Liquid Optical Clear Adhesive Bonding (LOCA): Mastering the Process
The Definitive Guide to Liquid Optical Clear Adhesive Bonding (LOCA)
Liquid Optical Clear Adhesive, or LOCA, remains one of the most effective ways to refurbish high-end mobile displays. Liquid optical clear adhesive bonding provides exceptional clarity and contrast because the liquid fills every microscopic imperfection on the glass surface. Jiutu Technology provides the industry's most reliable equipment for executing liquid optical clear adhesive bonding, ensuring that your shop can deliver factory-spec repairs for iPhone, Samsung, and beyond.
Why Liquid Optical Clear Adhesive Bonding is the Professional Choice
While OCA tape is popular for retail shops, liquid optical clear adhesive bonding is often preferred for high-end "Edge" or curved displays. The liquid nature of the adhesive allows it to flow naturally into the curves of a Samsung S23 Ultra or iPhone 15 Pro, eliminating the risk of delamination at the edges. Jiutu's liquid optical clear adhesive bonding machines feature programmable dispensing arms that ensure the perfect volume of glue every time.

Repair Pro FAQ
Q: Does liquid optical clear adhesive bonding cause backlight bleed?
A: Only if too much pressure is applied. Our machines use a "zero-pressure" gravity-feed method for the initial bond.
Q: How do I clean excess LOCA?
A: We recommend using high-purity IPA and our specialized UV-pre-curing process for easy cleanup.
Q: What is the benefit over OCA tape?
A: Better optical transmittance and superior results on curved displays.
