Rhenofit DDA-50 EM Diphenylamine derivative Rhein Chemie Antioxidants >> Amine Rubber - Elastomer (Chloroprene, Butyl …) ADHESIVE >> Water-based Rhenofit ® DDA-50 EM Antioxidant for latex compounds and adhesives 50 % Diphenylamine derivative (Rhenofit DDA) as aqueous emulsion Rhenofit DDA-50 EM prevents damage by oxygen and heat for latex compounds. Being a heat protective agent, it is recommended at higher temperatures. Rhenofit DDA-50 EM is effective against dynamic crack formation caused by oxygen (e.g. in NR). If crack formation is mainly caused by ozone (e.g. in SBR) it has little or no protective effect. Rhenofit DDA-50 EM does not influence the scorch and total curing times. As protection for latex articles: 1.5 - 7.5 phr Rhenofit DDA-50 EM Latex compounds Diphenylamine derivative as aqueous emulsion. Used as an antioxidant for latex compounds and adhesives. Offers prevention against damage by oxygen and heat and efficiency against dynamic crack formation caused by oxygen. Does not influence scorch and total curing times. Use level: 1.5-7.5 phr.
