Problems IBIB Solves

Why formulators add IBIB to their coating systems

Blushing / Whitening

Cause: Moisture absorption during film formation in humid conditions

Why buyers consider IBIB: Its low water solubility (1 g/L at 20°C) makes it relevant for moisture-sensitive coating systems where reduced blushing risk is important.

Substrate Burning on Plastics

Cause: Aggressive solvents (xylene, toluene) attack PC/ABS substrates

Why buyers consider IBIB: In some plastic coating formulations, IBIB may be evaluated as part of the solvent blend where lower substrate attack risk is desired. Typical reference addition is around 10–12% of the solvent package.

Metallic Pigment Oxidation

Cause: Moisture reacts with aluminum/metallic flakes causing darkening

Why buyers consider IBIB: Low water solubility can make IBIB relevant in metallic coating systems where buyers want to reduce moisture-related appearance risk during formulation evaluation.

Electrostatic Spray Efficiency

Cause: Low-resistivity solvents reduce charge transfer to paint particles

Why buyers consider IBIB: High electrical resistivity makes IBIB a candidate for evaluation in electrostatic spray formulations where resistivity tuning matters.
