Hard Coated Low-E options in China

Hard coated low-E coating,also named as online low-E,or pyrolytic coated low-E.Different from soft coated low-E coatings,hard coated low-E is produced when manufacturing the float glass.

The biggest advantage of hard coated low-E, is it’s hard and no chemical reaction when exposed in the air.So ,soft coated low-E coatings must be made into insulated glass,while hard coated low-E coatings can be used in single glazing, for example,tempered,heat strengthened, and laminated glass.

The emissivity is about 0.15,which is much higher than soft coated low-E coatings,so glass made with hard coated low-E has higher U value,but this has been the best solution to increase the single glazed units thermal insulation performance.

Hard Coated Low-E options in China

The main manufacturers of hard coated low-E in China are AGC, SYP, Jinjing.Here we introduce the main hard coated low-E coating options in China:

  1. High light transmittance low-E coating.

The low-E coating has light transmittance over 80%,when placing a hard coated coating and clear float glass together,it’s hard to identify them.The typical coatings are AGC-Planibel G, SYP -Energy advantage, Jinjing.

Below is the typical performance data for three different coatings,the only difference, Planibel G from AGC is slightly yellow color,it’s not related to the coating,but the float glass color is yellow color.

  1. Solar shading hard coated low-E coating.

Generally there’re 2 kinds of solar shading hard coated low-E coatings, the first type is coating on clear glass but have lower light transmittance and solar coefficient ,the typical glass are AGC-Sunergy Glass, AGC- Sunergy 48, SYP -SC60.

Another type is coating directly on tinted glass,for example SYP-SFC -coating on French green glass,SYP- SGC -Coating on Eyro grey glass, SGE -Coating on crystal grey glass.Jinjing bronze low-E.
