Neutral-curing, ACP, Alu & Glass sealing Fast curing, short SFT Good adhesion & excellent mechanical property.

Characteristics

HX-1200 is a high-quality, easily applied one-part neutral-curing, low-modulus silicone sealant for construction applications, with a long shelf life and especially good bonding characteristics. It cures on exposure to atmospheric moisture to form a durable, elastic seal.

Special characteristics

¨        Non-sag.

¨        Ready gunnability at low (+5°C) and high (+40°C) temperatures.

¨        Fast cross-linking: quickly becomes tack-free.

¨        Low shrinkage during vulcanization.

¨        Flexible at low(-40°C )and high temperatures(+150°C).

¨        Good tooling characteristics.

¨        Outstanding weathering resistance

¨        Bonds to almost all materials without primer

¨        no migration of plasticizer

¨        Not corrosive to metals

¨        Low shrinkage on curing

Application

HX-1200 is a high-performance sealant designed for sealing, bonding and mending tasks in glazing applications. It is especially suitable or use as weatherseal for structural glazing.

HX-1200 is suitable for use on alkaline substrates such as concrete and mortar.

HX-1200 can be applied by either hand or machine to seal expansion joints and connecting joints in a wide variety of materials,

Adhesion

HX-1200 exhibits excellent primerless adhesion to most non-porous siliceous material, e.g. glass, coated glass, tiles, ceramics, enamel, glazed tiles and clinker; impregnated, varnished or painted wood, aluminum, steel and some plastics.

Users must carry out their own tests due to the great variety of substances.

The adhesion can be improved in many cases by pretreatment of the substrates with a primer.

Weather and heat resistance

HX-1200 has excellent weatherability and is virtually unaffected by UV, radiation, ozone, rain, snow, sunlight and extremes of temperature. Its mechanical and physical properties do not change appreciably on aging or exposure to weather. This has been confirmed in weatherometer tests performed.

Even after many years in service, seals remain fully functional. Cured HX-1200 stays elastic at temperatures from as low as -40C to as high as +150C. It will even withstand brief exposure to lower and higher temperatures.

Restrictions on use

HX-1200 may be discolored in contact with some organic elastomers, e.g. EPDM, APTK and neoprene.

HX-1200 is not recommended for use on natural stone, such as marble, granite, quartzite, as it can cause staining.

HX-1200 is not recommended for sealing of aquaria.

The curing time can be extended at lower temperature, low humidity or by low volume of air change.
