BPC6020 Voice Coil Winding Adhesive
BPC6020 voice coil winding adhesive, is a type of adhesive known as butyral phenolic cement, is designed for applying on the wire winding of the voice coil in speakers. This adhesive undergoes a two-stage curing process. Initially, coat it onto the wire and dry it to a B-stage, making it tacky and partially solid. This stage allows for easier handling and assembly of the voice coil before final curing. After reaching the B-stage, heat it again to harden into the thermoset stage.
BPC6020 has a viscosity range of 2,500-3,500 cps. If the adhesive is too thick, you can add methyl ethyl ketone (MEK) to thin it out, ensuring ease of application and optimal performance.
APPLICATION:
Apply by roller or brush for best results. Make sure to apply a thin coat to the windings of the wire.
After air drying the coil until it is dry to the touch, place it in the oven and dry at 250 degrees Fahrenheit for 2 minutes. Remove the parts and allow them to cool. Then, post cure in the oven for 30-40 minutes at 325 degrees Fahrenheit to achieve maximum heat resistance in the second stage. . After the initial drying stage, you can re-activate the adhesive with MEK.
STORAGE AND HANDLING:
The shelf life is at least 6 months. For optimum shelf life of this product, store at temperatures of 60-80 F. Lower temperatures will cause increased viscosity of a temporary nature, whereas higher temperatures may have a permanent effect on viscosity.
WARNING: FLAMMABLE
Will Burn when exposed to spark or any flame source. Use only in a well ventilated area during application and until vapors subside.
