Frequently Asked Question

Electrophortic lacquers, also known as 'e-coats', are used in industrial coatings. Here's a breakdown of their components and typical preparation ratios, keeping in mind that specific formulas vary based on desired properties:
Components:

Resin: Often epoxy or acrylic polymers. These form the film's backbone.
Pigments: Colorants and additives like titanium dioxide for whiteness.
Solvent: A volatile liquid like water or an alcohol, allowing for film formation.
Catalysts: Chemicals to initiate crosslinking reactions, hardening the coating.
Additives: These can be for flow control, corrosion resistance, or other desired characteristics.
Preparation Ratio:

Resin: Typically 15-25% by weight of the total formulation.
Pigments: 5-15% by weight, depending on the desired color and opacity.
Solvent: The remainder of the formulation (60-80% by weight), accounting for most of the volume.
Catalysts & Additives: Small amounts (Laboratory Preparation:
1. Precise Weighing: Use an analytical balance for accurate measurements of all components.
2. Solvent Mixing: Mix the solvent and resin components first, ensuring thorough dissolution.
3. Pigment Dispersion: Carefully disperse the pigments in the resin solution using a high-shear mixer to avoid settling.
4. Catalyst Addition: Add the catalyst(s) last and mix gently to avoid premature curing.
5. Filtration: Filter the final mixture through a fine mesh to remove any particulate matter.
Note: Exact ratios, specific chemicals, and detailed procedures can vary significantly based on the desired end-use properties of the e-coat, manufacturing requirements, and safety considerations.
