Dear Sales Team at Oker-Chemie,

I am interested in your Bentonite products listed on Echemi. For our R&D project Grout-Click (specialized construction wastewater treatment), we are looking for a high-swelling Sodium Bentonite.
Could you please confirm the availability and provide a quote for the following:

1. Product: BentoGrout (or an equivalent high-yield Sodium Bentonite suitable for cementitious slurries).
2. Particle Size: 200-300 Mesh (Powder form).
3. Application: Dry blending for rapid flocculation and structuring of alkaline construction waste.
4. Quantity: We would like to start with a 25 kg sample for laboratory testing. What is the price for this quantity and for a future 1 MT (Metric Ton) order?
5. Technical Data: Could you please provide the TDS (Technical Data Sheet) and confirm the swelling capacity (ml/2g)?
Shipping: We prefer DAP Riga (Latvia). Please let us know if you can include the shipping costs in the invoice.
Looking forward to your professional advice.

Best regards,
Sergejs Gavrilovs
