- 5-Step Self-curing Workflow
Step 1 - Sweep (Optional)
Establish clean surface area for protection - blow out dust, de-grease using STIRRI-SWEEPTM or an IPA cleaning solution. Cleaning the surface also helps to avoid bubbles.
Step 2 - Screen (Optional)
Tape/mask sensors, lenses, microphones, cavities, jacks and parts that would rather not be coated - not required if connectors can pierce through the coating to establish the link.
Step 3 - Sink/Spray/Spread/Spin
Dip into a bath preventing excessive evaporation, rotate manually or using an automated system. Adjust speed as necessary for cosmetic preference - higher speeds may lead to bubbling. Use QC-AidTM traceable coating to detect voided areas. Spray or brush onto surface or use drip and spin method to distribute the evenly the coating.
Step 4 - Dry(Optional)
HYDRACOAT dries in less than a minute and is safe to touch in only about 8 seconds. Fast-track curing in 60oC chamber for 10 minutes. Auto-cures at room temperature in 24h - no heating required.
Step 5 - Unscreen (Optional)
Remove tape and masks for a final look.
