Professional-grade automotive adhesive and sealant in one. UPOL Tiger Seal Black is a one-component polyurethane formula that permanently bonds and seals body panels, trim, windows, doors, and lights. This 310ml cartridge delivers OEM-quality results trusted by body shops and classic car restorers across the UK. Ready to use with no mixing required—simply load into a standard caulking gun and apply.

Overview

Tiger Seal Black is the go-to automotive adhesive sealant for professionals and serious DIYers who demand reliable, long-lasting bonds without the premium price tag of 3M or Sika alternatives. This moisture-cured polyurethane sealant creates a permanently flexible, non-shrinking seal that withstands extreme temperatures from -40°C to +90°C (up to +120°C for short intervals).

Unlike many competitors, Tiger Seal can be tooled and overcoated immediately after application—no waiting required. This unique feature saves valuable time in busy body shops and ensures your repair work stays on schedule. The black color matches OEM finishes on most vehicle underbody components, door frames, and trim applications.

Applications & Usage Guide

Primary Applications:

Tiger Seal Black is the ideal panel bonding adhesive and automotive seam sealer for a wide range of professional and DIY applications:

• Body Panel Bonding: Quarter panels, roof skins, door skins, and structural repairs

Surface Preparation:

For best results, proper preparation is essential. Clean and degrease all surfaces using UPOL SYSTEM 20 Degreasers (available separately) to remove dirt, oil, grease, and wax. Ensure all loose debris is removed before application. Tiger Seal bonds excellently to bare steel, aluminium, brass, original paint, fibreglass/GRP, most plastics, glass, wood, and ceramic surfaces.

Application Instructions:

1. Cut the cartridge nozzle at desired angle and size
2. Load into a standard caulking gun or pneumatic version at approximately 6 bar (108 PSI)
3. Apply adhesive evenly to one surface in a continuous bead
4. Press materials firmly together within the 20-minute work time
5. Mechanically fix or clamp if necessary until skin forms (30-60 minutes)
6. Tool with water only if smoothing is required
7. Paint immediately if desired—no waiting required

Important Usage Notes:

• Once opened, use within 3 days. Seal cartridge tip and base with aluminium foil to maximize longevity
• Uncured adhesive can be removed with panel wipe; cured adhesive must be removed mechanically
• Contains isocyanates—appropriate PPE required (gloves, eye protection, respiratory protection in confined spaces)
• Persons with asthma, eczema, or isocyanate allergies should not use this product
• Ensure adequate ventilation during application and curing
