Croda Crodamide BR Wetting Agent – Frequently Asked Questions (FAQ)

Q1: What is the primary function of Crodamide BR in industrial formulations?

A: Crodamide BR is a non-ionic wetting agent designed to reduce surface tension and improve substrate wetting, particularly on low-energy surfaces such as polyolefins and fluoropolymers. It enhances dispersion stability and interfacial adhesion in aqueous systems without significantly affecting foam profile or viscosity.

Q2: Is Crodamide BR compatible with common water-based coatings and inks?

A: Yes — Crodamide BR exhibits broad compatibility with acrylic, styrene-acrylic, and polyurethane dispersions, as well as pigment preparations used in water-based industrial coatings, gravure, and flexographic inks. Its non-ionic nature minimizes sensitivity to electrolytes and pH fluctuations typical in these systems.

Q3: How should Crodamide BR be incorporated into a formulation?

A: It is typically added during the let-down or post-addition stage, either neat or pre-diluted in water or co-solvent. For optimal performance, it is recommended to add before high-shear dispersion of pigments or fillers to ensure uniform interfacial coverage. Dosage depends on formulation requirements but generally ranges from 0.1% to 2% by weight of total formulation.

Q4: Does Crodamide BR impact film formation or drying behavior?

A: Crodamide BR is volatile-free and non-migrating, so it remains in the dried film and does not interfere with coalescence or film integrity. It may slightly influence open time due to improved wetting, but this effect is formulation-dependent and generally mild.

Q5: Can Crodamide BR be used in food-contact compliant applications?

A: Crodamide BR is not specifically certified for direct food contact. While it is widely used in industrial and packaging inks where incidental contact may occur, formulators must conduct full regulatory assessment—including migration testing and compliance with applicable regional frameworks—before use in food-contact applications.
