- RTI Class B
Product Description
LINQSOL BCP-1504 is a blue or red, busbar epoxy coating powder. It applies at low voltage copper and alumina busbars (600V) with a coating thickness of 0.3~1mm. With its low pick up temperature, BCP-1504 builds up quickly at small busbars and performs excellent coating results. It brings high productivity with low pre-heat temperature and quick curing. Due to its fine-grind process, it can be used with both electrostatic spray and fluidized bed dipping.
Key Features:
- Comparable with DK15-0463
- Good adhesion to copper, alumina
- Low pick up temperature
- High powder build rate
- Both electrostatic spray and fluidized bed coating
Recommended coating Temperature:
- 150 – 180 °C. (200 °C x 15 min)

| 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. | 1.52 | ||||

| 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. | 35 V | ||||
| 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. | 1.0x10-15 Ohms⋅cm | ||||

| 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. | 100 °C | ||||
| 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 | V-0 | ||||

OBSERVATION
- Coating appearance: Smooth, no-dripping, great edge coverage
- Coating process: Quick build rate on thickness, low pick up temperature;
- Preheat temperature: 240°C preheat temperature with 1 dip reaches 0.5mm, which is thicker than 1 dip @200°C, but appears small-size sag. With multiple dips, the surface becomes smooth again.
DISCUSSION
BCP-1504 presents good coating results with preheat temperature 200°C. BCP-1504 has low pickup temperature and it is designed to coat on small size busbar with quick build rate.

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.
