Glue / Brush / Fluid


Glue:

The glue is no wood glue, which dries very hard, and no hobby glue. Our adhesive can look the same, but you can check the purchase by buying the 3 adhesives and allow them to dry together. Our glue is the most powerful and most flexible.

Note please, that the glue need to dry a bit before monting. So that about 1/3 of the adhesive surface is still white and 2/3 is transparent. (See please our manuals.)

Brush:

The hairs of the brush were coated prior to shipment with a water-soluble wax. Wash out the brush in handwarm water. 

Fluid / Remover:

We use for removing the old foam methylated spirits or alcohol. You may use often on the frame some stronger remover at own risk. If the old glue is enough flat and strong ist's possible to glue on this old glue at own risk.

Glue > How much do you need?

Audiofriends uses per 10 inch one bottle of 15 ml. glue. However if you have gaskets on you speaker, you can also mount these ones with our glue. You need then some moe glue. To be sure you have enough glue, and don't have an unplesant surprise we handel aprox:

- Till 2 x 8 inch = 1 x 15 ml.
- 2 x 10 inch = 1 or 2 x 15 ml.
- 2 x 12 inch = 2 x 15 ml.
- 2 x 15 inch = 3 x 15 ml.

- 4 x 4 inch = 1 or 2 x 15 ml.
- 8 x 3,5 inch = 1 or 2 x 15 ml.

Out of our 'frequently asked questions':

19. You want to know more about the type of glue we use
.
The glue is a part of the revision. For instance, if you use Bisontix or Bisonkit, you run the risk of the glue affecting the foam immediately or at a later stage. More importantly, not all glues have the properties this special glue has. The special glue resembles wood glue, but it is markedly different.
Both are water-based glues, but wood glue becomes a lot harder and shrinks a lot more.

Both characteristics make wood glue unsuitable for this purpose. The glue needs to follow the movements of the foam. Glue that is too hard will come off. If the glue shrinks too much on the joints between, for instance, cone and foam, it will pull the foam towards it.

The glue we provide is also very strong, a lot stronger than the form itself and it is a water-based glue. This glue is especially made for hanging surround rims, dust caps, etc. and it is used by virtually all professional refoaming companies.

Audiofriends has conducted extensive tests with various types of glue on difficult surfaces.
Naturally, we also tested the glue on loudspeaker units. In this case, a unit of the most sold speaker in the world, the Bose 301
.
Depending on the circumstances, it takes approximately 30 minutes for the glue to become strong enough to be handled safely.
After about 24 hours, the glue is so strong that the foam rips apart in case of heavy-handed removal. The glue will not come off. After extensive tests, glue B was chosen from a selection of four different glues.

The following has been taken into consideration (among other things):
1. Process ability
2. Force on various materials after 30 minutes of drying
3. Force on various materials after 24 hours of drying
