TWEHA Primer #1

Special surface primer for low surface energy bonding surfaces on façade panels

TWEHA Primer #1 is a specially developed surface pre-treatment for the bonding side of façade panels and other substrates where coatings, finishes or other surface treatments may result in relatively low surface energy and consequently insufficient direct adhesion.
Modern façade panels are available with an increasing variety of coatings, protective finishes and factory-applied surface treatments. Although these layers may provide excellent decorative or protective properties, their surface characteristics can adversely affect the wetting and adhesion of an adhesive.

TWEHA Primer #1 creates a stable and consistent bonding interface between such critical surfaces and the TWEHA adhesive, improving the conditions required to achieve a durable adhesive connection.

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

Izstrādāts, lai nodrošinātu augstu veiktspēju un efektivitāti

Nav nepieciešama mehāniska nostiprināšana

Tādējādi vairs nav nepieciešams izmantot skrūves vai kniedes, kas ļauj paneļiem saglabāt tīru un viengabala arhitektonisko izskatu.

Brīvība dizainā

Paneļus var izgatavot plānākus un vieglākus, neiekļaujot tajos mehāniskās nostiprināšanas sistēmas.

Augsta izturība

Nodrošina izcilu saķeri, stiepes izturību un šķērsgriezuma izturību, garantējot ilgtermiņa konstrukcijas drošību.

Lietošana bez gruntējuma

Uz lielākās daļas pamatņu nav nepieciešami agresīvi līmes gruntskrāsojumi, tādējādi samazinot uzstādīšanas laiku un izmaksas.

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.
