Hybrid sealant as seam sealer?

[ashy90]

Hi,

The usual PU sealant I buy, Puraflex 40 from Tool Station, has been discontinued. It seems that PU sealants are becoming less and less available and 'Hybrid' sealants are taking its place.

I google searched hybrid sealants which told me: 'A Hybrid sealant combines the best properties of silicone (excellent weathering and UV resistance) and polyurethane (durability, adhesion, and paintability) into a single, high-performance product, often called an MS polymer sealant'.

So, is a hybrid sealant, such as Silkaflex EBT+, suitable to use instead of a regular PU sealant, on chassis / seam sealing? Hopefully yes as I have half a tube of hybrid sealant, and a very tiny amount of seam sealing to do.

Thanks

I used some hybrid sealant on a bodge wing repair, didn't realise it was at the time

Didn't seem to brush as nice and took ages, 48+ hours to cure. Was over painted to hide the mess with stone chip protector paint

It seems that PU sealants are becoming less and less available...

Demand in the specific market (DIY/construction) drives availability. The sealants haven't changed, just the taste of the consumers. The average DIY person wants to buy one tube that does everything for the next twelve months. A professional who uses the stuff every day will carry multiple tubes of gunge and use what is best for the task.

Buy from an automotive bodywork supplier and you will get the correct stuff for the job.

I've used stixall (hybrid) for sealing panels, not as a brushable sealant - but it seems to work fine.
