Always on hand and easy to use: TESCON SPRIMER – the new spray-on primer from pro clima

Dried-out products in paint cans and the time-consuming cleaning of brushes are no longer a problem with the new TESCON SPRIMER.

There will generally be dust present anywhere that bonding primer is being applied. Primer liquids and brushes can easily become dirty. TESCON SPRIMER now provides a solution to these problems: this innovative primer is applied directly from a spray can, which means that it stays clean – and you don’t to worry about accidentally knocking over cans of primer or having them dry out either! This spray-on primer is ready to use in an instant, can be applied at precisely the right location thanks to the adjustable nozzle, and has the same application properties that you are familiar with from other pro clima bonding primers.

Application also possible at temperatures below zero Celsius

Simply shake the can forcefully a few times and you’re ready to start applying TESCON SPRIMER, even during frosty conditions. The bonding primer penetrates deep into the application surface and strengthens dusty subsurfaces or subsurfaces with insufficient load-bearing capacity. It is permitted for wood fibre underlay panels and other similarly absorbent subsurfaces to be still somewhat moist when the primer is sprayed on. Work can also be continued on these surfaces – for example, the TESCON VANA all-round adhesive tape or the adhesive sealing tapes for plaster in the CONTEGA family of products can be applied without any waiting time being necessary. However, TESCON SPRIMER must dry fully for it to achieve its final level of strength.

TESCON SPRIMER can be sprayed on at precisely the location where a reliable adhesive bond is to be created.

Focus on health issues

Installation technicians have often enquired to pro clima about a primer that could be applied from a spray can, reports Michael Förster, an Application Technology specialist at this Schwetzingen-based airtightness and windtightness specialist company: “It took a while to create a product to meet this need, as we wanted our new primer to be a lot better in terms of environmental friendliness and occupational health and safety than the spray-on primers that are already available on the market.”

“The advantage of spray-on primers is that they are significantly easier to work with than similar products in bottles. After all, you don’t need a brush and you can apply the product precisely where you need it by spraying it on. No lumps form in the primer either. I am delighted that pro clima is now able to offer TESCON SPRIMER – as I know that a lot of attention has been paid to sustainability and that the propellant is not harmful to my health or the health of my colleagues,” says the master carpenter and construction engineer Alexander Erny from Mannheim. He is also impressed by the ease of use of TESCON SPRIMER. The spray can is handy to carry around and is always on hand when he needs it.

TESCON SPRIMER is available from dealers in cans with volumes of 400 and 750 millilitres. Other new products from pro clima can be found at www.proclima.de

Why do adhesives stick?

Adhesive tapes: how do they work, what should they be able to do, and what can they do?

Carpenter uses adhesive tape to seal a building

Considerable lengths of various adhesive tapes are used when sealing buildings.
A carpenter can be seen here sticking the interior corners of a window when working on the interior of a fire station.

Adhesive tapes are used as bonding aids in a wide range of applications in the creation of airtight building envelopes. Several hundred metres of tape are often used on a single building! Adhesive tapes have become established as bonding agents for these applications (just as nails are the standard solution for timber structures). They have to fulfil their functions for a number of decades to ensure that the building in question fulfils the standards expected by the energy consultant and by the building client. This article provides an overview of adhesive technology and the key properties of adhesive tapes typically used in construction. Continue reading

Adhesive tape – how it works

pro clima clients ask – pro clima engineers answer

Adhesion in the area of airtightness and windtightness involves sticking parts together in a strong, permanent manner that would not stick together without the aid of adhesives. These adhesive joints should last as long as the building component itself! As well as offering high adhesive strength, these adhesive joints must also be able to accommodate typical movements in building components in line with the requirements of DIN 4108-7. The surface finish and so-called surface tension both have a decisive influence on the quality of adhesion. In order to stick materials to one another, adhesives are used that stick firmly to the subsurface (adhesion) and, at the same time, have sufficient internal strength (cohesion).

Various forces are at work in adhesive joints: cohesion, which holds the adhesive itself together, and adhesion, which holds the adhesive to the subsurface.
