Overview Details Application Documents

Product Description

AC 650 Mould Resistant is a one-component, solvent-free, neutral-cure silicone sealant which does not emit unpleasant odors, available in the form of a thixotropic paste. It is easy to apply on vertical and horizontal surfaces and cures at room temperature through the humidity present in the air to form a flexible sealant. Seals are extremely stable over time, even when exposed to different weather condition, industrial environments, and temperature changes. The product remains flexible between -40°C and +150°C.

Field of Application

AC 650 Mould Resistant is used to make watertight seals in joints and gaps between similar and different types of building materials, including those permanently exposed to damp conditions. Once polymerization has taken place, it forms a perfect, flexible seal which adheres well to glass, ceramic and painted metal surfaces and is highly resistant to the formation of surface mould.

It is used for:

· Mould resistant seals in bathrooms, kitchens, laundry rooms and damp environments.

· Sealing sanitary fittings, bath-tubs, shower booths and saunas.

· Sealing greenhouses.

· Sealing U profile glass (U-glass).

· Sealing between glass and window frames.

· Sealing air and water vents.

Application Procedure

Preparation of substrate

Surfaces to be sealed must be dry, de-greased, solid and free of dust, loose parts, oil, grease, wax, old paintwork and rust on metal surfaces. We recommend applying masking tape along the edges of the joint in order to avoid the sealant seeping out of the joint and to get a more attractive finish.

Preparing the product

Ready to be used.

Applying the product

Insert the cartridge in an extrusion gun, cut off the tip of the cartridge, screw on the extrusion nozzle, trim the nozzle at an angle of 45° and according to the extruded width required and squeeze out the product in a continuous flow into the joint while trying to avoid air entering the joint. Immediately after applying the sealant, smooth over the surface before it hardens with a spatula wetted with soap and water. Remove the masking tape immediately after smoothing over the sealant
