisable to never move or manipulate the material after it reached its gel time since it can lose its desired end properties.
Gel Time @ 160°C / 320°F 120 sec
Glass Plate Flow
Glass Plate Flow
Glass plate flow determines the flow distance of thermosetting epoxies, resins or coating powders on a smooth inclined glass surface in a certain time and temperature.

This value is the distance in millimetres from the upper point of the original position of the pellet to the point of extreme flow.

Typically measured at 150°C but please check the TDS for more info

Glass Transition Temperature (Tg)
Glass Transition Temperature (Tg)
The glass transition temperature for organic adhesives is a temperature region where the polymers change from glassy and brittle to soft and rubbery. Increasing the temperature further continues the softening process as the viscosity drops too. Temperatures between the glass transition temperature and below the decomposition point of the adhesive are the best region for bonding.

The glass-transition temperature Tg of a material characterizes the range of temperatures over which this glass transition occurs.
110 °C
Melting Temperature
Melting temperature 58~65 °C

Additional Information

Industrial motors include power tools, home appliances and industrial motors. In automotive, motors are used  for enclosures, windshield wipers, seat adjusters, window lifts and fuel pumps, quality cars can have up to 130 motors. An electric motor is made by wrapping an electric current around a magnetic core, and these two must be insulated from each other.  This can be done by using insulating epoxy coating powder. Epoxy coating powders is widely used due to the advantages of efficiency and reliability. Check our Application Page Slot Insulation for more details.

  High Edge Coverage

 

alt

Epoxy coating powders is likely to be cut by copper wire at the edges. Minimum 300-400um coating thickness and 40% edge coverage ratio are required. MCP-5000 has the edge coverage of 55%.

 

 
  High Adhesion Force

 

alt

Coatings must have a perfect and consistent adhesion to the armature surface. MCP-5000 is tested great adhesion on coppper and Fe-Fe shear adhesion strength of more than 30 MPa

 

 
  Low Pick Up Temperature

 

alt

Lower temperature and faster cure plus great electrostatic pickup increase productivity and save money, MCP-5000 has low melting temperature as 58°C, which allows quick pick up. 

 

Storage

Store in a ventilated, dry, and clean environment below 25°C. Keep away from fire and heat sources. It is strictly forbidden to store in outdoor environments. At proper storage conditions, the product has a shelf life of 6 months.

Precautions

  • Avoid long-term skin contact. Powder that touched the skin should be rinsed off quickly.
  • During operation dust-proof masks should be used to avoid inhalation.
  • Keep the oven temperature stable, so as not to affect the colour and quality of the coating due to excessive temperature deviation.
  • The concentration of dust should be controlled within a safe range to avoid malfunction of the coating equipment.
