Inhibitor NLD-20 is a 20% solution of 2,6-Di-tert-butyl-4-methylphenol in styrene. Inhibitor NLD-20 is used in elevated and high temperatures cure systems for lengthening: 1) The shelf life of a SMC and BMC at ambient temperature; 2) The pot life of a mixture UP resin/peroxide at ambient temperature. An advantage of Inhibitor NLD-20 in comparison with for example p-Benzoquinone is that Inhibitor NLD-20 is very effective at ambient temperature but hardly shows any influence on the cure at elevated and high temperature. Application area can be: SMC, BMC, pultrusion, corrugated sheets and artificial marble.
Inhibitor used at elevated and high temperatures for extending potlife or shelf life; 20% solution in styrene.
