Structural Silicone Sealant for Sun Room Sealing

RTV-1, Acetoxy-curing, Sunroom & glasshouse sealing Fast curing, short SFT Good adhesion & excellent mechanical property

Characteristics

HX-3800 is one-component, acetic-curing silicone sealant with excellent mechanical properties and high curing rate for construction and industrial applications.

HX-3800 cures at room temperature under the action of atmospheric moisture to give a permanently flexible silicone rubber.

Special characteristics

¨        Non-sag

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

¨        Flexible at low (-40°C) and high temperatures (+100°C)

¨        Fast cross-linking: quickly becomes tack-free

¨        Low shrinkage during vulcanization.

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

¨        Good tooling characteristics

Color:

Transparent, Black, White, Grey,

other colors are available according customer's require

Application

Curtain wall structural sealing

Large plate glass sealing

Sealing of joints exposed to high mechanical loads

Sealing of joints which need to quickly build up mechanical strength

Suitable for use in glazing and industrial application and for the construction of silos and containers.

Adhesion

HX-3800 exhibits excellent primerless adhesion to most non-porous siliceous material, e.g. glass, tiles, ceramics, enamel, glazed tiles and clinker;impregnated, varnished or painted wood 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.

Restrictions on use

HX-3800 may be discolored in contact with some organic elastomers, e.g. EPDM, APTK and neoprene.

HX-3800 is not recommended for use on substrates, such as marble, concrete, fibrous cement and mortar, as the product releases acetic acid during curing.

HX-3800 should not be used in contact with metals such as lead, cooper, brass or zinc as corrosion will result.

HX-3800 is not recommended for use on natural stone, such as marble, granite, quartzite, as it can cause staining.

HX-3800 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.
