Elimină necesitatea utilizării șuruburilor sau a niturilor, permițând panourilor să păstreze un aspect arhitectural curat și fără îmbinări vizibile.
Ghid introductiv TWEHA #1
Special surface primer for low surface energy bonding surfaces on façade panels
TWEHA Primer #1 este un produs de pretratare a suprafețelor, special conceput pentru fața de lipire a panourilor de fațadă și a altor substraturi, în cazul cărora acoperirile, finisajele sau alte tratamente de suprafață pot determina o energie superficială relativ scăzută și, în consecință, o aderență directă insuficientă.
Panourile moderne pentru fațade sunt disponibile cu o varietate din ce în ce mai mare de acoperiri, finisaje de protecție și tratamente de suprafață aplicate în fabrică. Deși aceste straturi pot oferi proprietăți decorative sau de protecție excelente, caracteristicile lor de suprafață pot afecta negativ umectarea și aderența unui adeziv.
Grundul TWEHA #1 creează o interfață de lipire stabilă și uniformă între aceste suprafețe critice și adezivul TWEHA, îmbunătățind condițiile necesare pentru obținerea unei legături adezive durabile.
TWEHA Primer #1 must always be considered as part of the complete bonding interface:
façade panel → coating / surface treatment → TWEHA Primer #1 → TWEHA adhesive
The durability of the final adhesive connection therefore depends not only on the adhesion of TWEHA Primer #1 and the TWEHA adhesive, but also on the cohesive strength of the coating or surface layer and its adhesion to the underlying façade panel.
TWEHA Primer #1 cannot compensate for a coating, finish or surface treatment that itself has insufficient cohesive strength or insufficient adhesion to the underlying panel.
Before application, the bonding surface must be dry, clean and free from dust, grease and other contamination. Surface preparation and application of TWEHA Primer #1 must be carried out in accordance with the applicable TWEHA Instructions for Use.
Because coatings and surface treatments can vary significantly in chemical composition, surface energy and adhesion to the underlying substrate, the use of TWEHA Primer #1 does not automatically guarantee durable adhesion.
The complete combination of:
panel + surface treatment/coating + TWEHA Primer #1 + TWEHA adhesive
must always be verified by an appropriate adhesion and durability test before approval for use in a bonded façade application.
Always refer to the applicable TWEHA Technical Data Sheet, Instructions for Use and the current list of Tested & Approved substrates

TWEHA Primer #1 improves the bonding conditions of difficult or low surface energy panel surfaces:
01
Developed for Façade Panels
Specifically developed for the bonding side of panels used in professional façade and cladding applications with TWEHA Bonding Systems.
02
Suitable for Selected Coated Surfaces
Designed for selected coated and surface-treated substrates, including low-surface-energy surfaces.
03
Improved Adhesive Interface
Creates a smooth and consistent bonding surface while promoting improved wetting by the adhesive.
04
Controlled Intermediate Layer
Forms a controlled layer between the coating and adhesive where direct primerless adhesion cannot be demonstrated.
05
Economical and Tested Application
Easy and economical to apply, enabling the use of certain coated surfaces where durable adhesion has been demonstrated through testing.
TWEHA Primer #1 is particularly suitable for:
TWEHA Primer #1 is particularly suitable for the bonding side of coated façade panels, and for façade panels with low surface energy finishes, factory-applied coatings and protective surface treatments. It performs well on coated metal façade panels, coated aluminum composite panels, and coated ceramic or mineral-based panels where specifically tested. It is designed for surfaces where direct adhesion with a TWEHA adhesive has proven insufficient, or where an adhesion test indicates that additional surface treatment is required, as well as other difficult or critical panel surfaces following TWEHA assessment. It is used in combination with TWEHA PanelMate, StoneMate, GlassMate or MetalMate where specified.

Primer #1 is intended for selected low-surface-energy panel backsides where additional adhesion improvement is required.
No. Primer #1 should only be used when specified by TWEHA or when testing confirms that additional surface treatment is necessary.
Yes. It modifies the bonding interface to improve adhesion on compatible low-energy surfaces.
No. The bonding surface must first be completely dry, clean and free from dust and grease.
Panel coatings, resins, finishes and production batches can vary and may significantly influence long-term adhesion.
Mai eficient, mai economic
În comparație cu sistemele tradiționale de fixare mecanică, sistemele de lipire TWEHA pot reduce costurile de instalare cu până la 40%.
Instalarea mai rapidă, numărul redus de componente și lipsa elementelor de fixare vizibile oferă avantaje atât din punct de vedere economic, cât și estetic.
