Engineered for Automotive Excellence
UNICO's sealer and adhesive range has been developed in close collaboration with automotive OEM manufacturers to meet the stringent requirements of vehicle body assembly. Each product is formulated to deliver consistent, reliable performance across the full vehicle manufacturing process — from bare metal to final paint.
Whether used for seam sealing to prevent water and corrosion ingress, structural panel bonding, anti-flutter adhesion, or underbody protection, our products meet international automotive standards and are proven in Pakistan's local assembly plants.

Performance Characteristics
UNICO sealers and adhesives are engineered around six core performance pillars that automotive manufacturers depend on.
High Bond Strength
Lap shear strength exceeding 8 MPa ensures robust, permanent panel-to-panel bonds that withstand operational stresses.
Temperature Resistant
Formulated to maintain full structural and sealing integrity across a wide range of -40°C to +120°C operating temperatures.
Waterproof Seal
Elastic seam sealers create a permanent, watertight barrier that prevents moisture ingress and subsequent corrosion.
Vibration Damping
Anti-flutter and anti-vibration compounds absorb and dissipate panel vibrations, reducing NVH levels in the vehicle cabin.
OEM Approved
All products are approved and validated by automotive OEM partners, ensuring compliance with vehicle assembly specifications.
Corrosion Protection
Salt spray tested to ISO 9227 standards — our sealers and underbody coatings provide 500+ hours of corrosion resistance.
Our Sealers & Adhesives Range
A complete portfolio of automotive-grade sealers, adhesives, and protective coatings designed for the modern vehicle manufacturing environment.
Automotive Body Sealer
Single-component, paintable seam sealer for automotive body seams and joints. Excellent adhesion to primed and e-coated metal surfaces.
Hem Flange Adhesive
High-strength, one-component adhesive for hem flange bonding in door, hood, and trunk lid panels — approved for e-coat oven processing.
Anti-Flutter Adhesive
Flexible, expandable adhesive for bonding large inner and outer panels to eliminate panel flutter and reduce road noise transmission.
Cavity Wax
Penetrating wax-based cavity protection compound that flows into enclosed body sections, providing long-term corrosion protection.
Underbody Coating
Rubber-based underbody protection against stone chip impact, road salt corrosion, and airborne noise — applied by brush, roller, or spray.
Structural Adhesive
High-modulus, two-component structural adhesive for metal-to-metal bonding — replaces welding in critical structural joints.
Technical Specifications
Our sealers and adhesives are tested against internationally recognised test standards to confirm performance in real-world automotive applications.
