POLYPHASE 978 is a broad-spectrum fungistat effective against a wide variety of fungal organisms and is developed to provide efficacy in solvent-based formulations. POLYPHASE 978 offers excellent dry-film fungal protection and enhanced chemical stability. It imparts dry-film protection and prevents discoloration of the protective film due to fungi. POLYPHASE 978 does not change the appearance of materials or have any influence on its coatability. It is compatible with most organic solvent-based systems and provides a broad spectrum of protection against fungi, extending the service life of projects.
