TPM Solvent (Tripropylene Glycol Methyl Ether)CAS: 25498-49-1
Tripropylene Glycol (Mono) Methyl Ether (TPM solvent) is used in many coating and cleaning applications as a low vapor pressure, low toxicity and water soluble solvent solution.
TPM is widely used as a cleaner and stripper in enclosed settings, as well as in agricultural, electronic, ink, textile and adhesive products.
We supply TPM as a stand-alone solvent, as well as a component in custom-tailored, safer solvent alternatives for several manufacturers and end-users.
Environmental, Health and Safety
Glycol Ether TPM is not subject to reporting requirements under CERCLA, or those established under SARA Title 111 and Section 313.
Because of its low vapor pressure (<0.1 @25ºC (mm Hg)) and higher boiling point, tripropylene glycol methyl ether may be considered exempt as an LVP-VOC from applicable consumer products air quality regulations.
The Consumer Specialty Products Association (CSPA) also identifies TPM (CAS 25498-49-1) as an LVP-VOC.
Combined with its low degree of toxicity, low vapor pressure and exclusion from regulatory requirements, TPM can be an excellent solvent choice for many cleaning and coating applications.
Additionally, Glycol Ether TPM can work well in both polar and non-polar soil removal applications.
Since it is water miscible and compatible with several non-polar ingredients, TPM will also blend with other co-solvents in formulated solutions where varying degrees of solvency and surface performance are desired.
TPM delivers an effective balance of slow evaporation and solvency in many applications, including:
- floor cleaners and floor stripping
- removal of urethane resins in packaging applications
- co-solvent component in hard surface cleaning formulations
- adhesive removal and ink removal
- electronic and agricultural applications
Featured Application: SLA Resin Cleaning in 3D Printing
A widely recognized use of TPM solvent is to clean stereolithography (SLA) resins from printed parts during 3D print post processing.
Our customers use TPM to clean the excess resin from parts prior to UV curing. This is often done using a solvent immersion bath.
As we’ve learned from several of our engineering and prototyping customers, TPM solvent provides a safer, non flammable, low VOC and highly effective option for post cleaning SLA resins during post processing.
Sta-Sol® PS 100 is an optimized blend of safer solvents designed to clean and remove uncured UV resins. PS 100 is designed to reduce tackiness and enhance solvency in resin cleaning, including SLA resin removal.
