An Injectable Waterproofing Sealant

In situations where clarity or transparency is required while sealing surfaces and voids, Self-Leveling Clear waterproofing sealant is the perfect solution. This two-component polyurea sealant is completely see-through which allows for thorough inspections without having to remove the sealant. The access it provides makes it a waterproofing and corrosion prevention sealant that can be used in a variety of applications. Av-DEC Self-Leveling Clear is of low viscosity and can be injected according to specific requirements.

On application, the flexible semi-solid sealant provides a watertight seal and a protective covering against abrasion. This is due to Av-DEC two-component polyurea formula. Self-Leveling Clear is compliant with the most stringent Federal Aviation Administration (FAA) regulations for flame retardant sealants, and its non-hazardous nature means it can be applied without excessive paperwork. Other benefits from using the Self-Leveling Clear sealant include:

  • Complete waterproofing against, moisture, and most solids which reduces corrosion and defects in porous assemblies.
  • A flexible semi-solid seal which is easily applied and removed when required which speeds up maintenance activities.
  • An exceptionally quick cure time due to Av-DEC two-component polyurea formula which makes real-time maintenance possible.
  • A clear see-through glossy gel which makes inspecting sealed surfaces and voids possible. This also speeds up maintenance activities.
  • Excellent cohesive properties which makes application on vertical surfaces, painted surfaces, and bare metal possible.

Av-DEC two-component Self-Leveling Clear comes in a standard 50cc as well as a 200cc option. Take advantage of Av-DEC free-evaluation policy to test the Self-Leveling Clear sealant today.

A Clear Polyurea Sealant That Guarantees Transparency

Self-Leveling Clear is a two-component polyurea sealant that integrates all the properties of polyurea. These properties include a quicker time to cure, a durable yet flexible seal, and no emission of volatile organic compounds (VOCs). The two-component formula also guarantees easy application and better cohesive properties than rubber, silicon, and other sealing solutions. The benefits these features bestow on specific avionics and engineering assemblies include:

  • A cure time of 15-20 minutes which is faster than polyurethane and silicon sealants. It also cures under fluctuating temperatures and this drastically reduces downtime due to maintenance.
  • High resistance to abrasion and fluctuating temperatures which makes it an excellent environmental seal for diverse applications.
  • A flexible, durable sealant that does not deform under constant stress, which makes it ideal for external surfaces or assemblies that experience constant traffic.
  • A transparent glossy seal that is both aesthetically pleasing and practical, which yields a working seal that allows for extra scrutiny of sealed surfaces.

A Versatile Seal Designed for Diverse Application

Av-DEC Self-Leveling Clear is a low viscosity sealant that can be injected into voids on surfaces using the right equipment. Its mode of application also means it can be used in diverse situations and on diverse components and assemblies. Self-Leveling Clear can be used to seal off cracks and voids on windows, connector bases, windscreens, ceramic surfaces and more. The benefits of its versatile application include:

  • A watertight seal over assemblies and components surrounded by moisture or water which helps to prevent their degradation.
  • A low viscosity sealant that can seal off cracks and other fissures from water.
  • A durable seal that holds up under excessive vibrations.

An All-Purpose Self-Leveling Sealant for Different Industrial Niches

The two-component polyurea sealant is also self-leveling. It can be applied on any surface regardless of its composition. When applied, Av-DEC Self-leveling Clear will seek to create a level base on the applied surface. This reduces the effects of excessive vibrations. Apply Self-Leveling Clear to prevent corrosion and water degradation in the following industries:

  • Aviation
  • Automotive
  • Naval Engineering
  • Manufacturing
