Parker LORD Announces Chemlok® 3Stream Significantly Reduces Manufacturing Costs of HCR Bonded Parts

Parker LORD Announces Chemlok® 3Stream Significantly Reduces Manufacturing Costs of HCR Bonded Parts

New self-bonding properties of HCR additive eliminate need for adhesives and primers

CARY, N.C., November 22, 2021 - The Parker LORD Elastomer Process Materials Division of Parker Hannifin Corporation, the global leader in motion and control technologies, has announced its new Chemlok® 3Stream for use with high consistency silicone rubber (HCR). The adhesion additive technology reduces the time to bond parts by imparting self-bonding properties into standard HCR, making it ready to bond to most substrates. 

Using Chemlok® 3Stream with HCR optimizes the manufacturing process and provides significant labor cost savings. With this new solution it is no longer necessary to prime the substrate before overmolding or compression molding, which saves on plant floor space by eliminating the adhesive station and drying area normally used for application of a primer. A traditional application would require specialized spray equipment and ventilation to manage the volatile solvents (VOCs) associated with primers. Using Chemlok® 3Stream, a primer isn’t needed, so no VOCs are present. 

Chemlok® 3Stream is added during the milling process. It is a liquid additive and only 0.5–2.0 percent weight is needed. The result is an HCR that is able to self-bond to surfaces such as clean metals, various plastics such as polybutylene terephthalate (PBT), nylon, polycarbonate and many other substrates. 

Chemlok® 3Stream does not impact the mechanical properties of HCR. Ideal usage is in automotive and medical applications in parts such as engine mounts to vibration controls, washers, gaskets and thermoplastic grips for medical equipment.
