Two-Component Fast Curing Structural Silicone Sealant For Curtain Wall Sealing

RTV-2,Fast curing rate; Curtain Wall Adhesion and sealing; Double Glazing Sealing; High strength; Long shelf life;

Characteristics

HX-8810 is two-component, neutral-curing, high strength silicone sealant with long shelf life, designed and tested for the construction and structurally glazed curtain wall.

HX-8810 cures at room temperature under the action of crosslinker and catalyst in part II 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)

¨        Excellent weatherability and high resistance to UV.

¨        Low shrinkage during vulcanization.

¨        Good compatibility with substrance

¨        Non-corrosive to metals, odorless

¨        Meet global standards for structural glazing

Color & Package:

Part I: 190L   White

Part II: 20L    Black

Application

Silicone structural glazing in curtain wall; such as factory glazing of unitized curtain wall systems or install curtain wall on site.

Standards

HX-8810 two-component structural silicone sealant meets or exceeds the requirements of the following specification:

ASTM specifications:

C1184, type S

C920, tyoe S

European Standard:

ETAG 002

China Standard:

GB 16776

Adhesion

HX-8810 exhibits excellent primerless adhesion to many substrates, e.g. glass, tiles, ceramics, enamel, glazed tiles and clinker;  metal, e.g. aluminium, steel, zinc or copper; impregnated, varnished or painted wood; and many 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-8810 may be discolored in contact with some organic elastomers, e.g. EPDM, APTK and neoprene.

HX-8810 is not recommended for use on natural stone, such as marble, granite, quartzite, as it can cause staining.

HX-8810 is not recommended for sealing of joints continuous immersed in water.

HX-8810 can not in contact with food.

The curing time can be adjusted by change the rate of Part II and not influenced by humidity.
