THE PRESENTATION OF DELO ADHESIVES IN TOP WORLD FAMOUS ARCHITECTURES
MVRDV is a Dutch construction design company, famous in the world that any architect knows.
Crystal House in Amsterdam - Netherlands designed by MVRDV
The designs of MVRDV are breakthrough, luxurious, unique, and strange. Typically, the Crystal House in Amsterdam, the Netherlands. The facade of the building is built entirely of glass bricks. These bricks are bonded together with DELO PHOTOBOND 4468, PHOTOBOND 4497 , and PHOTOBOND GB368 adhesives.
| The building process of Crystal House – Designed by MVRDV |
The building was built with care and attention to detail. Glass tiles are carefully selected from Poesia, the world-famous glass tile manufacturer from Italy.
Bricks after grinding are tested for stress concentration by polarized light (Only those that meet the requirements as shown on the right will be used)
Each brick is thoroughly inspected. The most stringent requirement of bricks is that the flatness difference is not more than ±0.25mm. The bricks must be classified into 2 groups: Group A has a tolerance <+0.25mm and Group B has a tolerance> -0.25mm.
Check the flatness of 5 points on the tile surface
Adhesive requirements in these designs:
- Good adhesion to surfaces: glass/glass, glass/metal, glass/plastic, etc.
- Good resistance to weather, humid and harsh environments, does not change color when exposed to high temperatures or sunlight;
- Glue must be colorless and transparent;
- Compression strength > 17000 N.
To meet this requirement, MVRDV believes that it has chosen DELO glue for its projects. Includes DELO PHOTOBOND 4468, PHOTOBOND 4497, and PHOTOBOND GB368 adhesives.
PHOTOBOND adhesive is a product kind of modified acrylate glue, 1 component, cured under the effect of ultraviolet (UV) light with an extremely fast curing speed within 3 ~ 40 s.
DELO's solutions exceed customer expectations:

Surface treatment before dispensing: |
- Use DELOTHEN or DELOTHEN EP cleaning solution for glass surfaces. - 500ml spray bottle; |  |  |
Method of dispensing, curing glue:
Depending on the requirements of the application, customers can choose from the following ways to release the glue: | |
- Apply glue directly by hand: For simple applications, small joints, just need to apply glue by hand skillfully with 50ml glue bottle in the flat bottle, easy to operate. |  |
- Using DELOMAT 100 precision dosing pump system with large volume glue bottles (>1000ml), applied for designs that require high accuracy, small-sized glued parts. |  |
- The glue drying is extremely simple and fast, once you have selected the glue method and UV lamp model, the rest is just setting the time and intensity of UV irradiation. |

These DELO adhesive has now been applied at the first villa project in Ho Chi Minh City, Vietnam.
