Coventry™ 12857 Nonflammable Swelling Solvent and Cleaner

Coventry™ 12857 Nonflammable Swelling Solvent and Cleaner is a low-VOC, nonflammable solution developed for safely swelling silicone near sensitive plastics. It is also effective at quickly removing oils, dirt, dust, and other contaminants from hybrid surfaces and assemblies. This high-purity solvent was developed for swelling silicone elastomers and tubing for fitment onto components while in proximity to titanium, PEEK and stainless materials without harming any of the materials. The solvent then evaporates allowing the elastomer to shrink back to its original dimensions. Utilizing novel VOC replacement chemistry that does not contain any hazardous air pollutants or ozone-depleting compounds, this material provides the swelling and cleaning strength required for the most difficult jobs.

Coventry™ 12857 Nonflammable Swelling Solvent and Cleaner is used to clean and prepare a variety of surfaces within critical environments:
• Swelling elastomers
• Carrier fluid for depositing silicone lubricants
• Cleaning
• Extraction
• Drying agent

How do I figure out the shelf life of a product?

The shelf life of a product can be found on either the technical data sheet (TDS), available on the product page, or by looking on the certificate on conformance (COC). The COC can be downloaded by going to https://www.chemtronics.com/coc. Once you have the shelf life, you will need to add it to the manufacture date for a use-by date. The manufacture date can be identified by the batch number. The batch code used on most of our products are manufacture dates in the Julian Date format. The format is YYDDD, where YY = year, DDD = day. For example, 19200 translates to the 200th day of 2019, or July 19, 2019. This webpage explains and provides charts to help interpret our batch numbers: https://www.chemtronics.com/batch-codes.
