Biuged BGD 537 Abrasion Resistance Tester for Touch‑Screen Coatings

The Biuged BGD 537 Abrasion Resistance Tester is a precision instrument designed specifically for evaluating the dry abrasion resistance of hydrophobic and omniphobic coatings used on touch‑screen devices and intelligent electronic products. It was developed in response to the new international standard ASTM D8380‑21, which defines a method for assessing the durability of touch‑screen coatings against finger‑induced wear, dust, and micro‑scratching. The tester simulates the repeated rubbing and micro‑abrasion that touch‑screen coatings experience during everyday use. A steel‑wire brush or specified rubbing medium moves back and forth across the coated surface under controlled load, frequency, and stroke length.

The test continues for a preset number of cycles, after which the coating is evaluated for:

• Gloss loss

• Surface haze

• Visible wear or micro‑scratching

• Hydrophobic/omniphobic performance degradation

This method provides a quantitative measure of coating durability under realistic touch‑screen wear conditions.

Key Features

Designed for Touch‑Screen Coating Standards

Developed to meet the requirements of ASTM D8380‑21, the international test method for abrasion resistance of hydrophobic and omniphobic coatings on intelligent electronic products.

Precision Rubbing System

A controlled reciprocating mechanism ensures stable, repeatable abrasion:

• Rubbing distance: 30 mm ± 1 mm

• Rubbing frequency: 60 cycles/min ± 5 cycles/min

Standardized Abrasive Medium

Uses a 0000# steel‑wire brush as the rubbing medium, ensuring consistent and comparable abrasion performance across tests.

Controlled Load Application

The rubbing head applies a precise, standardized load of:

• 10 N ± 0.5 N

ensuring uniform abrasion pressure.

Programmable Rubbing Cycles

Operators can set rubbing cycles from 0 to 9,999, with automatic stop at the preset value for fully repeatable testing.

Compact, Laboratory‑Ready Design

A small footprint and robust construction make the BGD 537 suitable for R&D labs, QC departments, and touch‑screen coating manufacturers.
