Silicone Sealant Classification and Precautions | JCT Machinery

◪Thoroughly remove all loose particles and dust to ensure that the construction surface is clean, dry and free of grease and surface dirt such as release agents, curing films, hydrophobic agents, etc.

◪Construction should be carried out in a clean environment with a temperature of 4~40℃ and a relative humidity of 40% ~ 80%, and construction should be stopped in rainy and snowy weather.

◪In order to prevent the sealing adhesive from being damaged when the joint expands, the joint shoule be stuffed with a suitable backing material, and the width of the backing material shoule be greater than 25% of the joint width to conrol the thickness of the sealant.

◪A bevel shoule be cut at the outer mouth of the sealing paste tank, and then a squeeze gun shoule be installed to squeeze the sealing paste of the joint. The thickness and width of the sealing paste should be uniform and meet the sealing requirements.

◪The sealant is not completely cured within 48 hours after application, and the sealing joints are not allowed to have large displacements, otherwise the sealing effect will be affected.
