Upgrade of Loctite Instant Adhesives, Activators & Primers in 2021

Henkel Loctite have notified us of their intention to upgrade the formulations of a small number of cyanoacrylate (instant) adhesives, activators and primers during 2021. These changes are part of Henkel’s commitment to continuous improvement, and focused on health and safety benefits for the end customer. 

The above listed cyanoacrylate adhesives will be formulated without adding Hydroquinone (HQ). In addition, Loctite 454, Loctite 3090 and Loctite 3092 will also be formulated without adding 2,2'-Methylenebis(4-methyl-6-tert-butylphenol) (MMBP). These raw materials function as shelf-life stabilizers and represent a small percentage of the products’ overall formulations.   

Significant investment has been made in reformulating these products with more globally acceptable raw materials, and the formulation upgrades have been thoroughly tested by Henkel. The performance properties and shelf lives of the products remain consistent with existing Henkel Quality Specifications.   

The new formulations will be implemented on a running basis with no changes to the product names, part numbers, or Technical Data Sheets (TDS). 

In addition to the changes to the previously mentioned adhesives, Henkel are also upgrading the formulations of the above primers and activators with more globally acceptable raw materials. Again, the performance properties and shelf lives of the products remain consistent with existing Henkel Quality Specifications.  

As this change affects a significant proportion of the formulation, new labelling will be required. New Safety Data Sheets (SDS) will also be made available and Technical Data Sheets (TDS) will be updated once all of the related testing is completed.
