Application

-The initiator of unsaturated polyester resin
ALKENOX P-100 has low decomposing temp(44
).  It is suitable for pulltrusion mold, continuous laminating and large scale mold. Especially large scale moding, heating furnace is needed to get a high temperature. ALKENOX P-100 which has low decomposing temp is suitable for that cases. ALKENOX P-100 is also used with other curing agent such as BPO(Benzoxl peroxide), TBPB(t-butyl-perbenzoate) and other metal salt accelerators. In that case, we can expect a improved properties after curing.

- Polymerization initiator of VCM(Vinyl Chloride Monomer)  
ALKENOX P-100 is used for polymerization of VCM which is the monomer of PVC at 40~70


- Polymerization initiator of other monomer
ALKENOX P-100 is used as initiator of homopolymer
- ization & copolymerization of acrylate,  methacrylate

ane vinylidene floride monomer-

- Storage
   ALKENOX P-100 is quite active peroxide. However handling it at room temperature is possible as it's storage stability at room temperature is a rather high so it is possible to handle at room temperature.    But it can be decompesed at above 25
, so it must be stored under 20 and kept away from direct sunligiht

- First aid
   Skin contact cause a hazard like other peroxides, so appropriate protection is needed. During working, protective clothes and protective hand cream is needed.
---Eye Contact : Immediately flush eyes with plenty of water.                                          
Get medical attention immddiatly

---Skin Contact : Immediately flush skin with   plenty of soap and water. Get medical  attention immediately.

---Ingestion : Not to vomit. Get medical attention
