SS621E Silicone Structural Sealant

1. DESCRIPTION

SS621E Silicone Structural Sealant is a one-component neutral-curing silicone sealant designed specifically for structural bonding applications of bi-facial glass glass PV modules and solar PV curtain wall engineering. SS621E meets global standards for structural glazing, with excellent structural adhesion properties and weather resistance.

2. FEATURES

• Odorless, non-corrosive cure system
• Excellent weatherability and high resistance to ultraviolet radiation, heat and humidity, ozone and temperature extremes
• Remains flexible over a temperature range of -58℉(-50℃) to 302℉(150℃)
• Excellent unprimed adhesion to wide range of substrates including coated, enameled, and reflective glasses; anodized and polyester coated or painted aluminum profiles

3. COMPOSITION

• One-part, neutral-curing, RTV silicone sealant

4. APPLICATIONS

• Bi-facial glass-glass PV modules and solar PV curtain wall engineering
• Silicone structural glazing and protective glazing applications

5. TYPICAL PROPERTIES

Note: Typical property data values should not be used as specifications.

6. PACKAGING

• Cartridge: Net volume 300ml.

• Foil Sausage: Net volume 590ml.

7. APPLICABLE STANDARDS

• ASTMC 1184/American Standard
• ETAG 002/European Standard

8. APPLICATION METHODS

PREPARATION:

Clean all joints and glazing pockets, removing all foreign matter and contaminants such as grease, oil, dust, water, frost, surface dirt, old sealants, or glazing compounds and protective coatings.

PROCESSING AND CURING:

Install back-up material or joint filler, setting blocks, spacer shims, and tapes. Mask areas adjacent to joints to ensure neat sealant lines. Primer is generally not required on non-porous surfaces, but may be necessary for optimal sealing of certain porous surfaces. A test placement is always recommended.

Apply SS621E Silicone Structural Sealant in a continuous operation using a positive pressure.(The sealant can be applied using many types of air-operated guns and most types of bulk dispensing equipment.)Before a skin forms(typically within 20 minutes), tool the sealant with light pressure to spread the sealant against the backing material and joint surfaces. Remove masking tape as soon as the bead is tooled.

9. LIMITATIONS

SS621E Silicone Structural Sealant should not be applied:

◆ To building materials that bleed oils, plasticizers, or solvents– materials such as impregnated wood, oil-based caulks, green or partially vulcanized rubber gaskets or tapes

◆ In totally confined spaces as the sealant requires atmospheric moisture for cure

◆ When surface temperatures exceed 60°C(140°F)

◆ Where painting of the sealant is required, as the paint film may crack and peel

◆ To surfaces in contact with food- this sealant does not comply with Federal Food and Drug Administration food-additive regulations

◆ In below-grade applications

◆ For use as an interior penetration fire stop sealing system

◆ In horizontal floor joints where abrasion and physical abuse are likely to be encountered

◆ To frost-laden or damp surfaces

◆ For continuous immersion in water

10. EXPIRATION DATE AND STORAGE

When stored at or below 27ºC(80ºF)in the original unopened containers, this product has a usable life of 6 months from the date of manufacture.

11. ATTENTION

Check the Material Safety Data Sheet(MSDS) before using the product.

Sealant products are not toxic after fully cured, but should avoid contact with eyes before curing. If contact with eyes, rinse with plenty of water and consult a doctor. uncured products should be kept out of contact with children. The product will release small molecular substances during the curing process, and ventilation should be paid attention to in the construction and curing areas to prevent the concentration of small molecular substances from being too bad for people.
