Cab-O-Sil Filler 20# LB Bag

20LB BAG!!!

Cab-O-Sil is a extremely light powder used as a resin thickener it is ideal for vertical surfaces to avoid sags and run-off. It is recommended no more than 1/2 part filler to 1 part of resin.

SIPERNAT® 22 LS is often used as thickener and thixotrope for liquid systems, such as body repair adhesives, which are based mainly on polyester or epoxy resins.  Furthermore, SIPERNAT® 22 LS can be used successfully as thixotrope in polyacrylate sealants. Finally, SIPERNAT® 22 LS is used also as free flow and anti-caking agent in hotmelt powders and granulate.

Properties/ Suitability/Benefits:

• SIPERNAT 22® LS is a very fine particle silica with a high specific surface area of 175 m2/g. 
• SIPERNAT 22® LS should be used at concentrations for body repair adhesives between 4 – 6 wt.- percent. 
• Body filler putties with SIPERNAT® 22 LS display superior levelling and a pinhole free surface after sanding, for example no porosity, compared to other thixotropes. 
• In polyacrylate sealants, SIPERNAT® 22 LS should be used at concentrations of 3 – 6 wt.- percent. 
• As free flow and anti-caking agent, SIPERNAT® 22 LS should be used at a dosage of 0.2 – 0.5 wt.- percent silica. 
• As a starting point, the silica particle size used should be 1/8 to 1/10 of the powder. Thus, the processability and handling of adhesives powders and granulates are improved.
