Trying to make my own waterproofing sealer
« on: Today at 08:58:31 AM »

Hi follks,

I am a paver sealing and waterproofing contractor down in Florida, and I want to try making my own sealer to cut down on costs and improve longevity for my customers.

I mostly use a two-part water reducible urethane sealer called sealnlock or ureseal h20.

They work great but it gets expensive if you want to provide a result that lasts longer than 2-3 years.

So I looked up the chemical formulations from the MSDS for both. Bear with me here, I may need a chemical engineer but what the heck.

Part A for both is an acrylic polymer CAS Number: Proprietary/Unknown
Product Name: Ure Seal (A component) Description: Polyurethane Dispersion Synonyms: None Molecular Formula: N/A Chemical Family: Section 2 - Hazardous Ingredients Chemical Names(s): CAS Number A) Amine (<4%) Trade Secret B) Glycol Ether (<10%) Trade Secret No OSHA or CGIH limits have been set for these materials Section 3 - Physical Properties Description: Polyurethane Dispersion Specific Gravity: 1.1 Appearance: White, milky PH: N/A Solubility in water: Good Boiling Point: 200°F Evaporation Rate: NIL
Part B is easily purchased through wholesale vendors and shown below.
Polymeric Hexamethylene Diisocyanate <75    28182-81-2 0.5 mg/M3
Hexamethylene Diisocyanate <.25 822-06-0 0.02 PPM

Question: Can anyone point me in the right direction on where to get a high solid 40-50% acrylic polymer from anywhere other than China or India? Will this work with some testing? Thanks
