4731 is a quick drying, low viscosity, alcohol-based stamping ink with very low percentage of binding agent. It was developed especially for micrometering and spraying systems to avoid clogging the fine nozzles.
It provides colour intensive imprints, however is not very colour fast or resistant to solvents.
We recommend 4731 stamping ink for rubber goods such as one-way latex gloves and bicycle inner tubes not requiring extremely high resistance.
