Crystic 474PA is a thixotropic, pre-accelerated orthopthalic polyester resin with good heat and chemical resistant properties.
Crystic 474PA was developed for use in a wide range of applications throughout the chemical industry, and is suitable for the construction of tanks, pipes and fumestacks to operate in environments where heat and chemical resistance are both required.
It is ideally suited to the fabrication of heat resistant, dimensionally stable moulds for cold and heat assisted contact moulding and hot press moulding processes. Crystic 474PA is a versatile resin suitable for use in contact moulding and automated processes such as pultrusion.
Crystic 474PA should be allowed to attain workshop temperature (18°C – 20°C) before use. It needs only the addition of a catalyst to start the curing reaction. The recommended catalyst is Catalyst M (or Butanox M50). The catalyst should be added at 2% into the resin shortly before use, and thoroughly dispersed.
Crystic 474PA should be stored in the dark in suitable closed containers. It is recommended that the storage temperature should be less than 20°C where practical, but should not exceed 30°C. Ideally, containers should be opened only immediately prior to use.
