SE6670M Solvent-Based Hydroxyl Acrylic Polyol Resin 2k Automobile
Refinishing Paint
Product Introduction
SE6670M is a solvent-based acrylic polyol resin with 3.0% hydroxyl
content (based on the theoretical calculation of non-volatile
components). It is used to prepare solvent-based two-component
polyurethane coatings mixed with aliphatic isocyanate curing agent.
It is suitable for cement permeable paint, anticorrosive paint, PU
finish paint and floor paint.

Performance
High gloss, good leveling property;
Excellent chemical resistance;
Fast drying speed, high hardness.
Application
It is mainly used in combination with Desmodur N75, N3390, N3600
and other curing agents, and can be used to prepare self-drying or
low-temperature baking cement permeable paint, anticorrosive paint,
PU finish paint and floor paint.
Storage
The resin should be stored indoors in original, unopened, undamaged
container in a dry place at storagetemperature no more than 30ºC.
Exposure to direct sunlight should be avoided.Under above mentioned
storage condition, the shelf life ofthe resin will be 730 days
after production.
