naddy Posted December 22, 2009 Share Posted December 22, 2009 Not sure which sikaflex product, but I can recommend Terostat 9220 Link to comment Share on other sites More sharing options...
Mickrick Posted December 22, 2009 Share Posted December 22, 2009 252 221 is an adhesive sealant. 252 is for bonding. So I would suggest that's the one you want. (We use it on boats ) Link to comment Share on other sites More sharing options...
Grubbster Posted December 22, 2009 Share Posted December 22, 2009 Neither - 292 is the stuff Solent Se7ens Web! Link to comment Share on other sites More sharing options...
Stuart McGill Posted December 22, 2009 Share Posted December 22, 2009 Yep... 292 but I struggled to find it recently at a sensible cost so I used Tiger Seal. Will look for my recent thread.... Link to comment Share on other sites More sharing options...
Stuart McGill Posted December 22, 2009 Share Posted December 22, 2009 Link to my recent Sikaflex advert... ended up getting Tiger Seal from ebay. Link to comment Share on other sites More sharing options...
Stationary M25 Traveller Posted December 22, 2009 Share Posted December 22, 2009 I used black 221 bought from a horse-box supply company via e-Bay. Worked a treat. Link to comment Share on other sites More sharing options...
Beverlonian Posted December 22, 2009 Share Posted December 22, 2009 Just to throw in my thoughts. I used 221 to stick the wings and they are still stuck solid (also have work experience of it holdin up in a harsh atmospheric environment. Lately I bought the tigerseal as there was no sika available and it seems good too. My only comment about the tigerseal is that its anti-sag properties aren't so good. Terostat 9220, had the guy from henkel in to advise on bonding two metal elements together and this is what he recommended. Sampled OK but went for the sika alternative There, that covers everything so far 😬 Andy SV in Aztec Orange 'n' Black. Link to comment Share on other sites More sharing options...
Mickrick Posted December 22, 2009 Share Posted December 22, 2009 Well, if we're also talking alternatives (Which wasn't the question of the OP) there's 3M 4200. Which is an adhesive sealant, but sticks so strong, I've seen a wooden toerail have to be destroyed to remove it, after 4200 was used to atatch it. Oh, and Grubbster's correct 292 is bloody strong too. There's a millon alternatives. Edited by - Mickrick on 22 Dec 2009 22:04:21 Link to comment Share on other sites More sharing options...
EFA Posted December 22, 2009 Author Share Posted December 22, 2009 I guess I should also ask, which is best for filling gaps (say up to 8mm ) between GRP panels and a steel spaceframe? I need something which is neat once applied. Is this the return of K2RUM?? Link to comment Share on other sites More sharing options...
Stuart Miller 7 Posted December 22, 2009 Share Posted December 22, 2009 Arnie 292 is "structural bonding adhesive sealant" 291 is "adhesive sealant" 290 is "caulking" You want 291 for sticking the wings on. 292 is fine but not if you ever want to get them off again. It's 290 you want for filling in gaps with a nice finish - it will not aerate like 291 and you'll get a really nice finish. With all 3 products, you can sand with wet or dry paper and paint over if you're really fussy about the finish. Again, with all three, you should ideally use the relevant sikaflex primer, especially if you're sticking to metal. Colour = Black in 290 and 291. White in all 3. If you need a supplier contact then please e-mail me or I can send you some up if you prefer. Stuart Link to comment Share on other sites More sharing options...
Bricol Posted December 23, 2009 Share Posted December 23, 2009 304. Cheaper than 316. sorry - 304 grade stainless steel M5 socket button head screws, with stainless nyloc nuts. Mine haven;t come off in 9yrs . . . 😬 Bri Link to comment Share on other sites More sharing options...
David Brown Posted December 23, 2009 Share Posted December 23, 2009 Guess why 304 is much cheaper - it's corrosion resistance is far less than 316. You get what you pay for. David Link to comment Share on other sites More sharing options...
Mickrick Posted December 23, 2009 Share Posted December 23, 2009 EFA, to get a nice neat finish, use masking tape, then as soon as you've gunned it in, spit on your finger, and wipe out the excess, leaving a nice smooth fillet/finish. Then remove the masking tape before it starts to skin over. Pull the tape towards the fillet, to avoid any stringy bits going onto the area you've masked. Any flat areas, you can smooth with a wet potato. 290 is quite runny. Edited by - Mickrick on 23 Dec 2009 10:27:52 Link to comment Share on other sites More sharing options...
EFA Posted December 23, 2009 Author Share Posted December 23, 2009 Thanks chaps. Luckily Mrs W keeps her spuds in a rack in the garage anyway. I predict the Christmas roast may have a slight polyurathane nose to the spuds! Is this the return of K2RUM?? Link to comment Share on other sites More sharing options...
Bricol Posted December 23, 2009 Share Posted December 23, 2009 Regarding 304/316 - not always- depends on the environment you stick it in . But wing tops on a motor car, 304 is fine. Just don't bolt anything aluminium to the car where they will get damp/salty with 'em . . . Bri Link to comment Share on other sites More sharing options...
Ivaan Posted December 27, 2012 Share Posted December 27, 2012 I've been trying to stick ABS plastic wings on, using Sikaflex EBT, but even after 3 days the wings just peel off. The plastic is very smooth, with an oily surface. I've roughed this up with sandpaper and de-greased with brake cleaner, but the Sika still won't hold. Will Sikaflex 292 do the job? Thanks, Clive.

Roger Ford Posted December 27, 2012 Share Posted December 27, 2012 Are you sure they're ABS and not polythene? Polythene is almost impossible to stick. Where did they come from? If they're the Caterham "race" wings, might be worth asking Grads racer Steve Humphreys at YC Plastics, since he makes them for Caterham. Link to comment Share on other sites More sharing options...
Grubbster Posted December 27, 2012 Share Posted December 27, 2012 292 might be ok if they are ABS Areas of Application Sikaflex®-292 is suitable for structural joints in marine constructions which will be subjected to high dynamic stresses. Suitable metals, particularly aluminum (including anodized finishes), metal primers and paint coatings (2-c systems), or ceramic materials, plastics such as GRP (unsaturated polyester resin), ABS, etc. Clear plastics and mineral glass should not be bonded with Sikaflex®-292. This product is suitable for professional experienced users only. Test with actual substrates and conditions have to be performed to ensure adhesion and material compatibility.

Ivaan Posted December 28, 2012 Share Posted December 28, 2012 Definitely ABS. 😬 Any good sources of 292? Thanks, Clive Link to comment Share on other sites More sharing options...
Stationary M25 Traveller Posted December 28, 2012 Share Posted December 28, 2012 Not cheap is it ? Marine chandlers sell it at around £21 per tube ! Mainly in white, but it won't show under the wings. Link to comment Share on other sites More sharing options...

Area Representative Geoff Brown Posted February 7, 2019 Area Representative Share Posted February 7, 2019 Tiger Seal - cheaper than equivalents but just as effective. Sticks like the preverbial. Used to attach carbon cycle wings six years & 18000 miles ago no problems as yet.https://www.u-pol.com/uk/en-uk/product/tiger-sealtm/adhesives-sealants-plastic-repairs/adhesive-sealants/tiger-seal-polyurethane-sealant-and-adhesive#.XFxb5tL7Spo Link to comment Share on other sites More sharing options...
Area Representative Richard Price Posted February 7, 2019 Area Representative Share Posted February 7, 2019 PU18 is also just as effective.I've broken several cycle wings without the adhesive actually letting go......https://www.ebay.co.uk/itm/PU18-Polyurethane-Sealant-Adhesive-Koi-Fish-Pond-Car-Auto-Boat-Marine-GRP-Joints/121884181273?hash=item1c60dd0319:m:mXpiqPFvuI1vCXFShoyVJWg:rk:11:pf:0 Link to comment Share on other sites More sharing options...
