Chemlok 6451 Adhesive
High-Temperature Adhesive for NBR and HNBR to Metal Bonding
Chemlok 6451 is a high-temperature adhesive designed to create strong bonds between NBR and HNBR elastomers and metal substrates. It's versatile enough to be used as a single-coat adhesive or as part of a two-coat system with Chemlok 207 primer for enhanced performance in demanding environments. The resulting bonds exhibit excellent tear strength and resistance to various chemicals and environmental conditions frequently encountered in downhole applications.
