TWEHA 20two

High-performance polysiloxane sealant for glazing and façade applications

TWEHA 20-two is a high-quality, exceptionally weather-resistant and durable polysiloxane-based sealant, specially developed for professional glazing, curtain wall and façade applications.

Thanks to its permanent elastic properties and extremely high movement capability, TWEHA 20two provides a reliable and durable seal for joints exposed to movement, changing temperatures and demanding weather conditions. The sealant is easy to apply, even at low temperatures, and shows minimal stringing during application.

TWEHA 20-two is the professional choice where maximum elasticity, weather resistance and long-lasting sealing performance are essential.

Utviklet for ytelse og effektivitet

Ingen mekanisk festing nødvendig

Dette gjør skruer og nagler overflødige, slik at panelene kan beholde et rent og sømløst arkitektonisk utseende.

Frihet i designet

Panelene kan utformes tynnere og lettere, uten at det er nødvendig å ta hensyn til mekaniske forankringssystemer.

Høy ytelse

Gir utmerket vedheft, strekkfasthet og skjærfasthet, noe som sikrer langsiktig strukturell pålitelighet.

Påføring uten grunning

Det er ikke behov for aggressive limgrunnere på de fleste underlag, noe som reduserer installasjonstiden og kostnadene.

TWEHA 20-two combines excellent application characteristics with outstanding long-term performance:

01

Neutral-Curing and Low-Odor

Contains no organic plasticizers or solvents for a cleaner application.

02

Exceptional Elasticity and Movement

Remains permanently soft and elastic, with a low modulus and movement capability of approximately 50%.

03

Excellent Application Properties

Offers excellent rheological, application and adhesion properties, with minimal stringing and easy processing—even at low temperatures.

04

Compatible with Glass and Metals

Non-corrosive on metals and compatible with PVB interlayers and insulating-glass edge seals.

05

Outstanding Weather Resistance

Resists sunlight, rain, snow, ozone and extreme temperatures while providing excellent long-term durability and ageing stability.

TWEHA 20-two is particularly suitable for:

TWEHA 20-two is particularly suitable for movement joints in structural glazing systems, curtain walls, glazed façades and other façade constructions, as well as highly elastic movement joints in building and glazing structures. It performs equally well for perimeter sealing around façades, frames, panels, windows and prefabricated elements, and for top and heel sealing of single, insulating and safety glass. It can also be used to seal PMMA and polycarbonate sheet materials without causing stress cracking or crazing, and for the repair and renovation of damaged silicone joints in building, glazing and façade applications.
