Alcoxysilane- where to buy?

Mixe - 17-6-2017 at 13:56

I have a positively HUGE patio outside my house, and was looking for affordable wood protection. There's a brand using silicon that claims to both protect the wood and give it a nice grey/silvery patina when it ages. I bought some and used it on a small portion of the flooring, and it really turned out quite nice. One problem though: INSANELY expensive.

It's a two-component protection, and costs like $100-120 per 6-7 sqm.

Beeing the nosy bastard I am, I promptly pulled the patent from the European patent database and read up. Apparently the first component is just potassium silicate with some added oil. The second component is an alcoxysilane.

Now, the potassium silicate I bought quite easily from german eBay for less than a 10th of the price of the commercial product. The alcoxysilane proves a little harder to find. I can't buy from any of the larger chemical suppliers, since they won't deliver to home adresses and need verifications of your professional status to even consider you as a customer.

Anyone has any tips on where to find some? I need something like 5 - 10 litres.
