Addition level(m/m %) is 10~50.

In RTV Elastomer and Adhesive

Effect:Fumed silica is used as thickening, thixotropic and reinforcement agents in RTV rubber and adhesive.
Recommended model: HL-150，HL-200，HB-151，HB-152，HB-615，HB-139，HB-135.
Addition level(m/m %) is 3~20.

In coating, paint and ink

Effect:Fumed silica can be preferably dispersed in a polar system, act as anti-settling, thixotropic and anti-sagging agents.
Recommended model: HL-150，HL-200，HL-300；HB-151，HB-152，HB-615，HB-620，HB-630，HB-139.
