TECKREZ Introduces Polymerized Rosins

10.12.09

Teckrez has commercialized two new partially polymerized (dimerized) rosin grades for use in adhesives, wax compounding and other specialty applications. Teckros D85 and Teckros D95 will complement the already established highly dimerized rosin grade, Teckros D140. The new products meet a need in the US market for high acid value, moderate to high softening point rosins caused by closure of the last polymerized rosin factory in the US in 2009.
