Flamemaster Chemseal CS 415 B-1/2 is a two-part, aluminium-coloured polysulphide sealing compound supplied in a pint kit. It is designed for sealing external aircraft seams, depressions and gaps where weather tightness and aerodynamic smoothness are required.

The Class B material is thixotropic, providing low-sag handling for application by extrusion gun or spatula. Flamemaster states that the cured sealant offers adhesion to a range of coated and bare aircraft substrates, flexibility, and resistance to jet fuel, water and other aerospace fluids.
