  • Encapsulating Photopolymer
  • Prevents Silver migration
  • Fast UV Cure

Product Description

LOCTITE EDAG PF 021 E&C encapsulating photopolymer is designed to secure low profile surface mount devices (SMD) to rigid or flexible substrates. It is particularly effective for use as a physical and environmental protection of the mounted device.

LOCTITE EDAG PF 021 E&C is a UV curable, clear thermoplastic with a fast UV cure that prevent silver migration and physically protects SMD. It offers ease of process and dot dispensing with a max operating temperature of 204°C.

Technical Specifications

General Properties
Shelf Life
Shelf Life
Shelf life is the amount of time after manufacturing that a product is guaranteed to retain its properties.

It differs vastly per product and it is based on temperature and storage conditions.

The properties can be guaranteed for the temperature and time range indicated on the TDS since those are the ones tested to be the best for the product.
Shelf Life @ 25°C 365 days
Physical Properties
Viscosity
Viscosity
Viscosity is a measurement of a fluid’s resistance to flow.

Viscosity is commonly measured in centiPoise (cP). One cP is defined as
the viscosity of water and all other viscosities are derived from this base. MPa is another common unit with a 1:1 conversion to cP.

A product like honey would have a much higher viscosity -around 10,000 cPs-
compared to water. As a result, honey would flow much slower out of a tipped glass than
water would.

The viscosity of a material can be decreased with an increase in temperature in
order to better suit an application

Mechanical Properties
Hardness
Hardness
Hardness is a dimensionless quantity. There is no direct relationship between measurements in one scale and their equivalent in another scale or another hardness test.
Durometer (Shore A) 80
Elongation
Elongation
Elongation is the process of lengthening something.

It is a percentage that measures the initial, unstressed, length compared to the length of the material right before it breaks.

It is commonly referred to as Ultimate Elongation or Tensile Elongation at break.

Additional Information

Recommended UV Cure

Light Dose, Joule/cm2: 0.4 to 1.0

For thicknesses >2.0 mils, a longer wavelength bulb is required e.g. Fusion "D". UV measurements were made with an EIT radiometer.

 

How to use:

1. Mixing/Dilution

  • Product is ready for use but should be mixed thoroughly using a plastic spatula. (Syringe-packed material needs no mixing).
  • Mix smoothly from bottom of container , being careful not to whip air into the product.

2. Application

  • LOCTITE EDAG PF 021 E&C should be applied in a glob over the entire surface if small devices, or along the outside leads of large devices.
  • Its viscosity is designed to conform to the device and flow out over the substrate just prior to UV curing.
  • Dot dispensing equipment should be selected based on the exact application, i.e., device size and production speed.

3. Cleanup

  • Uncured resin may be cleaned with Isopropanol,
