OPTICA WIPES P4 / 4 inch x 4 inch (10cm x 10cm) / Cleanroom-Grade 100 % Polyester Knit Wipers / Qty 100 Bag

100% Polyester Knit | ISO Class 4–5 Cleanroom | Laser‑Sealed Edges

Why Choose P Series for Optical & Display Bonding:

• Non‑abrasive & low-lint — safe for coatings, glass, plastics, polarizers, OCA film surfaces. Engineered to prevent fiber transfer or scratches. Accurate for optics, optical filters, and TFT/LCD backlight components.
• Laundered in ultra-pure DI water within ISO Class 4–5 (Class 10–100) cleanroom facility. Each wipe is sealed and packed under Class 100 conditions to minimize particles, ions, and non-volatile residues. Built to meet IEST‑RP‑CC‑004.3 standards. 
• High absorbency + chemical resistance — and compatible with isopropyl alcohol, ethanol, acetone and other common solvents. Ideal for applying primer layers or vapor cleaning during optical bonding prep.
• Chemical compatibility for primer and adhesives — polyester does not shed silicon-based contaminants and is inert to most silicone and epoxy primers used in LOCA (liquid optically clear adhesive) processes.
• Trusted by optics industry leaders — e.g., Thorlabs recommends “a soft, dust‑free cloth (such as Optica P Series Premium Optical Cleaning Pads) and isopropyl alcohol” for substrate prep before OCA lamination. OP Series replicates this level of cleanliness and material softness.

Optica Wipes P Series delivers quality PPE level of cleanliness and consistency demanded in optical bonding environments. When glass substrates, polarizers, or backlight films must be prepped for OCA lamination, the OP Series offers the soft, low-lint, solvent-compatible performance required to maximize yield and image clarity in your critical assembly stages.
