1.What are the characteristics and uses of polyester?
Features:
Highest cost-performance ratio, the most widely used coating.
Good flexibility and adhesion, excellent processability.
Moderate weather resistance, usable for 7-10 years under normal climate conditions.
Main Applications: The mainstay of color-coated steel sheets in construction, widely used for roofing and wall panels in factories and warehouses. Also used in home appliances, furniture, etc.
2.What are the characteristics and uses of silicone-modified polyester?
Features:
Introducing silicone (organosilicon) into polyester resin results in superior weather resistance and durability compared to standard polyester.
Stronger UV resistance and better gloss and color retention (color does not fade easily).
Higher hardness and better abrasion resistance, but slightly less flexibility than polyester.
Main Applications: Suitable for buildings requiring high weather resistance, such as large stadiums, and applications requiring strong scratch resistance.
3.What are the characteristics and applications of high-durability polyester/ultra-weather-resistant polyester?
Features:
This polyester, modified with a special molecular structure, offers performance between standard polyester and PVDF.
It is currently the fastest-growing product in the construction industry due to its excellent balance between cost and performance.
Main Applications: Gradually becoming the mainstream choice for mid-to-high-end buildings, replacing some of the SMP and PVDF market.
4.What are the characteristics and uses of polyvinylidene fluoride (PVDF)?
Features:
Top-tier weather resistance; a recognized high-performance coating.
Excellent UV resistance; exceptional gloss and color retention, typically maintaining its color and luster for 15-20 years without fading or chalking.
Good stain resistance and self-cleaning properties.
Highest cost.
Main Applications: Roofs and curtain walls of high-end public buildings (airports, stadiums, museums), landmark buildings, and highly corrosive industrial environments or coastal buildings.
5.What are the characteristics and uses of plastisol?
Features:
Very thick coating (typically over 200μm), offering excellent durability and corrosion resistance.
Rough texture, available in various embossed patterns, capable of concealing minor defects in the substrate.
Good flexibility, but poor heat resistance; may soften at high temperatures.
Main Applications: Primarily used for wall panels, industrial plant partitions, and components requiring deep drawing (such as tanks and basins).
