{"product_id":"3m-vhb-tape-4991-12mm-x-16-5m","title":"3M VHB Tape 4991 - 12mm x 16.5m","description":"\u003cp\u003eThe 3M VHB (Very High Bond) Tape 4991 is a conformable, closed-cell acrylic foam double-sided tape engineered to deliver a permanent, load-bearing bond that replaces mechanical fasteners like rivets, screws, and welds. With a tape thickness of 1.6 mm and an acrylic adhesive system rated for service temperatures from -40°C to +93°C, this 12 mm wide × 16.5 m roll is purpose-built for demanding outdoor and industrial bonding tasks where vibration, moisture, UV exposure, and thermal cycling would compromise lesser adhesives. The grey foam core flexes with substrate movement, distributing stress evenly across the bond line for a joint that strengthens over time rather than fatiguing.\u003c\/p\u003e\u003cp\u003eFor Australian caravanners, 4WD adventurers, and RV owners, 3M VHB 4991 is a go-to solution for caravan bodywork repairs, mounting trim panels, fixing capping strips, sealing roof-rail attachments, and bonding external accessories to aluminium, fibreglass, powder-coated, and painted surfaces — all without drilling new holes that can leak. It handles the relentless vibration of corrugated outback tracks, the harsh UV of the Australian summer sun, and repeated salt air exposure on coastal runs. Whether you're fitting a new awning bracket, reattaching a loose grab handle, or mounting a 12V solar cable trunking inside your motorhome or camper trailer, this tape keeps everything secure and rattle-free on the road and at camp.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eClosed-cell acrylic foam core with grey carrier — 1.6 mm total tape thickness\u003c\/li\u003e\n\u003cli\u003eService temperature range: -40°C to +93°C, suitable for year-round Australian conditions\u003c\/li\u003e\n\u003cli\u003eBonds to aluminium, steel, fibreglass, powder-coat, and many plastics without priming (surface prep recommended)\u003c\/li\u003e\n\u003cli\u003eConformable foam construction distributes load and absorbs vibration along the bond line\u003c\/li\u003e\n\u003cli\u003eUV, moisture, and solvent resistant — maintains bond integrity in exposed outdoor environments\u003c\/li\u003e\n\u003cli\u003e12 mm wide × 16.5 m roll — ideal width for trim bonding, capping strips, and caravan fitments\u003c\/li\u003e\n\u003cli\u003eReplaces mechanical fasteners, eliminating drilled holes that risk water ingress in RV and caravan panels\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eClosed-cell acrylic foam core (1.6 mm thick) — bonds like a permanent structural fastener\u003c\/li\u003e\n\u003cli\u003eRated -40°C to +93°C — handles extreme Australian heat and cold desert nights\u003c\/li\u003e\n\u003cli\u003eUV, moisture, and solvent resistant for long-term outdoor durability\u003c\/li\u003e\n\u003cli\u003eReplaces rivets and screws — no drilled holes, no water ingress risk on caravan panels\u003c\/li\u003e\n\u003cli\u003eConforms to irregular surfaces and absorbs vibration on corrugated outback roads\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"3M","offers":[{"title":"Default Title","offer_id":56393178611878,"sku":"3M-VHB499116MX12MM","price":85.0,"currency_code":"AUD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0466\/4688\/6566\/files\/3M-VHB499116MX12MM.png?v=1776479264","url":"https:\/\/campingaustralia.com.au\/products\/3m-vhb-tape-4991-12mm-x-16-5m","provider":"Camping Australia","version":"1.0","type":"link"}
