KF-6050 is a single-component solvent-based LSR silicone primer & silicone adhesion promoter independently developed by INNOSILICONE with 20+ years silicone manufacturing experience. Formulated exclusively for liquid silicone rubber overmolding, this silicone primer greatly improves adhesive performance between LSR and PC, PBT, PA, aluminum, stainless steel after substrate corona treatment, which makes it the ideal corona treated LSR primer for global manufacturers.

As a widely used silicone rubber priming coating in the industry, our KF-6050 silicone adhesion agent supports spray and dip coating for mass production of auto, electronic and medical overmolded parts. No extra mixing required, fast room temperature drying helps clients cut down production cost for LSR overmolding projects.
