The correct cement for


Recommended Posts

Josh, that's a loaded question as everyone will have their favorites. Personally, I like to use liquid glues such as Bondene, Tamiya, or one that's available online from Micro Mark called "Same Stuff". It was called that as they used to sell Ambroid Pro Weld, but that brand is no longer.

Others like to use regular tube glue, but I'm not a big fan of this because.............

1) Drying time
2) Messiness in applying it
3) The glue can continue to "eat" into the plastic years after applying it.

Others can chime in, but one should have a variety of glues on hand for different tasks. White glue or 5 min epoxy for putting in windows, or attaching outside body parts.

Super glues for general construction.
"Semi Liquid Glue" (Testors) when you need something to hold, but don't want the too thick tube glue, or the pure liquid stuff which is best applied with some kind of applicator.

Hope all this helps!

Model cement is essentially a "cold weld" (a term for the chemical-reaction between the adhesive and the parts it's bonding-together . In other words , the cement ( glue , et al. ) does indeed melt the styrene (the cold-weld) , and then catalyses ( dries ) in "x" timeframe .

"Super Glue" ( et al. ) works differently ; there's no melting of the surfaces it comes in-contact with . These glues are acrylic ( "CA" = Cyanoacrylate )  ; their 'setup' time varies ( e.g. , "Quick Set" , etc. ).

With all glues which are indicated for use in bonding polystrene , the adage is "A little bit is too much." . In other words , don't apply more glue than necessary .

 

Personally , I favour Tamiya glue ( the orange lid liquid for general assemblies ; the green lid for gluing parts which are clamped or banded together )
