Custom Mixing Solutions for Superior Bonding Performance

In the adhesives and sealants industry, achieving consistent product quality and process efficiency is critical. The way you mix polymers, fillers, plasticizers, tackifiers, and curing agents directly affects the mix's bond strength, viscosity, curing behavior, and shelf stability. Whether you're manufacturing pressure-sensitive adhesives, epoxy resins, or silicone sealants, using the right mixer can make a good product into a great one.
At Shar Systems, we specialize in designing custom mixing solutions, including multi-shaft mixers and high-viscosity dispersers, that handle the complex formulations and rheological challenges of the adhesives and sealants market.
The Importance of Mixing in Adhesive & Sealant Production
Mixing plays a crucial role in formulating adhesives and sealants that deliver consistent performance across a wide range of applications:
- Uniform dispersion of fillers and additives
- Thorough blending of base resins with curing agents
- Homogenization of multi-phase ingredients
- Air removal to ensure strength and appearance
- Precise temperature control for reactive chemistries
A poorly designed mixing system can result in:
- Incomplete curing or crosslinking
- Viscosity inconsistencies
- Weak or unreliable bond strength
- Shelf-life degradation due to trapped air or moisture
Common Challenges in Adhesives and Sealants Mixing
High Viscosity Materials
Many adhesive and sealant formulations are extremely viscous, requiring heavy-duty mixers with robust torque and horsepower capabilities.
Multi-Phase Blending
Formulations often involve liquid resins, solid fillers, and gaseous additives, all of which must be precisely integrated to avoid settling or separation.
Heat Management
Some curing agents or reactive resins are exothermic and highly sensitive to temperature, making thermal control a vital part of the mixing process.
Air Entrapment
Air bubbles introduced during mixing can lead to voids, poor adhesion, and inconsistent cure rates, especially in pressure-sensitive or structural adhesives.
Shar Systems' Key Mixer Types for Adhesives & Sealants Manufacturing
Multi-Shaft Mixers
Designed to process high-viscosity materials and maintain uniform shear throughout the batch, our multi-shaft mixers combine slow-speed anchors with high-speed dispersers.
| Benefits | Applications |
| Ideal for wide viscosity ranges and non-Newtonian fluids | Structural adhesives |
| Improved heat transfer and thorough agitation | High-solids sealants |
| Efficient integration of solids into liquids | Epoxy potting compounds |
| Customizable with jackets, vacuum lids, and control panels | Reactive silicone adhesives |
High-Speed Dispersers
High-shear dispersers are essential for wetting out fillers, dispersing pigments, and deagglomerating solids in lower-viscosity adhesive formulations.
| Benefits | Applications |
| Fast particle size reduction | Water-based adhesives |
| Scalable from lab to production | Pressure-sensitive adhesives (PSAs) |
| Effective for slurry or pre-mix stages | Acrylic emulsions |
