Technoform Adhesion Prime offers advancement in adhesion for windows, doors, curtain wall with thermal barriers 

Technoform Adhesion Prime enhances the adhesive properties of polyamide (PA) strips by modifying the thermal barrier surface. Thermal barriers with Adhesion Prime increase thermal performance for aluminum-framed windows, doors, curtain wall and other fenestration and façade systems. Systems with high thermal performance also help to improve condensation resistance and acoustic performance, and to maintain comfortable interiors for occupants near the façade. 

Saving fenestration product manufacturers time, labor and costs, Technoform Adhesion Prime allows glass or metal to be bonded directly onto PA. This technology offers the same high level of adhesion to sealants, without the need for chemical primers and without added steps to current best practices and processes. Simplifying the assembly helps reduce the quantity and cost of frame components, and the weight of the assembled structure.

“Adhesion Prime ensures a secure base for bonding any type of material with glue or silicone,” explained Technoform’s Bill Blazek. “It allows manufacturers the ability to bond glass or metal directly to PA without the use of fasteners, which are difficult to handle and often have poor thermal performance.”

Supporting energy-efficient building envelopes, Technoform Adhesion Prime creates a bond between the silicone adhesive and the PA thermal barrier’s surface that is strong enough to meet all the structural requirements of ASTM C1401 – Standard Guide for Structural Glazing Sealants. Structural sealant glazing (SSG) primarily provides structural support and attachment of glazing or other components to a window, curtain wall or other framing system.

Technoform Adhesion Prime modifies the thermal barrier surface by creating a layer of aluminum oxide (alumina) particles embedded in the PA surface. This new surface forms a solid alumina interlayer between the polymer and sealant. This “micro-aluminum profile” bonds to the PA surface. Since the aluminum oxide surface is non-continuous, its presence does not degrade the thermal properties of the polymer barrier and the PA remains fully recyclable.
