Hard Coated Polycarbonate Sheet

Abrasion-resistant surface for panels that get cleaned, touched and handled every day.

The one genuine weakness of polycarbonate is surface hardness. Bare PC marks under a gritty cloth, and after a year of daily cleaning a clear panel looks hazy. Hard coating fixes it: a cured surface layer that resists abrasion and most cleaning chemicals while the sheet underneath keeps its full impact strength.

This has to be specified up front. A coating cannot be applied to sheet you already own, and it is the single most common regret we hear from buyers who ordered plain sheet for a high-traffic application.

Specification

Impact strength	Unchanged — full polycarbonate performance retained
Chemical resistance	Improved against common cleaning agents
Thickness	1 mm – 12 mm
Widths	1220 / 1560 / 1820 / 2100 mm (other widths made to order)
Combinable with	UV protection, anti-fog, tinted and frosted finishes

When a hard coat earns its cost, and one face or both

Uncoated polycarbonate is tough but soft-surfaced: it scratches under cleaning, handling and airborne grit. A hard coat is an abrasion-resistant surface layer that keeps the panel clear where standard sheet would haze over. It does not change the impact strength — the polycarbonate underneath is unchanged — it protects the appearance and the light transmission over the panel’s life.

Situation	Specify
Panel cleaned or wiped daily (guards, screens, displays)	Hard coat on the exposed face
Both faces handled or cleaned (partitions, machine windows)	Hard coat both faces
Outdoor and cleaned (signage, canopies, glazing)	Hard coat plus UV co-extrusion
Occasional handling, appearance not critical	Standard polycarbonate — the coat is not worth the cost

The hard coat also improves resistance to common cleaning agents, which is why it is specified where a panel meets solvents or frequent disinfection. It can be combined with UV protection, anti-fog and tinting on the same sheet — state the faces and the finishes together so they are built in one pass, not retro-fitted. Where scratch resistance matters more than impact, compare with acrylic (PMMA), which is harder-surfaced but brittle.

Typical applications

Retail display and point-of-sale fixtures
Bus shelter and station glazing
Machine windows in dusty environments
Public-facing screens and counters
Vehicle and equipment glazing

Questions buyers ask

How much harder is it than plain polycarbonate?

Enough that routine cleaning stops leaving visible swirl marks, which is the practical test that matters. It does not reach the surface hardness of glass, and no coated plastic does.

Can I coat one side only?

Yes, and it is common — the exposed face is coated and the interior face left plain. Specify which face when you order, because the sheet is not symmetrical afterwards.

Does the coating affect optical clarity?

No measurable loss on clear grades. It is applied thin enough that light transmission is effectively unchanged.

How to compare abrasion-resistant polycarbonate

A statement such as “scratch resistant” is incomplete without the test method, specimen preparation, coating face and acceptance criterion. When comparing samples, request the same test basis and confirm whether the report covers the grade and thickness being quoted.

Item to confirm	Procurement question
Test method	Which abrasion or coating test was used, and what result is reported?
Coated surface	Is one face or both faces coated, and how is the protected face identified?
Chemical contact	Which cleaner, coolant or sanitizer will touch the panel?
Fabrication	Will the part be cut, drilled, printed, bent or formed after coating?
Evidence scope	Does the document identify supplier, grade, thickness and specimen?

Drawing and sample review

Send the finished drawing and identify visible zones, critical edges, holes and any area that must remain optically clear. A coated sample can be reviewed with the intended cleaner and handling method before production. Coating improves surface durability but does not remove the need for compatible cleaning and correct installation.

Submit the application, test requirement and drawing through the hard-coated sheet RFQ route.
