TUW-1710 Electronic Coating

TUW-1710 Electronic Coating is a 10% solids fluoropolymer concentrate at 1.52 g/mL density with no flash point. It is the partner grade to TUW-1700: the 1700 is the 2% working solution, while the 1710 is the concentrate used to replace solids dragged out of a running dip or spray bath so that film thickness stays on target without dumping the whole tank.
A common mistake is buying the 1710 as a ready-to-use coating — the film then comes out too thick, hazy and slow to dry. TUW-1710 Electronic Coating should be dosed against the bath's solids or film thickness, little and often, checking thickness as you go. It also works as a base resin for custom formulations that need different hand-feel, adhesion or chemical resistance.

1. Bath replenishment — Restore solids and film thickness when a dip or spray bath drifts low after extended running.
2. Formulation base — High-solids base for blending with other fluoropolymers and additives to tune feel, adhesion or resistance.
3. Local build-up — Extra protection on seams, edges and connector areas that need a heavier coat.
4. Sampling and small batches — Mix different solids levels quickly to validate thickness and performance before fixing the process.

 

Measure the bath solids or film thickness first, then dose to close the gap — no more than 10% of bath volume per addition, mix and settle before running parts. Using the concentrate neat gives an over-thick film that hazes, cracks and dries incompletely.
The concentrate is more viscous than the working solution, so reseal containers after sampling or transfer to stop solvent loss shifting the solids. Same limits as the 1700: solution below 150 °C, dry film below 250 °C, humidity below 60%.
Timing matters more than the dose: top up when first-off thickness falls 15% below standard or measured solids drop 10% below set point, rather than adding by feel every day. Reseal TUW-1710 Electronic Coating after opening, log the date, and stop using it if it stratifies or clouds — a bad addition can spoil the whole bath.
