Yes, primerless threadlockers are available. These are advanced formulations of threadlocking adhesives that do not require a separate primer to achieve optimal adhesion and performance. Traditional threadlockers often need a primer to prepare the surface, especially on inactive metals like stainless steel, aluminum, or plated parts, which can be less reactive. Primerless threadlockers, however, are designed to work effectively on both active and inactive metals without the need for additional surface preparation.
The development of primerless threadlockers is a result of advancements in adhesive technology, allowing them to cure and adhere effectively in a wider range of conditions. They are typically anaerobic adhesives, meaning they cure in the absence of air and in the presence of metal ions. These threadlockers are convenient for applications where time and efficiency are critical, as they eliminate the extra step of applying a primer, thus speeding up the assembly process.
Primerless threadlockers are available in various strengths, from low to high, to suit different applications, whether temporary or permanent. They are used in industries such as automotive, aerospace, and manufacturing, where reliable fastening is crucial. These products provide excellent resistance to vibration, temperature variations, and chemical exposure, ensuring that fasteners remain secure under demanding conditions.
In summary, primerless threadlockers offer a more efficient and versatile solution for securing threaded fasteners, eliminating the need for a primer while maintaining strong adhesion and performance across a variety of materials and conditions.
