I used to enjoy using reassuringly expensive thin Zap but since trying the thin cyano from Poundland I’ve found it just as good and saved a lot of money. 

I agree, I've found no difference in the performance of budget cyanos to the far more expensive named brands. However, cheap PVAs and epoxies are a different matter in my experience, when I believe that you do tend to get what you pay for.

For  general modelling use, inexpensive cyano is usually fine. There are a few truly dire ones around that seem reluctant  to cure but  the main difference between cheap and expensive brands is the purity of the glue. Cheaper ones have more filler in the blend and will go off quicker and tend to have less bond strength. I've used Screwfix cyano for years on models up to 1/3rd scale with 100% reliability.

Cyano was never a problem for me; when I was much younger I worked in sales  for Loctite and they used to fill up our car boots with samples of all their products.😉 

I have to say I’ve noticed that Loctite products tend to be way overpriced when aimed at the mass market. For example, I’ve just checked on the B&Q diy.com website, where 7.5g of their ‘Precision’ superglue in a fancy blister pack is £5.36, against Screwfix’s 50g bottle which is £3.59.

Moisture speed up the curing. Your fingers are slightly moist because we're animals... Unlike that nice dry balsa you actually want stuck...

 

Similarly, breathing on cyano seems to cure it rapidly (thus,  I've never bought activator)

I don’t think the likes of Locktite manufactures much. (An Americain company, founder invented a thread locker, and sold out to a German multinational company 30-40 years ago), are repackagers of stuff they buy in 250 litre drums. There are a couple of grades of superglue, depending on how many times the monomers are distilled (impurity removal), and quality control of the process. There aren’t many real manufacturers. The trick, as always, is how to tell the difference between grade one (dire for us), and the better stuff that suits us better. Price, unfortunately, is not a measure, once the marketing fact shifters have finished nudging reality.

Loctite is essentially one of the  premier suppliers of a range of highly specialised CA-based adhesives and has been for the past 40 years across a number of industries. They probably have more different superglues than anyone else. Whether they actually manufacture the products doesn't really matter to the end user.  Don't let the fact that the hobby market is not their primary market fool you, they are mostly supplying a different clientele than model makers or DIYers. I don't use it myself, due to a developed sensitivity to CA, but various grades were certainly extensively used in my former occupation.
