Appendix A
Construction reference
(reference)
A1This product is suitable for spraying and is adjusted with X-3 perchloroethylene release agent. If it is constructed in an environment with a relative humidity of more than 70%, it is necessary to add an appropriate amount of F-2 perchloroethylene moisture-proof agent to prevent the paint film from turning white. A2This product is matched with primer and putty:
Primer: iron red perchloroethylene primer, iron red alkyd primer. Putty: perchloroethylene putty, fat glue putty. If the product exceeds the storage period, it can be retested according to the technical requirements specified in this standard. If the results meet the requirements, it can still be used. A3
