Application

TMG 129 can be used
·for esterifications in oleochemistry
·for catalysis of polyurethane systems
·for curing of silicone resins and silanes
·for polymerisation of lactones to biodegradable polymers
TMG 129 is a liquid catalyst,which distribute well in the reactant.Furthermore,TMG 129 makes an easy proportioning during the running reaction possible.
TMG 129 can be added to the reactants either as it is or blended with alcohols.In esterifications,TMG 129 can be used at a temperature >160℃.
With TMG 129,it is possible to obtain light,clear products.In general,TMG 129 is used in concentrations of between 0.01-0.20%.The removal of TMG 129 from esters is apart from chemical methods,as e.g. by hydrolysis or oxidation,also possible by adsorption with TMG TINEX-products.
