Silicone High-Load Sealant Amtra BIS 20-A13, Gray, 85 g

Amtra BIS 20-A13 is a gray, high-load silicone sealant in an 85 g cartridge designed for sealing joints and gaps that require durable, flexible adhesion. The formulation provides resistance to mechanical stress while maintaining watertight performance, making it suitable for installation, repair and maintenance tasks on materials compatible with silicone-based sealants.

Advantages

This high-load silicone sealant cures to form a flexible, resilient joint that withstands movement and repeated mechanical stress without cracking. Its gray color blends with many construction and equipment surfaces. The product offers reliable adhesion to a range of non-porous substrates commonly used in installations and repairs, and the small 85 g size is convenient for targeted applications and maintenance tasks.

Suitable for

• Sealing joints and gaps in installations and building elements
• Maintenance and repair of equipment with silicone-compatible surfaces
• Areas requiring watertight seals subject to movement or mechanical load
• Small-scale professional and DIY sealing tasks

Key specifications

• Color: gray
• Formulation: high-load silicone
• Package size: 85 g tube
• Cured property: flexible and resilient joint capable of withstanding mechanical stress
• Application: sealing joints and gaps on silicone-compatible substrates

How to use

Prepare the surfaces by ensuring they are clean, dry and free of dust, grease or loose particles. Cut the tube tip to the required bead size and apply the sealant evenly into the joint or gap, ensuring full contact with the adjoining surfaces. Smooth the bead as needed with a suitable tool or spatula before skin formation. Allow the sealant to cure according to ambient temperature and humidity; avoid disturbing the joint during curing to ensure optimal mechanical performance.

Usage recommendations

Use on surfaces known to be compatible with silicone sealants; test adhesion on unfamiliar materials before full application. For best results, maintain recommended joint width-to-depth ratios and follow standard surface preparation practices. Store the product in a cool, dry place and use within the manufacturer’s suggested shelf life to preserve application properties.
