Antas-191 is a one component, neutral curing silicone sealant with low modulus and clear color. It cures by absorption of atmospheric moisture to form a flexible and durable elastomeric sealant. It can be specifically used for glass curtain wall, glass rooftop. It can also be used for metal and stone sealing.
