This paper introduces a new additive technology, Chemlok 3Stream (3S), to impart self-bonding properties to non-self-bonding LSRs. Chemlok 3S-902 additive is fed via a standard additive pump directly into the LSR feed stream, similar to colorant dosing. In doing so, OEMs and tiers can eliminate the application of primers and their associated VOC and save significant costs gained from utilizing standard LSR grades over more expensive self-bonders.
