Their catalog spans everything from adhesives and sealants to electrical components, braking systems, doors, locks, seals, and slide-out parts — making them a true one-stop source for RV dealers and enthusiasts alike. The company operates a group of 13 brands, focused on bringing high-quality, often American-made products to market and filling gaps that other suppliers have overlooked.</p><h3>A Broad Product Range Built Around RV Life</h3><p>One of AP Products' most recognized product segments is <a href="/2843-ap-body-trim-molding-46915">body trim molding</a>. Whether you&apos;re restoring a sun-faded travel trailer or refreshing a Class A motorhome, AP Products offers aluminum insert trim molding in a range of finishes — including Polar White, Colonial White, Black, and Mill Finish — designed to fit securely and deliver a clean, factory-like appearance. These trim solutions are made in the USA and backed by a limited warranty.</p><p>Lighting is another area where AP Products shines.

Product Details

The AP 017-90893 Sikaflex 221 is a professional-grade, one-component polyurethane adhesive sealant designed for demanding marine, RV, and automotive applications. This black-colored sealant provides superior bonding strength and flexibility, making it ideal for applications that require resistance to vibration, thermal expansion, and weathering.

Key Features:

  • One-component polyurethane formula requires no mixing
  • Excellent adhesion to a wide variety of substrates including metals, plastics, wood, and fiberglass
  • Remains permanently elastic after curing for superior joint movement capability
  • Outstanding resistance to weathering, UV radiation, saltwater, and chemicals
  • Paintable once fully cured
  • Temperature resistance from -40°F to 176°F (-40°C to 80°C)
  • Non-corrosive to metals

Sikaflex 221 is commonly used for sealing joints, seams, and gaps in RV bodies, boat hulls, vehicle bodies, and other applications where a flexible, durable, waterproof seal is required. It provides long-lasting protection against moisture intrusion while accommodating the natural expansion and contraction of bonded materials.
