Application: Resins – Mixing, Reacting & Finishing with Precision by PerMix

Introduction

Resin manufacturing blends chemistry with mechanical precision. Whether creating synthetic polymers, epoxy systems, alkyds, or acrylic emulsions, resin processors face a daily balancing act: viscosity management, heat control, solvent handling, and batch uniformity.

PerMix designs and engineers complete resin mixing and reaction systems that deliver predictable quality across every step — from polymerization to dilution and finishing — with the flexibility to handle viscous melts, solvent-based blends, and waterborne formulations.


The World of Resins

Thermoset vs. Thermoplastic Resins

  • Thermosets (epoxies, phenolics, alkyds) require precise temperature and catalyst control during polymerization. Once cured, they can’t be re-melted — so the initial reaction step is critical.
  • Thermoplastics (PVC, polyolefins, acrylics) are physically blended or modified without irreversible chemical curing, but demand uniform heat and mixing for consistency.

Resin Types by Industry

  • Paints & Coatings: Acrylics, alkyds, and polyesters.
  • Adhesives & Sealants: Epoxies, polyurethanes, silicones.
  • Composites: Polyester and epoxy matrices for carbon or glass fiber reinforcement.
  • Electrical & Electronics: Encapsulation resins with precise dielectric properties.

Every formulation has a unique viscosity curve, solid content, and exotherm profile — and PerMix mixers are designed to handle them all.


Process Overview: From Reaction to Finishing

1. Polymerization / Condensation Reaction

High-temperature reactions demand heat transfer efficiency, vacuum or pressure capability, and proper agitation to avoid localized overheating or incomplete polymerization.

PerMix Solution:

  • Reactors and Vacuum Multi-Shaft Mixers equipped with anchor, turbine, and disperser combinations for efficient mass transfer.
  • Jacketed heating/cooling systems with precise temperature control up to 350°C.
  • Optional vacuum systems for moisture removal or condensation control.
  • Load cells & PLC/HMI control for automated dosing and monitoring.

2. Blending & Additive Incorporation

Once the base resin is synthesized, additives such as plasticizers, pigments, stabilizers, or crosslinkers are mixed in to achieve final properties.
Challenges: High viscosities, immiscible phases, and temperature-sensitive components.

3. Solvent Dilution & Deaeration

In many coating or adhesive applications, the base resin is diluted with solvents or reactive monomers. Entrained air and moisture can cause foaming and incomplete cure.

PerMix Solution:

  • Vertical Vacuum Ribbon Mixers for solvent blending and moisture removal under vacuum.
  • Vacuum Double Planetary Mixers with condensate recovery for volatile control.
  • Explosion-Proof (ExP / ATEX) configurations for flammable solvent systems.
  • Integrated solvent condensation and recovery systems for safe, eco-friendly operation.

4. Finishing & Quality Control

Final steps include viscosity adjustment, color correction, filtration, and packaging. Every batch must meet reproducibility and stability standards.

PerMix Solution:

  • Vacuum Ribbon Mixers / Dryers for precise viscosity tuning and drying of prepolymer or solid resin pellets.
  • Load-cell-mounted batch systems with recipe automation and data logging.
  • Hygienic design options for water-based emulsions.
