{"product_id":"coil-varnish-air-dry-8-oz-tin","title":"Coil Varnish — Air-Dry, 8 oz Tin","description":"\u003cp\u003eAfter you rewind a coil you need to lock the turns in place so vibration does not chafe the enamel off and create a short. Old shops dipped, baked, and pressure-impregnated. You probably do not have a vacuum chamber in your garage. This is the brush-on air-dry version that works when you are doing a one-off rewind and the customer needs the motor back by the weekend.\u003c\/p\u003e\u003ch2\u003eSpecifications\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eVolume:\u003c\/strong\u003e 8 fl oz \/ 237 ml\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e Modified alkyd, air-dry\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDielectric strength:\u003c\/strong\u003e 1,400 V\/mil after 72 hr cure\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCure time:\u003c\/strong\u003e Tack-free 2 hr, full cure 72 hr at 70°F\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoverage:\u003c\/strong\u003e Roughly one small motor stator per tin\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCleanup:\u003c\/strong\u003e Mineral spirits\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eHow to use it\u003c\/h2\u003e\u003cp\u003eTwo thin coats beats one thick coat every time. Thin coats penetrate between turns and cure without skinning over before the solvent escapes. A thick coat skins on the outside and stays soft underneath — which defeats the purpose. Brush on the first coat, let it go tack-free (about two hours at room temperature), then brush the second. Full mechanical and dielectric strength at 72 hours.\u003c\/p\u003e\u003ch2\u003eWhat it does and doesn't do\u003c\/h2\u003e\u003cp\u003eAir-dry varnish locks turns, seals out moisture, and provides a dielectric barrier between adjacent conductors. It does not replace vacuum pressure impregnation for motors that run hot, wet, or under continuous heavy load. For a bench grinder, a small lathe motor, a vintage fan, or a hobby transformer — it is the right tool. For a pump motor running submerged or a compressor motor cycling all day, talk to a rewind shop with a dip tank.\u003c\/p\u003e\u003ch2\u003eShipping note\u003c\/h2\u003e\u003cp\u003eShips with ORM-D label via USPS Ground.
