LSR Self-Bonding Additive

Eliminate the need for expensive self-bonding LSRs, solvents, labor associated with the application of primers and long lead-time of self-bonding LSRs. Incorporate Chemlok 3Stream additive into your injection molding process by adding the additive via a standard third stream pump, similar to a colorant. Our teams have gone through extensive testing to achieve rubber tearing bonds. Our adhesion promoter for LSR is proven on many thermoplastics and clean metals.

Transform Regular LSR into Self-Bonding LSR

Chemlok 3Stream is a new adhesion additive technology disrupting the LSR industry by transforming regular LSR into self-bonding LSR, without the premium cost and lead time associated with self-bonding LSRs or the labor and volatile organic compounds associated with traditional primer/adhesive applications.

What is Liquid Silicone Rubber?

Liquid Silicone Rubber (LSR) is a high purity two-part platinum-cured elastomer that is typically used in an injection molding process to form a part requiring precise dimensions. Due to its heat resistance, low temperature flexibility, chemical resistance and biological inertness, LSR is used in applications that span across multiple industries, including: automotive, electronics, infant care, medical, general industrial and consumer goods.

How to Bond LSR to Clean Metals & Plastics?

Bonding LSR to plastics and clean metals with current technology on the market requires primers or special self-bonding LSRs. Both bonding methods have significant drawbacks. Primers require extra process steps and the management of volatile solvents, while self-bonding LSRs suffer from high price, short shelf life and limited availability. However, Chemlok 3Stream is a new disruptive technology available enabling regular LSR to become self-bonding LSR, making it the best choice for bonding clean metals and plastics. Chemlok 3Stream additive is proven to bond to these substrates without changing the physical properties of the LSR.
