CH-50 Relevant Identified uses of the substantce or mixture: Curing Agent Product Description: Dibenzoy1 peroxide,powder,50% with dicyclohexy1 phthalat CAS No.: 94-36-0 EINECS/ELINCS No. : 202-327-6 TSCA status: listed on inventory Specifications: Appearence, 10-20℃: White free flowing power Assay: 49.0-51.0% Water: 2.5% max Bulk density: 0.640g/cm3(40lb/ft3) Other Description: XIAMETER(R) MHX-1107 FLUID Methylhydrogen Siloxane Trimethylsiloxy-terminated Applications: Silibase-CH50 is a free flowing,fine,granular power containing 50% dibenzoy1 peroxide for the curing of unsaturated polyester resins and acrylic resins at ambient and elevated temperatures.At temperatures up to 80℃, Silibase-CH50 Should be used in combination with an aromatic tertiary amine accelerator, above 80℃ the use of an accelerator is not required. Silibase-CH50 is easy to handle, easy to disperse and dissolves very quickly in unsaturated polyester resins and acrylic resins.When in acrylic resins a very high degree of transparency of the cured part is required the special grade Silibase-CH50 is advised. The curing system Silibase-CH50 amine accelerator shows a very fast cure that is hardly influenced by humidity and fillers.Even at low temperatures a relatively good cure will be obtained. A disadvantage may be the yellow color and poor light resistance of the moulded product. For ambient temperature curing the following amine accelerators are available to adjust the gel time and speed of cure of the cure system based on Silibase-CH50: Accelerator NL -65-100(N,N-Dimethy1-p-toluidine) for short gel times Accelerator NL-63-100(N,N-Dimethy1aniline)for medium gel times Accelerator NL-64-100(N,N-Diethy1aniline)for long get times
