Product Description
Waterborne Styrene-Acrylic Emulsion for DTM Anti-Corrosion Coatings
WL-Z412 is a styrene-acrylic copolymer emulsion for waterborne industrial paints, characterized by small particle size and moderate viscosity. It exhibits good compatibility with rust inhibitors and anticorrosive pigments, and the products formulated with it offer excellent water resistance, brine resistance, and salt spray resistance. It contains no heavy metals or halogens and is suitable for use as all-in-one primer-topcoat paints.
Introduction
In formulation design, based on its characteristics of small particle size and weak alkalinity, the following recommendations are made:
- Coalescing agents: Given its MFFT of approximately 20°C, the dosage of coalescing agents (such as Texanol) should be appropriately adjusted during winter construction to ensure optimal film formation.
- Anticorrosive pigments: Systems with good compatibility, such as zinc phosphate, are preferred to fully realize its anticorrosive potential.
