Scratching, Abrasion and Mar

Outside appearance is directly associated with product quality. Decoratively finished workpieces should therefore look like new for as long as possible. This places a large number of demands on the coating: among other things, it must offer protection against abrasion and marring (=loss of material due to friction) and should have increased resistance to scratching (= forces exerted by sharp objects).

Superior Scratch and Abrasion Resistance

Formulated with advanced resin systems and optimized additives, anti-scratch powder coatings create a tough and resilient surface that significantly reduces visible scratch marks caused by friction, impact, or repeated use. Compared with conventional powder coatings, this type of coating offers improved hardness and surface recovery, helping products maintain a clean and premium appearance over time.

Durable Protection for Demanding Applications

Anti-scratch powder coatings are suitable for a wide range of applications, including furniture, office equipment, metal desks, cabinets, doors, frames, enclosures, and electronic housings. They are particularly effective for surfaces that are prone to wear, such as shelves, panels, public facilities, and high-touch components. The coating provides reliable protection without compromising flexibility or adhesion.

Aesthetic Flexibility

Available in various gloss levels, including matte, satin, and high gloss finishes, anti-scratch powder coatings can be matched to standard RAL colors or customized color requirements. The coating delivers a smooth and uniform surface appearance while maintaining its scratch-resistant properties, making it suitable for both functional and decorative uses.

Application:

· Pipeline industry: anti-corrosion pipeline, oil pipeline, sewage pipe, vessel water pipe, gas pipe and valves etc.

· Metal furniture: Steel furniture, documents cabinets etc.

· Kitchen utensils: gas cylinder, gas cooker, kitchen ventilator etc.

· Construction industry: door lock, rebar and steel plate.

· Electrical industry: Electronic spare parts, winding coil, and insulation coating of the rotator etc.

For its convenient application,high intensity, easy to clean and anti-impact performance etc, our product can be applied to steel coils and pre coating plate, for example, plant, house building precast piece, roof, wall,retail booth,container,isolated column,counter and door frame etc.

Which industries are particularly affected?

Architecture

Coated architectural components such as facade panels and window frames can be affected by scratching and abrasion even before installation. Mechanical stresses act on the components already as they pass through production – a clear risk to their later appearance. Once in use, scratching can occur, especially during cleaning. To prevent this, we recommend to always follow our General Cleaning Recommendations.

Furniture production

A piece of furniture is used every day – just as daily, it is moved, stacked on top of other furniture and/or contaminated by substances that chemically attack the surface. This results in a significantly increased susceptibility to damage.

Other outside applications

The already mentioned stresses to some extent apply to every piece of equipment, that is placed outdoors and/or in public areas. Public kiosks are a prime example for this, most often found in restaurants, malls and in the streets.

FAQs：

What is the difference between Mar and Abrasion?

Abrasion refers to the wear and tear of friction caused by mechanical parts and instances of repetitive scraping or rubbing, while Mar is described as physical deformations or markings that do not break through the surface. This includes gloss and shade differences.

How is scratch resistance tested?

In a laboratory environment the Martindale Test is very commonly used. Here a coated panel is rubbed against a surface at a specified force for a certain time period. Afterwards the results in e.g. gloss retention are compared.

Other common testing methods could be the Pencil Hardness Test (EN ISO 15184:2020), the Buchholz Indentation Test (EN ISO 2815:2003) or using a Manual Clemen Unit (EN ISO 1518:2019)

How is mar resistance tested?

performs the following 3 lab tests:

​​​​​​​1. Panel rub test:

Starts by performing 50 double rubs of 2 coated panels (same material), then a visual assessment is conducted.

2. Crock meter test:

Another lab test for mar resistance, commonly used in the automotive industry. Results are expressed as visual assessment or color / gloss retention after the surface is marred with crocking cloth or abrasive paper.

3. Scrub tester:

Also used in automotive industry this test is simulating car wash resistance. A coated panel is scrubbed with nylon bristle brush until failure occurs. Results are measured by the number of cycles until failure or measurement of color and gloss after 100 cycles. Scrub resistance is visually checked after 5,000 scrubs.

In the field the quickest way of testing for mar resistance is a simple coin mar test.

Can scratches in powder coating be repaired?

There are two ways of fixing a scratch in a powder coating. The choice depends on the severity of the damage:

surface scratches: here, the surface is pretreated with a polishing agent and then sealed with another special agent. It should be noted here that this type of treatment can influence the gloss level of the surface.

deep scratches: if scratches reach down to the substrate, the defect is usually repaired with wet paint. Coaters must pay special attention to matching the paint to reduce later inconsistencies in color and gloss level.
