AAC Block Adhesive / Fillers (Component C)
NEROVAK Fillers are solid additives blended into liquid Flexible hybrid epoxy resin and hardener mixtures to modify viscosity, control sag, adjust density, and improve mechanical or thermal performance. It’s solid, insoluble particulates or fibrous materials added to adhesive and sealant formulations to modify their mechanical, physical, and economic characteristics
Major Functions of Fillers in Adhesives
| Function Category | Effect on Adhesive Performance | |
| Shrinkage Control | Reduces volume shrinkage and internal stress during curing or solvent evaporation. | |
| Mechanical Reinforcement | Improves tensile strength, elastic modulus, shear strength, and crack propagation resistance. | |
| Viscosity & Flow Control (Rheology) | Prevents sagging or running on vertical surfaces by creating thixotropic (shear-thinning) properties. | |
| Thermal & Electrical Conductivity | Enables heat dissipation or electrical current flow through the bondline. | |
| Cost Optimization | Lowers the overall volume cost of the adhesive compound by bulk displacement. |
| Advantage Category | Specific Benefit | |
| Viscosity & Flow Control | Prevents sagging or running on vertical/overhead surfaces | |
| Mechanical Strength | Improves hardness, compressive strength, modulus, and wear resistance | |
| Reduced Shrinkage | Minimizes internal stress and dimensional change during cure | |
| Thermal Management | Elevates thermal conductivity or lowers thermal expansion | |
| Electrical Properties | Tailors electrical insulation or adds conductivity | |
| Flame Retardancy | Absorbs heat and releases water vapor to stifle combustion | |
| Machinability & Surface Finish | Makes cured epoxy easier to drill, sand, machine, or shape | |
| Weight & Cost Reduction | Lowers material density or cuts overall formulation cost |
