Aqueous polymer barrier coatings: BASFRecent Research Landscape

Permeability in paper and packaging substrates leads to product spoilage and structural failure. This lever engineers the polymer density and crosslinking within water-based dispersions to block moisture transport.

What technical problems is BASF addressing in Aqueous polymer barrier coatings?

Insufficient coating storage stability

(9)evidences

Aqueous resin dispersions often suffer from sensitivity to moisture and premature degradation when exposed to water. Improving the durability of the final film against aqueous environments prevents coating failure and structural instability.

Inadequate substrate adhesion

(7)evidences

Manual or static mixing of functionalized aqueous binders often leads to non-uniform chemical distribution. Achieving precise stoichiometric ratios and dispersion stability ensures predictable curing and coating integrity.

Insufficient substrate gas impermeability

(6)evidences

Standard packaging materials suffer from high gas and moisture transmission rates. Reducing these rates prevents product spoilage and extends shelf life.

Poor ink substrate adhesion

(4)evidences

Inadequate bonding between aqueous binders and substrates leads to mechanical failure and ink delamination. Improving interfacial integrity ensures durability in high-moisture environments.

Silicate coating viscosity instability

(4)evidences

Poor dispersion of titanium dioxide leads to flocculation and inconsistent opacity in aqueous systems. Achieving uniform particle distribution prevents sedimentation and ensures optical performance in automotive and pharmaceutical coatings.
