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).
