Scratch Scuff Mar Finish Tester
Category：Interior Material Tester
Introduction
The Scratch Scuff Mar Finish Tester is designed to evaluate the scratch, scuff, and mar resistance of materials such as automotive paints, coatings, plastics, and decorative finishes. It simulates mechanical contact and friction under controlled conditions, providing quantitative and qualitative assessment of surface durability and appearance retention. This tester complies with automotive standards, including General Motors GM-9150P, to ensure materials meet required performance levels.
Application
You can use this tester to:
Evaluate automotive interior and exterior coatings, paints, and functional surface treatments for scratch and scuff resistance.
Test plastics, sprayed coatings, and decorative panels for surface durability.
Conduct comparative assessment of surface appearance retention and mechanical damage resistance.
Support material selection, R&D validation, and quality control in the automotive and manufacturing industries.
Assess anti-scratch, anti-scuff, and surface integrity performance of materials under simulated real-world use.
Standards
This tester is suitable for testing according to:
(1) GM 9150P – Scratch and scuff resistance for automotive materials
(2) GMW14130 – Surface abrasion and scuff resistance
(3) ISO 1518 – Paints and varnishes—Scratch resistance methods (reference)
(4) ASTM D7027 – Coatings and finishes surface abrasion and scuff evaluation (reference)
(5) SAE J400 – Automotive material surface durability evaluation (reference)

FAQ
1.What is this product?
It is a scratch, scuff, and mar finish tester used to assess surface durability of coatings, paints, and decorative materials under mechanical contact.
2.What is this product used for?
You use it to determine how well materials resist scratches, scuffs, and surface damage, particularly for automotive or decorative applications.
3.How does this product work?
The sample is fixed on a test platform, and a weighted paperclip drags along the surface under constant load. All four edges of the sample are tested, and visual evaluation determines surface damage.
4.Why is this product important?
It ensures material surfaces retain appearance and quality under real-world wear, supporting material selection, quality control, and product reliability.
5.Which industries is this product suitable for?
Automotive, coatings, plastics, decorative finishes, material R&D, and quality assurance laboratories.
