Silicone sealant CX80 CX-80 40 g tube — silicone adhesive and sealant, neutral cure

CX80 CX-80 40 g tube is a neutral-cure silicone sealant formulated for sealing, bonding and filling small gaps in household and light-construction applications. The product comes in a compact 40 g cartridge suitable for manual application and provides a flexible, durable bead that resists moisture and common temperature variations. Because it cures without acidic byproducts, the silicone adheres well to many substrates including glass, metal, ceramics and most plastics when surface preparations are followed.

Advantages

The neutral-cure formulation minimizes the risk of corrosion on metal surfaces and reduces the chance of staining on sensitive materials. The small 40 g tube is convenient for spot repairs, sanitary joints and window or door sealing where precise application is required. After curing the seal remains flexible to accommodate thermal expansion and movement, and it provides reliable water resistance for interior and exterior use within the product’s recommended limits.

Suitable for

• Sealing sanitary joints in bathrooms and kitchens
• Sealing around windows and doors
• Bonding and gap-filling for household repairs
• Sealing joints on glass and metal surfaces
• Small DIY and maintenance tasks

Key specifications

• Form: neutral-cure silicone sealant
• Packaging size: 40 g tube
• Properties: flexible after curing, moisture resistant
• Application temperature range: suitable for typical indoor and mild outdoor environments (follow manufacturer guidance for exact limits)
• Compatibility: adheres to glass, metal, ceramics and many plastics with appropriate surface preparation

How to use

Ensure surfaces are clean, dry and free of grease, dust or old sealant residues. Cut the tube tip to the desired bead size and apply evenly along the joint, maintaining steady pressure for a continuous bead. Tool or smooth the sealant within the product’s skin-over time to ensure adhesion and a neat finish. Allow the sealant to cure fully according to ambient temperature and humidity conditions before exposing the joint to water or mechanical stress.

Usage recommendations

For best results, test adhesion on an inconspicuous area when using on unfamiliar plastics or coated surfaces. Use appropriate personal protective equipment and ensure adequate ventilation during application. Store the unopened tube in a cool, dry place and use within the recommended shelf life. Avoid contact with acidic surfaces and remove uncured silicone with a suitable solvent according to safety data.
