Unsaturated Polyester (UP)

Thermoset materials are usually liquid prior to curing and designed to be  molded into their final form, or used as adhesives. Others are solids like that of the molding compound used in semiconductors and integrated circuits (IC).
Once hardened a thermoset resin cannot be reheated and melted back to a liquid form. 
Thermoset materials like unsaturated polyester, vinyl ester, Epoxy, Acrylates (acrylic sheets) and polyurethane.
Focusing on Unsaturated polyester and Epoxy systems

A)  Ambient curing resin systems 
Unsaturated polyester resin systems cured under ambient (cold cure) temperature. Used in various applications like:  

Reinforced UP products (GRP) AkzoNobel Functional Chemicals (XTP) BYK
Non-reinforced UP products  AkzoNobel Fucntional Chemicals (XTP) BYK
Gel Coat AkzoNobel Fucntional Chemicals (XTP) BYK
Putty AkzoNobel Fucntional Chemicals (XTP) BYK
Wood Sealer AkzoNobel Fucntional Chemicals (XTP) BYK
Acrylic sheets (Acrylates) AkzoNobel Fucntional Chemicals (XTP) BYK
Marble Glue AkzoNobel Fucntional Chemicals (XTP) BYK


B) Closed Mold (Hot Cure)

Systems are cured at high temperature.

•    AkzoNobel offers organic peroxides that are used for the curing of unsaturated polyester resin at elevated temperature. Preferred for the curing of unsaturated polyester resin based Hot press molding formulations (SMC, BMC, ZMC, etc).
•    BYK offers additives for RTM, SMC, BMC and pultrusion, wet mat molding and printed circuit boards are available. 

SMC AkzoNobel Fucntional Chemicals (XTP) BYK
BMC/DMC   BYK
Pultrusion AkzoNobel Fucntional Chemicals (XTP) BYK


Products range to:
•    Improve wetting and air release
•    Prevent separation and sedimentation
•    Increase homogeneity 
•    New for these applications are the processing additives.

C) Resin Production
•    AkzoNobel Offers initiators/peroxides for resin production
•    Trigonox B
•    Trigonox C

•    BYK offers additives for polymer production
