DESCRIPTION

DURA-SEAL is a specially formulated polysulfide solvent-free two-component edge sealant hardened by classical reaction of interaction of end SH-group with manganese dioxide.

DURA-SEAL is delivered in the form of a set consisting of component A (base) and component B (curing agent) mixed just before application. After mixing of components, the sealant forms thixotropic and easily applied paste.

After hardening as result of chemical reaction the elastic rubber-like material with high strength properties, resistance to vibrations and atmospheric actions is formed, it has excellent adhesion to surfaces ranging from glass, aluminum to stainless and zinc galvanized steel.

AREA OF APPLICATION

DURA-SEAL is a secondary edge sealant for use in insulation glass systems. DURA-SEAL provides mechanical strength, protects primary sealant and ensures an additional barrier for penetration of water moisture inside insulation glass unit and diffusion of gases.

 ADVANTAGES

-low viscosity;

-easy application;

-optimal curing speed;

-excellent adhesion;

-enhanced UV resistance;

-continuous flexibility

METHOD OF APPLICATION

DURA-SEAL PS component A shall be used only with DURA-SEAL PS component B. For a dosage of components, preparation and application of the

sealant mixture, it is necessary to use the special equipment or tools.

Pot life of the sealant ranges from 30 to 60 min. depending on a batch of the sealant, mixing ratio of components and environmental conditions.

MIXING RATIO (A:B)

100:10 by volume / 100:9 by weight

Mixing tolerance of component B shall be within ±20% of nominal volume of the sealant mixture. Excessive quantity of component B may result

shortening of curing time, adhesive properties of the sealant may deteriorate in this case, on the contrary insufficient quantity of component B will speed

up curing of the sealant mixture but mechanical parameters of the polymerized sealant may deteriorate.

Ambient temperature makes considerable effect on curing speed of the sealant. Rise of temperature will shorten pot-life and increase curing speed

of the sealant. Optimum temperature for processing of the sealant is +23±2 °C.

MIXING AND APPLICATION OF SEALANT

Components of the sealant shall be duly mixed in order to guaranty proper mechanical characteristics of the sealant. Visual control of mixing

properties shall be carried on a regular basis. The mixed sealant should be homogeneous and without “marble stains”.
