وصف المنتج

Water-based Hydroxylated Acrylic Dispersion for Various Metal and Wood Substrates

This water-based hydroxylated acrylic dispersion is designed for formulating high-performance, two-component polyurethane (2K PU) coatings. It serves as a recommended replacement for Bayhydrol A2470.

Primary Application

Used with water-based isocyanate curing agent to create topcoats and clearcoats for various metal and wood substrates.

Key Features

Fast drying and rapid hardness development
Excellent gloss and fullness
Long pot life (activation period)
Suitable for a variety of construction processes

Physical Properties

Appearance	Milky white liquid
Non-volatile Matter	45 ± 1%
Viscosity	500 - 4,500 mPa*S
pH	7.5 - 8.5
Hydroxyl Value	3.9% (on solids)

Important Note: The product's viscosity and thixotropy increase as the pH value rises.

Application Guidelines

Curing Agent: Must be diluted to 60-70% with a co-solvent (e.g., PGDA or PMA+DBE blend) before use.
Mixing: The main agent and curing agent must be stirred thoroughly, ideally with a mechanical stirrer.
Dilution: Can be diluted with water at 5-25% of the main agent weight.
Grinding: Excellent wettability and can be used in grinding processes with precautions:
- Grinding time should be less than 2 hours
- Grinding temperature should be below 50 °C
- The process contains unstable factors that may decrease stability

Packaging & Storage

Packaging: Available in 20KG/200KG wide-mouth plastic drums or custom packaging
Storage: 12-month shelf life. Store in airtight containers at 5~35 °C. Avoid freezing, high temperatures, and physical damage
