Carbosil
CARBOSIL Resin Viscosifier
Carbosil or known as Aerosil is Viscosifying Fumed Silica, Resin Thickener or Rheology Modifier used to thicken epoxy resin to achieve a smooth, non-sagging, high-strength mixture for coating, structural bonding, filleting and filling. CARBOSIL is engineered to provide ideal thickening properties with added thixotropic and sheer thinning properties to make it easy to trowel, screed and apply to any surface.
Carbosil fumed silica is widely used to provide thickening and enhance anti-settling properties in resin, flow and gel coats. Can be used for reinforcement and gluing/adhesive applications. The product offers an excellent balance of thickening efficiency and dispersibility.

Application
Use any of SHIMICOAT Clear Epoxy Resins, mix at correct ratios and add Carbosil to your desired viscosity. Mix for 2-3 minutes and apply to your surface within curing time-frame of Epoxy product used.
For example, if using Ultra Clear Epoxy, add 1.0Lt of Part B (Curing Agent) into 2.0Lt of Part A (Resin), mix for 2-3minutes and add your desired quantity of CARBOSIL. Use EpoDil “Epoxy Diluent & Thinner” to wipe and clean your tools and finish surfaces.
Preparations
Clean and dry surface. Ensure surface to be coated is free of all dirt, grease, oil, paint, curing agents and other contaminants. Removal of Oil Contamination by degreaser and alkaline cleaning pressure wash.
Acid-wash to enhanced surface porosity and etch the surface.
Ensure moisture free surface. Allow to completely dry, run Dry Test. Place a piece of plastic over a small area, tape the edges and leave for 1 hour. Remove plastic, if there is no moisture on either surface, concrete is sufficiently dry.
Ideally, always consider surface grinding and removal of loose materials. Grinding is always advisable prior to application of all Shimicoat Epoxy products, to maximize adhesion. For further information, please refer to SHIMICOAT Instruction for “Surface Preparations”.
The product can be used as filler materials with any of SHIMICOAT Epoxy products (Clear or Tinted) to form an easy flow and easy apply epoxy mortar, ideally suitable for crack and hole repair prior to coating. CARBOSIL Epoxy paste is non-sagging, engineered for high strength for both horizontal and vertical applications.
