Product Description

It is liquid at room temperature, so it is easy to use and process. The glass transition temperature is -80℃ (-112℉) with excellent low temperature properties. The mechanical properties of its elastomer products are close to PTMG.

It possesses excellent low-temperature mechanical properties and a wide temperature range of use.

Due to its good molecular flexibility, it can replace PTMG in flexible artificial leather and ink. It can also be used for low-temperature resistant adhesives, coatings, polyurethane elastomers, etc.

Packing & Storage

Packed in 50kg/drum, 170kg/drum, The storage period is 1 year.

Safety instructions:

Storage should be at cool, dry and ventilate. The best condition is among -20 ~ 38℃. Shelf life of 12 months, if expire, still used if up to standard through retest. When transportation should avoid rain, sunlight. Don’t mix with strong oxidizer.
