Sta-Sol® ESS: Alternative Solvent Systems Based on Dimethyl Ester Chemistry

Sta-Sol® solvent systems offer unique performance, safety and compliance benefits for formulators and manufacturers and broad compatibility with other solvents and materials.

Based on dimethyl ester chemistry, these products are designed to both perform effectively and reduce current EHS concerns caused by commonly used solvents that have come under regulatory scrutiny for safety and environmental reasons.

Solvent Replacement Example Applications

We have worked with partners seeking cost-effective replacements for these solvents, such as NMP, acetone, methylene chloride, and isophorone, with specific EHS characteristics, including:

  • LVP-VOC exempt alternatives based on consumer regulations (i.e. EPA Consumer Products Regulations,  OTC, CARB)
  • Products not listed on California’s Proposition 65 as carcinogens or reproductive toxins
  • Non-flammable and non-corrosive alternatives
  • Low evaporation rates and better material recyclability
  • Low odor options based on worker complaints
  • Better toxicological & ecotoxicological profiles, including biodegradability
  • REACH compliance concerns (i.e. not included on Candidate List of Substances of Very High Concern)
  • Products not listed as reportable under SARA hazardous substance or RCRA hazardous waste categories

Featured below are specialty Sta-Sol® formulations based on different ratios of dimethyl esters:

Sta-Sol® ESS I – Efficient and Economical Dimethyl Ester Solvent Blend

Sta-Sol ESS I is widely used in industrial cleaning and coatings systems. This blend features a signature blend of the three dimethly esters: dimethyl adipate, dimethyl glutarate and dimethyl succinate.

ESS I is requested by customers due to enhanced performance and purity when compared to traditional dibasic esters (DBE). It is suitable as a co-solvent in cleaning and coating systems, or as a straight solvent replacement for NMP, Methylene Chloride, and certain glycol ethers.

This product can be an excellent, cost-effective choice for current users of dibasic esters or those looking to replace higher VOC products or other solvents tagged with regulatory restrictions and/or severe safety cautions.

Sta-Sol® ESS 159 – Safer Cleaning & Removal of Polyurethane and Acrylic Resins

Sta-Sol® ESS 159 is used to clean and remove a wide range of uncured polymers, resins and compounds from spray guns, die applicators, tools and equipment. It has been used in polyurethane systems to successfully remove coating residue from tools and equipment in solvent soak tanks, as a line flush, and through the use of ultrasonic cleaning mechanisms.

This product features a preferable environmental, health and safety profile when compared to other solvents typically used in these processes, providing a highly effective alternative to solvents such as N-Methyl-2-pyrrolidone (NMP), MEK, acetone, and methylene chloride.
