Water-based Hydroxyl Acrylic Dispersion For Two-component Polyurethane Coatings

Core Product Profile

A water-based hydroxyl acrylic dispersion designed for formulating high-performance two-component polyurethane coatings when combined with a water-based isocyanate curing agent.
Primarily used for topcoats and clear finishes on various metal substrates. Also suitable as a resin for integrated primer-topcoat systems.

Key Performance Features

Superior protection: Excellent water resistance, salt spray resistance, acid and alkali resistance, along with a relatively long initial water resistance time, making it ideal for outdoor applications and harsh environments.
Excellent adhesion: Performs well on a variety of substrates.
High cost-effectiveness: Offers high performance at a competitive cost.
Strong compatibility: Can be paired with both water-based and solvent-based curing agents, providing formulation flexibility.

Physical Properties

Application Guidelines

Recommended co-solvents:
- For main agent: DPNB, PNB, DBG, BG
- For dilution: PGDA, PMA, PMA+DBE (1:1 or 1:2 mixture)
Important notes:
- High initial viscosity after mixing A/B components may shorten the pot life.
- Not recommended for paste grinding due to potential stability issues that may impact performance.
Viscosity adjustment: If viscosity decreases during storage (due to pH drop), it can be readjusted by adding a 10%-20% diluted DMEA aqueous solution.

Testing Example

Recommended curing agent: WL-AC300 (for primer-topcoat systems)
Mixing ratio: 4 : 1 (base resin : curing agent)
Film thickness control: Up to 85μm without pinholes.
Curing process: Baking at 80℃ for 2-4 hours followed by ambient curing for 1-7 days results in excellent salt spray resistance.

Packaging & Storage

Packaging: 20KG/200KG/1000KG wide-mouth plastic drums, or customized per customer requirements.
Shelf life: 6 months.
Storage conditions: Store in sealed containers, protected from freezing and high temperatures. Recommended storage temperature: 5~35℃.
Usage recommendation: Use shortly after opening.
