L&L Seal

Sealing Without Compromises

L&L Products develops sealing materials to enhance a component’s durability by preventing water ingress, pollutants and odors from intruding.

L&L Seal

Offering robust sealing solutions for 50+ years

In the 1970s, we developed heat-activated polymeric sealing materials. Since then, we have worked consistently on optimizing our sealing technology by leveraged our polymer science and adhesion technology expertise and expanded our portfolio offerings.

Let’s Get in Touch!

Are you interested in our Seal Solutions? We look forward to a conversation!

Seal Solutions

Our custom-formulated sealing materials are designed to completely fill and seal a cavity to prevent the intrusion of water, air, dust and fumes into the interior. By sealing even the most complex cavities, our solutions help to reduce metal body corrosion associated with water leaks and reduce noise, vibration, and harshness (NVH).

Ambient Curing Sealants

Ambient curing sealants

In addition to our Heat-Activated Sealants, we broadened our offerings by providing a series of innovative one-component sealants that completely cure at room temperature. Our Ambient Curing Sealants can be offered with an accelerator paste. The materials have a wide range of mechanical properties, from elastic sealants to creep-resistant elastic low-strength adhesives.

L&L Ambient Curing Sealants are free of solvents, VOCs, and toxic isocyanates. Our sealants allow for direct adhesion to many substrates without primers or pretreatments.

L&L XiP® (eXtrude-in-Place™) Technology

eXtrude-In-Place® (XiP®) technology

Our eXtrude-In-Place® (XiP®) technology combines custom formulated chemistry with the capability of a fully automated application process. It involves extruding and applying an L&L formulation directly onto a substrate by robotic application.

XiP® compatible materials offer good wash-off resistance. Beyond that, they are formulated to be dry-to-the-touch immediately after being extruded onto the substrate, which leads to improved handling and enables the customer to stack or nest several parts, resulting in minimized packaging costs.

eXtrude-In-Place® (XiP®) technology

  • Dry-to-touch
  • Versatile design capability
  • Superior green state adhesion
  • Good wash-off resistance

eXtrude-In-Place® (XiP®) benefits

  • High level of repeatability for applications of varying complexity
  • Improved acoustic and sealing performance
  • Improved handling
  • Minimized packaging costs
