Specialty Chemicals Manufacturing

Complex formulations with specific industrial applications call for equally exacting manufacturing. 

Seatex, with strategic locations near Houston, Texas, is up to the task of developing your most demanding chemicals, whether they utilize hazardous materials or involve sophisticated processes. We perform custom chemical blending that meets any and all specialty chemical requirements, including:

  • Custom particle sizes to as small as 10 microns
  • Distribution through advanced milling techniques
  • Solid/liquid incorporations
  • Complete molecular change

Whether your specialty product requires liquid blending, dry blending, grinding and milling, or a customized process, Seatex offers a wide range of chemical manufacturing services backed by over 50 years of experience.

How Seatex Meets Your Specialty Chemical Needs

We Handle Even the Toughest Custom Chemical Requirements

Heated Products

For any performance product that requires the addition of heat to achieve your goal, our facilities can accommodate atmospheric reactions up to 400 degrees. In our jacketed tanks and heated shakers, we can use any combination of heating and cooling to reach the right temperature profile for your blended or reacted products.

Flammable Materials

Whether you need to lower a formulation’s freezing point without watering it down, or you need a solvent to allow for pumping a product, a flammable additive such as ethanol is often the best option. With our brand new flammable blending facility, our ability to safely and cost-effectively handle BTEX (benzene, toluene, ethylbenzene, xylene) and other hazardous materials is second to none.

Molecular Change Reactions

As a one-stop-shop chemical manufacturer, we handle true specialty chemistry just as readily as simple mixing. When your formulation’s specs call for complex science, we have the tools and the expertise to produce singular compounds while managing their unique reactions and necessary environments.

Scrubbing and Gas-off

Government bodies and consumers alike demand chemical products that are environmentally friendly, both in their production and their application. In our processes, we effectively scrub VOCs and other unwanted byproducts through negative pressure space inside our tanks. We commonly neutralize ammonia, although we are able to scrub many different types of harmful or unwanted gases that may be generated during molecular changes.
