Uniform standard for thread-locking coatings
A recent Bachelor’s thesis explores the creation of a new DIN standard for thread-locking coatings. The aim is to define minimum requirements for chemical and mechanical properties to enhance product safety and simplify international trade.
Thread-locking coatings are widely used across various industries to prevent the unintended loosening of threaded joints. In her Bachelor’s thesis, Sabrina Teixeira Guedes, supervised by Prof Dr Markus Schackmann, examines which chemical and mechanical properties are crucial for ensuring consistent quality. Key factors include adhesion strength, chemical resistance and ageing resistance.
In the practical section, a test method was developed to systematically assess these properties. The findings will form the basis for drafting a new DIN standard that sets out the minimum requirements for thread-locking coatings.
Benefits for industry and trade
The planned standard aims to provide manufacturers and users with greater certainty while facilitating international trade. In the long term, this could increase product safety, reduce complaints and improve the comparability of products.
A standardised approach will help to avoid quality fluctuations — a key factor in safety-critical applications. This work therefore offers valuable input for future standardisation in the field of functional coatings.
