GCP 1805 | Halogen-free version of DK18-05 Insulating Epoxy Coating Powder

Main features

Blue and Gold Colors
Halogen-free Epoxy Coating Powder
For class 2 & 3 capacitors and varistors

Product Description

LINQSOL™ GCP1805 is an insulating epoxy coating powder for capacitors, varistors and other passive components. It was designed specifically as a halogen-free version of DK18-05 with similar technical specifications, just without containing any of the halogens.

LINQSOL GCP-1805 epoxy coating powders can be applied through a fluidized bed with temperatures as low as 105°C.

LINQSOL™ GCP1805 can be used for most class 2 & 3 ceramic capacitors and varistors. Its excellent curing conditions make the epoxy coating powder also very suitable for tantalum capacitors and other temperature-sensitive devices.

LINQSOL™ GCP1805 epoxy coating powders are laser markable and are rated with a UL 94 V-0 flammability and RTI rating of 130°C.

Used for insulation & coating of:

Class 2 & 3 ceramic capacitors and varistors
Tantalum capacitors
Resistors
Passive components
Temperature sensitive devices

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.

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 @ 15°C	12 months

Thermal Properties

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.

UL 94 Rating

UL 94 Rating
Flammability rating classification.
It determines how fast a material burns or extinguishes once it is ignited.

HB: slow burning on a horizontal specimen; burning rate less than 76 mm/min for thickness less than 3 mm or burning stops before 100 mm
V-2: burning stops within 30 seconds on a vertical specimen; drips of flaming particles are allowed.
V-1: burning stops within 30 seconds on a vertical specimen; drips of particles allowed as long as they are not inflamed.
V-0: burning stops within 10 seconds on a vertical specimen; drips of particles allowed as long as they are not inflamed.
5VB: burning stops within 60 seconds on a vertical specimen; no drips allowed; plaque specimens may develop a hole.
5VA: burning stops within 60 seconds on a vertical specimen; no drips allowed; plaque specimens may not develop a hole

Additional Information

The following table shows the comparison of GCP1805 compared to DK18-05.

alt

It could be seen from the table that the properties of GCP1805 are quite similar to DK18-05. The important features are the optimized pickup temperature and the low cure temperatures as low as 110°C. GCP1805 is expected to have a similar coating performance as DK18-05. It is suggested to coat GCP1805 powder for your passive components under the same preheating and curing conditions for DK18-05. Based on the trial results, the coating process could be further adjusted and optimized.
