Manufacturing Process

Water Phase

  1. Heat water to 60°C and maintain temperature.
  2. Stir using a high-shear mixer for even distribution of ingredients.

Protein Dispersion Phase

  1. Gradually add soy protein isolate while maintaining constant stirring.
  2. Ensure full dispersion by mixing for at least 30 minutes.

Final Processing

  1. Add plant-based resin and mix at moderate speed for 20 minutes.
  2. Incorporate natural preservative and plasticizer, mix until homogeneous.
  3. Perform quality control tests for viscosity and adhesive strength.

Usage Instructions

Apply a thin, even layer to the wood surface. Press firmly with a clamp or similar tool for at least 30 minutes. Ideal application thickness is 0.1 mm for optimal results.
