How to Use

Fill into transformers or high-voltage components after ensuring all parts are clean and dry. Remove air pockets while filling and maintain a sealed system to prevent moisture ingress. Always use the lowest effective volume that meets insulation and cooling needs. Store sealed in a cool, dry place to preserve dielectric strength.
