The anti-mildew silicone sealant is primarily intended for the kitchen, bathroom, and wet area joints and caulk. In most cases, we noticed that the silicone sealant turns black on the mould's surfaces, especially for the kitchen, sanitary and wet areas. As a result, if a mould-resistant silicone sealant is applied, the likelihood of mould in the sealant is reduced.

All Anti-Mold Silicone Sealants must meet the JC/T885 Grade 0 or Grade 1 standard. They have a standard mildew test process based on the standard.

1. Apply the sealant in a 2mm layer and cure for 7 days under regular conditions.

2. Cut a piece of sealant into a thin slice and test it. (See figure 1)

3. Cultivating mildew on the sealant's surfaces for 28 days.

The difference between Grade 0 and Grade 1 Anti Mildew Silicone Sealant:

Grade 0 Anti Mildew Silicone Sealant means there is no visible mould development under 50 times magnification.

Grade 1 Anti Mould Silicone Sealant requires that mildew cannot be seen with the naked eye, but a few mildew can be spotted using a magnifier.

Some suggestions for choosing an anti-mildew silicone sealant.

1.     Double-check the standard, is it JC/T885? Is it Grade 0 or Grade1?

2.    Choose an anti-mildew silicone sealant based on the weather. We recommend that customers use Grade 0 Anti-mildew silicone sealant in humid climates. In addition, the user's choice of Grade 1 anti-mould silicone sealant is acceptable. Because mildew grows faster in moist areas than it does in dry conditions.

3.     The professional who performs the test is clearer, according to the standard. It also instructs customers on how to select a sealant.
