What Does High-Solid, Low-Viscosity Mean?
High-solid, low-viscosity, as the name suggests, refers to a material with high solid content and low viscosity. Polyaspartic polyurea resin is a typical example of this kind of material. High solid content means fewer volatile substances in the material, resulting in lower VOC (Volatile Organic Compounds) emissions, making it suitable for creating environmentally friendly materials. Low viscosity enhances the workability of the material, facilitating easier application. Additionally, resins with lower viscosity require fewer diluents, further reducing VOC emissions.
Advantages of Polyaspartic Polyurea Coatings
Coatings derived from polyaspartic polyurea resin boast several environmental benefits:
- High solid content, low or no solvent VOCs.
- No need for high-temperature curing.
- Rapid curing process.
- Fewer application layers required due to thick coating ability.
- Over 90% solid content in application, exempting outdoor unorganized emission collection.
- Minimal wastewater and exhaust emissions. These coatings comply with national environmental protection standards. The high-solid, low-viscosity nature of polyaspartic polyurea resin makes these coatings more environmentally friendly and easier to apply.
Relationship Between Coating Viscosity and Solid Content
The viscosity and solid content of a coating are interrelated, but not in an absolute manner. High-solid coatings are not necessarily highly viscous, and highly viscous coatings don't always have high solid content. Viscosity refers to the relative thickness or fluidity of a coating, while solid content indicates the amount of effective components in the coating. In production, several factors influence the viscosity of a coating:
- Resins with higher molecular weight and concentration may result in higher viscosity.
- Coatings with a higher content of pigments and fillers usually exhibit higher viscosity.
- The use of rheological additives, which also act as thickeners, can increase the relative viscosity. Greater quantities of these additives lead to higher viscosity in the coating.
