Ingredients
Ingredient
Percentage
Function
Corn Starch
50.0%
Acts as the primary natural polymer providing adhesive strength and structure
Polyvinyl Alcohol
30.0%
Enhances film-forming capabilities and water solubility, improving bond strength
Glycerol
10.0%
Acts as a plasticizer to increase flexibility and reduce brittleness
Citric Acid
5.0%
Serves as a crosslinking agent to improve the adhesive's water resistance
Water
5.0%
Serves as a solvent and processing aid for mixing other ingredients
Manufacturing Process
Gel Phase
Heat Water to 90°C and maintain temperature
Dissolve Corn Starch in heated Water with continuous stirring using a high-shear mixer
Quality control: Check viscosity, target 2000-3000 cps at 70°C
Polymer Phase
Slowly add Polyvinyl Alcohol to the gel with continuous stirring until fully dissolved
Maintain solution temperature at 80°C for consistent polymer integration
Quality control: Ensure homogeneity and absence of lumps
Additive Phase
Slowly add Glycerol and Citric Acid to the polymer mixture and mix at 80°C
Ensure uniform distribution and prevent overheating, monitor temperature closely
Quality control: Check pH should be 5.0 - 5.5, adjust with Citric Acid
Usage Instructions
Apply evenly on clean, dry surfaces; press pieces together firmly and allow to set for 30 minutes. Full cure time is 24 hours.
