Thermochromic Microcapsules25.0%Provide reversible color change in response to temperature fluctuations
Acrylic Binder30.0%Ensures adhesion and flexibility of thermochromic layer on textile substrates
Water40.0%Used as a solvent to dissolve and disperse components evenly
Wetting Agent2.0%Improves the wetting of the textile surface for uniform coating
Defoamer1.0%Suppresses foam formation during application for a smooth coating
pH Stabilizer2.0%Maintains the optimal pH of the formulation for stability

Manufacturing Process

Water Phase

  1. Heat Water (Aqua) to 40°C while stirring continuously.
  2. Add Acrylic Binder (Acrylic Copolymer) and dissolve completely.
  3. Incorporate Wetting Agent (Polysorbate 20) and Defoamer (Dimethicone) for a homogeneous solution.

Color Phase

  1. Cool mixture to 25°C before adding Thermochromic Microcapsules.
  2. Gently stir in microcapsules to prevent damage to the encapsulation.
  3. Adjust pH to 6.5 using Citric Acid for optimal stability.

Final Processing

  1. Conduct quality control check ensuring uniform distribution and absence of foam.
  2. Transfer the finished formulation into spray equipment with a fine nozzle.

Usage Instructions

Apply evenly onto textiles using a spray gun set at low pressure. Ensure coating is applied in a well-ventilated area. Allow to dry completely at room temperature for 24 hours before testing temperature-responsive color change.
