Problems solved by technology

Acrylic resin has the advantages of fast drying, good transparency, good gloss and color retention, and good adhesion, gloss, hardness and weather resistance. Its disadvantages are high minimum film-forming temperature, low film-forming property and flexibility. Poor, poor water and solvent resistance, hot sticky and cold brittle
The molecular structure of polyurethane has a segment structure composed of hard segments and soft segments, which determines its unique properties of being hard and flexible. Its two-phase structure makes water-based polyurethane have excellent low-temperature film-forming properties, leveling properties and flexibility. , good heat back tackiness, but there are deficiencies in stability, self-thickening, solid content, gloss retention, etc.
