[pianotech] adhesive for Vagias keytops

[Bill Costanzo]

I have also had mixed results with what they recommend. I don't care for
their procedure either. 

 

There is one water-dispersed contact adhesive that works really well.  3M
Fastbond Contact adhesive 30-NF

It comes in green and white, naturally you'll want the white.  I do a lot of
Vagias Keytops as well as Pianotek's German tops and have never had a failed
glue joint with this stuff.

I think it's as strong as solvent based CA, with all the benefits of a water
based product, i.e. easy clean up, no odor, etc. 

Here's my procedure:  

1.	Surface keys
2.	lay out tops upside down
3.	apply glue to key then Keytops then a second coat to the keys (I use
a 1" foam brush)
4.	let dry, a fan helps if it's humid, but generally like most water
based products it dries within half an hour.
5.	Assemble and apply clamping pressure to set the bond. I have a quick
release vise with large wooden jaws (cork lined) and do 2 keys at a time
which goes quickly.

 

Here's the technical stuff:

Greetings -

Has anyone had success with an adhesive for Vagias keytops (simulated ivory)
other than the water-based contact cement recommended?  I am not a fan of
contact cement, but if it is the only adhesive that will yield reliable
results with this material I will reluctantly go that route.

Any feedback will be appreciated...
