Delamination Acrylic Adhesive S1227 is a two-component, transparent acrylic adhesive (cement) for the high-strength bonding of plastics such as acrylic and perspex.

This adhesive is particularly suited to repairing delaminated acrylic windows in caravans. It is the replacement for our S1220 which was our most popular product for delaminated caravan window repair. The S1227 offers some very important advantages over the original S1220.

  1. The most common issue raised by users of the S1220 was that the open time was very short, only 1-2 minutes. The S1227 offers the user a much better open time of approximately 15-20 minutes.
  2. The S1220 was only available in 25ml due to the restriction on the size of the self plunger type cartridge which meant that the maximum bead length was only 1.5m. As the S1227 comes in a bottle we can increase the amount of adhesive provided meaning that for almost the same price as the original S1220 the user now gets enough adhesive for 3-5m bead length. This makes the product even more economical relative to the price of a new window.

The S1227 is easy to use, dries clear and once cured forms a bond that is stronger than the window itself.

Typically used for

Delamination Acrylic Adhesive S1227 is a very versatile product which will bond a wide variety of industrial plastics without the need of primers or surface treatment.

Some typical examples of what this adhesive is good at bonding and for use on:

  • Delaminated acrylic windows in caravans, motorhomes and boats
  • Caravan window repair
  • Caravan window repair glue
  • Caravan window repair adhesive
  • Delaminated window glue
  • Delaminated window adhesive
  • Polyplastic window repair

Product Specifications

This adhesive is supplied in two separate bottles, Part A being the adhesive and Part B is the activator. Once mixed together the adhesive will start to cure and therefore should be used within 20 minutes of mixing. This kit is designed to be used for a single application. Please do not try to decant smaller amounts of each part as the ratio is specific and you have been provided with exactly the amounts required. If you have more than one window to repair please purchase multiple kits rather than trying to split down a single kit.

High strength bond with high environmental resistance

Once bonded, this fusion of chemistries achieves an ultra high strength UV stable bond with excellent chemical and environmental resistance.

Directions for use

  1. For optimum performance surfaces should be clean and free of grease.
  2. Remove the top from both Part A and Part B bottles and pour all of Part B into the larger Part A bottle.
  3. Replace the top on the Part A bottle and shake vigorously for 2 minutes.
  4. Take the cap off the Part A bottle and cut the nib off the top of the bottle down to the ridge.
  5. Gently apply the adhesive along the centre of the delamination with a bead not exceeding 5mm wide as this will spread across approximately 15mm.
  6. Check the coating has no gaps that may allow moisture through and thus prevent sealing properly.
  7. Bring the top pane down to the bottom pane and apply immediate pressure to make sure both panels touch everywhere thereby avoiding gaps.
  8. If gaps are visible the panels can be lightly clamped to ensure all gaps are mated. Clamping should be achieved using clothes pegs or light spring clamps but not heavy duty clamps as this may cause a spiderwebbing effect.
  9. It is always easier to remove any excess adhesive prior to cure.
  10. Once you have used the adhesive leave the cap off the bottle and set outside in a safe location for at least 3 hours. DO NOT touch the bottle in this time as it will get very hot.
  11. Allow the adhesive sufficient time to achieve handling strength before moving or unclamping components.
  12. Once product has fully cured, polish any adhesive outside of the bondline with a soft cloth to achieve a deep shine.
  13. Please allow at least 6 hours before refitting the window. When refitting ensure that a large and fast change in temperature does not occur. ie. if the repair has been undertaken in the cool of a garage, please don’t refit the window in the middle of the midday heat. Wait until the evening to allow the window to change temperature more gradually.

Packing and storage information

S1227 should be stored unopened in a cool dry location, out of direct sunlight, at approximately 5-25°C. This grade can offer a 6 month shelf life from manufacture.

Please note

  • One 45ml set will bond approximately 3m-5m in length.
  • Each set is single use, once mixed the adhesive cannot be used again outside of its working time.
  • If you only have a partial delamination we would recommend using WC105 instead to reduce waste. WC105 can be re-used if stored correctly thereby offering better value for money as well.

  1. Brian Newlyn

    Used the product as instructed on a cool day with plenty of small plastic clamps, applied the glue and sealed the two panes together and lightly clamped for 6 hours, superb job and fixed the issues in two windows. I have taken the caravan away for 4 nights and no problems with towing or water ingress and repair is strong and solid.

  20. Eric Butterworth

    Excellent product with plenty of time to position before it sets

  21. Mark

    After following the instructions to the letter, the acrylic spider crazed! Not happy. A waste of money.

  22. Don Sykes

    Was advised to use this on my delaminated caravan window by the service technician, instructions worked perfectly and the adhesive was easy to use and did a great repair on the window

  23. Mark Haynes

    Very fast delivery. Straight forward to use following instructions. Great result, can’t fault it.

  24. Chris

    Used on delaminated Hymer caravan window fantastic results stronger than original bond

  25. Jayne Anthony

    We followed the instructions for how much to snip from the tip of the applicator bottle but this actually made the line too thick and has left adhesive visibly inside the caravan window. On the second bottle used we did not cut the end and this worked perfectly. The caravan has been out on a trip and the product otherwise performs well.

  26. C C

    Used the adhesive to delaminate caravan window that had come apart. The instructions that came with the adhesive made a quite daunting and important repair simple. Great product and worth the money. Cheap imitations don’t work.

  27. Derek s yates

    Spot on

  28. Brian Bristow

    Worked as described. There is no sign of failure of the adhesive. Good after-sales service (I asked what to clean the mating surfaces with (the immediate answer was meth. spirits).

  29. Shaun lawton

    Fantastic, done job perfectly

  30. Martin Gillard

    Called up to ask for best adhesive for window delamination, they recommend S1227, delivery within 48 hours. Followed clear instructions and my caravan window is like new. Highly recommend bondrite

  31. Richard

    The glue set faster than I’d like

  32. Chris Silk

    The product is excellent and the delivery was prompt but as I was repairing the small caravan door window I wasted 70% . You really should stock smaller quantities.

  33. Jon T

    Excellent instructions, and product. Preparation is everything- and have plenty of light spring-clamps to get an even bond. As it says in the instructions- don’t put excessive pressure on the join, as the heat from the reaction can crack the perspex around the pressure-point. Will use again if another window delaminates.

  34. David wayman

    Fantastic product, easy to use and very effective

  35. SAL

    Does what it says it will do. Brilliant repair, straight forward instructions.

  36. Graham Ford

    Does what it says on the bottle. However once Windows were put together the glue ran all over the inside of window and spiders Web appearance. So will need to replace the window. It’s difficult to know how much to use to prevent this. Window still leaked in one place

  37. John Langford

    Used this product on my caravan bathroom window followed instructions and it worked spot on fully recommend this product. saved over £500.00 + on a new window.

  38. Howard Collins

    used this after reading another review had broken the inside of a caravan window this product is as strong as the original plastic so effected a good repair a lot cheaper than a new widow at over £600 Easy to use and very effective.

  39. John kerr

    Fixed the caravan window where it had delaminated all the way round brilliant adhesive thank you

  40. Ann Baker

    The caravan front centre window delaminated after a recent storm and strong winds (not bad for 20 years old though). This was the first time using this product and we will most certainly use it again should we have similar problems. The key advice would be ‘preparation’ before starting. The recommended curing time is 6hrs but we left the window for 48hrs before refitting and as they say ‘you can’t see the join’. Early days but would hghly recommend this product which is much cheaper than a new or replacement window.

  41. Trevor P

    Excellent product, does exactly what it should, but take care not to use too much as you will get runs, but that was down to me, not the product.

  42. Patricia McDermott

    We were very pleased with the result. For relaminating caravan window. Our hope is that it will last, only time will tell.

  43. Dean Butler

    Used previously the old type went off very quickly, this one has a slower cure time a lot better to use and give you more time to get the right bead around the window.

  44. K Bedford

    First class service followed by a first class product. Many thanks.
