Tesnilna masa Fischer 53093 rjava 310 ml

Fischer 53093 Brown 310 ml is a neutral silicone sealant formulated for sealing and bonding in building and repair applications. The product is supplied in a 310 ml cartridge and is suitable for use on ceramic, concrete, glass, masonry, metal, PVC, many plastics and wood. It cures to a flexible brown seal with good adhesion and retains properties across a wide temperature range from -40 °C to 150 °C. Typical applications include joints, seams and penetrations where a weather-resistant, flexible seal is required.

Advantages

The sealant offers fast skin formation with an operating time of approximately 15 minutes, enabling quicker handling and reduced downtime. Its neutral curing chemistry minimizes corrosion risk on metal substrates and reduces the chance of staining on sensitive materials. Once cured, the sealant provides long-term flexibility to accommodate thermal movement and vibration. Its resistance to a broad temperature range and weathering makes it suitable for both interior and exterior applications.

Suitable for

• Sealing expansion and connection joints in facades and masonry
• Sealing around window and door frames on metal, PVC and wood
• Sealing sanitary and kitchen fixtures adjacent to ceramic and glass surfaces
• Bonding and sealing trim, panels and seams on metal and plastic components

Key specifications

• Form: silicone paste
• Color: brown
• Volume: 310 ml
• Skin formation / operating time: approx. 15 minutes
• Service temperature range: -40 °C to 150 °C
• Curing: neutral (acetoxy-free) silicone
• Typical properties after cure: elastic, weather-resistant, good adhesion to multiple substrates

How to use

Apply the sealant from the cartridge using a compatible caulking gun. Surfaces must be clean, dry and free from dust, grease or loose particles. Cut the cartridge tip to the desired bead size and apply a continuous bead into the joint or seam. Tool the sealant within the skin formation time to obtain a smooth finish and ensure contact with joint faces. Allow the sealant to fully cure according to ambient temperature and humidity; full mechanical properties are achieved after complete cure.

Recommendations

For best results, store cartridges at moderate temperature and protect from frost before use. Test adhesion on unfamiliar plastics prior to application. Do not apply to surfaces that bleed oils or plasticizers. Use appropriate joint dimensions and backing materials where required to control sealant thickness and movement capacity.
