VMS Flexy 5k Black Thin Glue

What's the best technique for precise application of the glue?

Dispense a portion of photo-etch glue on a piece of styrene, glass or a metal sheet, never on cardboard as it will absorb your glue. Have a 10 cm long piece of straight brass or steel wire ready, its Ø 0.5-1 mm. The wire will act as your renewable glue applicator. Dip the tip of a brass or steel wire in the blob and then touch it to a PE part or the model itself. Bring the parts together. That's that! Now cut the tip of your applicator wire with your trusty modelling knife or better side cutters to start anew with a clean tip. Small parts can be held with tweezers and dipped in the blob without resorting to the wire. 

I have dispensed a portion of the glue as per instruction, how long till it becomes useless?

A blob of glue is good about 45 minutes after it was dispensed. It gets thicker overtime. For best results and to conserve your glue dispense smaller blobs to always have a small amount of fresh glue at your disposal. 

I have misaligned my PE part and want to reposition it!

Slide the tip of your hobby knife between the parts to separate them. Once the parts come apart scrub the remaining glue in the same manner, try sliding the tip between the glue remains and the part from the side, the glue will give in. PS may need some sanding after the procedure. You can also use VMS Debonder.

I want to create a stronger metal to metal joint!

To make a metal to metal joint stronger simply sand the more demanding parts such as tank skirts (schurzen) barrels etc. By doing so you will achieve the following:

• remove the patina,

• remove possible dip coatings some PE manufacturers apply over the frets,

• give the glue better adhesion thanks to the altered surface.

Use 600 - 1000 grade paper and sand only the spots that will accept the glue. Joints created this way are up to 50% stronger than smooth, not sanded metal which can be problematic if unprepared. When you sand your brass fret you will see the change in colour, it's a sign of a well prepared surface.

Please note: even apparently pristine frets are covered with some patina, it's natural for the brass to form a layer of it over time. If you can't see it it doesn't mean it's not there same goes for dip coatings.

There are problems with the joints I've created!

​

Fingerprints and any other residue don't help your cementing! Make sure you degrease surfaces and sand the more difficult metal parts if necessary to remove brass patina and/or dip coatings. Degreasing can be conducted with simple dish washing fluid for plastic parts. Metal can be degreased with dish washing fluid but you can also use more aggressive chemicals such as acetone which evaporates very quickly and requires no drying. We advise you degrease metal parts with VMS Styrene Cement (standard type) which is a solvent blend and degreases better than basic chemicals (pure acetone).

What's the shelf life of the glue?

​

Old formula (oval bottle, round bottle without pin in cap): Opened bottle can last 12-16 months and more (if stored in the fridge, opaque box). Unopened bottle will be good for 16-24 months and more, provided it's stored in temperature below 10 °C or lower (fridge, opaque box). Glue can be refrigerated but can't be frozen. Shelf life very much depends on usage, that is how often you open and use the glue so the figures given will vary. Storage in temperatures higher than 15 °C and sunlight will decrease the shelf life. 

New formula (round bottle with pin in cap): Opened bottle can last 12-24 months and more (if stored in the fridge, opaque box). Unopened bottle will be good for 24-36 months and more, provided it's stored in temperature below 10 °C or lower (fridge, opaque box). Glue can be refrigerated but can't be frozen. Shelf life very much depends on usage, that is how often you open and use the glue so the figures given will vary. Storage in temperatures higher than 15 °C and sunlight will decrease the shelf life. 

​

My glue bottle contents seem low?

​

Yes, that's no mistake, all bottles are filled at around 1/2 of their capacity. The amount of glue will last an average modeller a 1.5-2 years. After that time it's a advised to acquire a new bottle due to the glue ageing. Bottle contents is 20 gr.
