In recent years, with the widespread application of silicone materials in the fields of construction, automobiles, electronics, etc., the selection and performance optimization of crosslinkers have become the focus of formulation engineers. A new type of vinyl mixed ketoxime crosslinker has gradually become a hot spot in the market due to its excellent room temperature curing efficiency and low by-product release.
Compared with the traditional single ketoxime crosslinker, this type of mixed crosslinker introduced by the vinyl structure has a higher crosslinking reaction rate and can quickly form a film in a humid environment, shortening the construction waiting time. More importantly, it gives the cured product better flexibility and stronger substrate adhesion, and is suitable for a variety of substrates such as metal, glass, and ceramics.
In the context of increasingly stringent environmental regulations, this type of crosslinker has become an ideal choice to replace traditional crosslinkers with its low VOC emissions and low odor characteristics, providing a solution that emphasizes both performance and environmental protection for products such as sealants and structural adhesives.
