1. |
The type of material you are considering. (Epoxy, Polyurethane or
Either) |
| |
These products have different capabilities and excel in certain
applications. If you don't know which product is the best, mark the either
option and let us decide. |
|
2. |
Describe the application: (Very Important) |
| |
We need to know your application including whether you are casting,
potting into a container, impregnating or planning to encapsulate a
component. We also need to know the type of components involved and
whether there are pressure sensitive devices such as "Ferrites", Field
effect transistors or glass components in the assembly. Some idea of how
the finished device will function and the environment it will operate in.
We also need to know if any of the components are heat sensitive. |
|
3. |
Handling: |
| |
Dispensing Method: We need to know how you will apply the product. How
it is dispensed will have a major impact on the type of suitable fillers
in the formulation. |
| |
Volume / Part: This is important from the
standpoint of maximum allowable exotherm, minimum pot life and speed of
gellation. |
| |
Amount mixed at one time: Most important if mixed
by hand. You may wish to mix enough for more than one part. This will
effect the minimum pot life required. |
| |
Pot Life: State how long you would like the
material to remain pourable after mixing the resin and hardener together.
|
| |
Gel Time: This is the point at which the material
solidifies and the finished part may be handled with caution. The gel time
is always longer than the pot life and represents the desired time between
pouring the material and being able to handle the component. |
| |
Cure Time / Temperature: The Cure Time indicates to
us the desired length of time for the material to cure. The Temperature is
an indication whether heat curing is available and what is the maximum
temperature obtainable for curing the product. The maximum cure
temperature may be controlled by component limitations or oven
capabilities. |
| |
Mix Ratio by Weight:
You may simply have a
preference or this may be a restriction if you have automated dispense
equipment. (You do not need to specify both mix ratio by weight and
volume, one is sufficient). |
| |
Mix Ratio by Volume: Mix ratio capabilities of
automated dispense equipment is based on either variable or a fixed
ratio by volume. This is important information if you have automatic
dispense equipment. |
| |
Viscosity / Temperature (Resin): Specify if there
are any limitations that you are aware of or you know the viscosity you
need. Viscosity is drastically effected by temperature so if you state the
viscosity, specify the temperature for the viscosity as well. Dispense equipment
may have limitations in this regard. |
| |
Viscosity / Temperature (Hardener): Specify if
there are any limitations that you are aware of or you know the viscosity
you need. If there are no limitations, just leave this field blank.
Viscosity is drastically effected by temperature so if you state the
viscosity, specify the temperature for the viscosity as well. Dispense equipment
may have limitations in this regard. |
| |
Mixed Viscosity / Temperature: Specify if there
are any limitations that you are aware of or you know the viscosity you
need. If there are no limitations, just leave this field blank. Viscosity
is drastically effected by temperature so if you state the viscosity,
specify the temperature for the viscosity as well. Mixed viscosity related
limitations are usually process related. |
| |
Is Vacuum available to de-air the Mix?: The
availability of vacuum is critical in high voltage applications.
This is a formulating consideration. |
| |
Additional Notes on Processing: Provide us with any additional
information regarding your processing preferences or requirements.
|
|
4. |
Cured Properties: |
| |
Shore Hardness: Specify the required shore hardness if known. |
| |
Heat Deflection Temperature (HDT): Specify if
known. |
| |
The Operating Temperature: This is the operating
temperature of the finished part in service. This figure should include
the maximum and minimum temperatures including temporary peaks seen by the
part in service. |
| |
Indoor or Outdoor Service: This is the environment
the part will operate in. A component is considered operating outdoors if
it is exposed to the elements. Operating outdoors but covered from the
elements is still considered indoor operation. |
| |
Thermal Cycling Requirements:
State the extremes in
operating temperatures that the part will see in service. Alternately
state the temperatures the part will be tested to including the number of
cycles, the time at each temperature and the transition time between the
hot and cold cycle. |
| |
Thermal Shock: State the extremes of temperatures
and the number of shocks |
| |
Chemical Resistance: Name the specific substances
the cured material has to be resistant to. Also state how the part will be
tested i.e. 24Hrs immersion etc. |
| |
Moisture Resistance (Test): State the tests that
will be performed to confirm suitability. Alternately, state the
requirements to be met. |
| |
Other Cured Properties:
Provide any other known
cured properties such as : |
| |
-Tensile Strength (psi) |
| -Elongation (%) |
| -Compressive Strength (psi) |
| -Compressive Modulus (psi) |
| -Thermal Conductivity |
| -Flammability Rating |
| -Coefficient of Thermal Expansion |
| |
Electrical Properties: State any and all known
electrical requirements for the part in operation. Enter data such as: |
| -Arc Resistance (Minutes) |
| -Dielectric Strength: (Volts / Mil) |
| -Insulation Resistance: (Ohm-cm) |
| -Dissipation Factor @ Frequency |
| |

Competitive Situation and Planned Volume |
| |
|
| |
Please
provide information about your planned volume requirements, the preferred
packaging and your target price if known. If applicable, describing what
you would like to improve and why will help us satisfy your application. |
