	SPECIAL RECOMMENDATIONS

Special Recommendations

Room temperature curing. · It is mandatory to use PSI or PSW primer before SG120FD to ensure it’s adhesion to any substrate. Moreover, on some substrates it is necessary to use PS primer before applying PSI or PSW primers. · See manufacturer’s data.
