Titebond glue.

[Derek Willis.]

About six or seven months ago, I bought an american gallon (4 Ltrs.) Titebond wood adhesive, I have used more than a third of it but, I find that now it dries pure white instead of clear, there is no loss of adhesion or strength as far as I can see, but what has happened?


Right off topic, why do I have to log on everyday, despite ticking the remember me box, it is tiresome to say the least?

The glue might have got cold in a shed perhaps? I think they have quite a comprehensive website which might help.

As for logging in, have you checked your browser settings for remembering passwords?
I use Seamonkey at home and firefox at work and can't recall the last time I had to login with either.

Does your browser remember passwords for other sites OK?

If you are using IE then I can't help you as wont use that browser.

Good Luck

I think it might be

My browser has about 7 cookies set by this forum but the above looks most likely.

If its drying white its due to cold weather, you may be lucky and find the bottle is OK it just does not dry properly below about 10degC. If the whole bottle has got frosted then you are out of luck.

I keep mine indoors and just fill up one of their 8oz bottles as needed.

Just got a reply from Titebond, seems that all my suspicions are proven, TOO BLOODY COLD !!!!
Derek.

When the glue dries white, the temperature is too low. In an emulsion adhesive, the discrete particles of adhesive are suspended in water much as is fine sand in water. Upon drying the loss of water pulls the particles together with enough force to form a continuous adhesive film. If the drying temperature is below a critical point, the force of the water evaporation is inadequate to pull the particles into a continuous film, leaving discrete and unjoined particles in the dry film. This will make the dried film appear whiter than normal. This is known as “chalking” and the critical temperature is the “chalk temperature”. When it occurs, the glued joint loses strength. This can be corrected by raising the temperature of the air, glue or wood, or changing to a glue which does not chalk at the operating temperature.

I have since carried out an experiment, the glue was cold, that is a certainty, I applied some to the surface of a piece of timber in the workshop and left it there for a while, it started to go white around the edges, I then brought it into the home environment , about 70Deg. F. then it dried out clear to leave a surface that I would have expected in the first place.
Seems to me that my glue is alright, but as someone said previously, keep it indoors!!!!!!
