Tweha PreFix X-tra

TWEHA PreFix X-tra is suitable for the pre-treatment of fiber cement bonded materials and stone-like materials with a porous surface.
The degree of density of a solid (the substrates to be bonded) allows water to penetrate between the solids of the material. In a porous material, as the word says, the water easily can find a way in the pores of the material.
Each material increases moisture to a greater or lesser extent. Tension due to its own weight and wind load is partly absorbed by the grain tension in the material of the panel. The remainder of this tension is absorbed by the water tension.

Normally this causes a slight change in shape, but in porous material it reacts different. Then the grains will slide over and even roll. This process gives water the opportunity to fill the available spaces. This process continues to repeat which ultimately will result in the development of a water film between the adhesive mass and the porous material until the adhesion of the glue joint collapses.
The surface enhancer TWEHA Prefix X-tra closes the pores on the surface of the substrate, distributes the tension over a larger surface, thus eliminating the above-described phenomenon, thus preventing the detachment of the bonding due to this described process.

TWEHA REVIEWS

Check out the most useful reviews written by our relations who are familiar with our expertise, technical support and TWEHA’s adhesive systems.

★★★★★

Due to the prevalent atmospheric conditions, in our country there were severe limitations to the installation of ventilated façade claddings during 6-8 months per year. With TWEHA’s primerless bonding system it is now possible to proceed with the installation all year round, thus offering a great benefit to our professional customers.
Beside the advantages of a primerless bonding system explained in the answer above, it was of great value to us to be able to count with the expertise and technical support of TWEHA which has enabled us to satisfy all the queries received from our professional customers.

I will certainly recommend TWEHA.

In 2019 we were looking at adding a new phenolic resin door style (HPL) to our cabinet line. The phenolic doors and panels are very heavy and our regular Polyurethane adhesives wouldn’t adhere to the surface of the material. TWEHA PanelMate was recommended by our paneling supplier and we are grateful for the recommendation!
We place a lot of faith in the adhesion properties of TWEHA PanelMate. Our panels are 12mm thick and there isn’t a lot of material for mechanical fasteners to attach to. We have to rely mostly on the adhesion of the TWEHA PanelMate in our factory and in our dealer’s installations. We find the drying time and adhesion work perfectly for our application.

TWEHA PanelMate’s testing document gave us great confidence. Great adhesion and durability outdoors. We have sold out a number of jobs in the past two years and have had no returns due to adhesion issues. We have also added TWEHA PanelMate as our adhesive of choice on our online ordering system and almost all of our dealers that order our phenolic door cabinetry order TWEHA PanelMate to use for their installations.

I had the opportunity to cooperate with Tweha company on a couple of projects, all praise, and recommendations. Very high-quality cooperation, and very high-quality products, helped in our work when it was most needed. Note – the products can be applied in conditions below 5 degrees, very important in our business, when it comes to sudden cold weather.

We’ve had no call-backs about installations anywhere.
That’s always good news in our book.
