Product Description

High Hydroxyl Content Water-based Acrylic Dispersion For Topcoats On Various Metal Substrates

Key Features

High Hydroxyl Content: WEI 3.9% (on solids), making it suitable for high-temperature and low-humidity curing environments.
Excellent Compatibility: Works exceptionally well with both solvent-based and water-based isocyanate curing agents.
Superior Performance: Offers excellent water resistance and a long application pot life.
Cost-Effective Option: Can be used with solvent-based (oily) curing agents for better cost-effectiveness.
pH-Sensitive Viscosity: The product's viscosity and thixotropy increase as the pH value rises.

Physical Properties

Application Guidance

Curing Agent Preparation: Solvent-based curing agents must be diluted to 60-70% with a co-solvent (e.g., BGA, PGDA, or a PMA+DBE 1:2 blend) before use.
Mixing: The main agent and curing agent must be stirred thoroughly after mixing, ideally using a pneumatic or electric stirrer.
Water Dilution: Water addition should be limited to 5-10% of the main agent to avoid a decrease in gloss.
Grinding Restriction: This resin should not be used in the color paste grinding process due to potential stability issues.

Packaging & Storage

Packaging: Available in 20KG, 200KG, or 1000KG wide-mouth plastic drums, or as per customer requirements.
Shelf Life & Storage: 12 months. Store in airtight containers at 5~35°C. Avoid freezing, high temperatures, and physical impact during handling.
