HM-SA-AA500 Acid type Silicone sealants

Acidic silicone sealant is a one-component sealing material that cures   upon contact with moisture in the air. It is easy to operate and does not   require mixing before use. Construction can be carried out using a manual or   pneumatic caulking gun. Before applying the sealant, ensure that the   substrate surface is dry and free from contamination such as oil, grease, and   dust. After applying the sealant, the surface should be smoothed before a   skin forms on the surface of the sealant. When designing the joint, it is   important to avoid three-sided adhesion of the sealant.
