    Ammonia Vs NaOH

    I am messing my latex paint formulation. I know that some paints have ammonia in them to adjust the pH for a few reason, the only one that i have heard is to give the pigmented color depth. Is basifying (good word) the latex paint helpful (I am currently at pH 5.5, i am aiming for pH of 9) and...

    Vague Question: All about Cyanoacrylates (methyl or ethyl) I am looking for any and all info related to the manufacturing of Cyanoacrylate. As far as i have been told, and it makes sense to me, the majority of CA is made overseas in China, and receive additives and mixtures by other...

    Solution Vinyl Resins

    Does anyone know anything about the mess involving producers/manufacturers of solution vinyl resins. Dow used to make some, then a company in Brasil called Braskem was going to be making it, and now some company in China. Why are companies not producing this stuff anymore, is it dangerous...

    Waterproof adhesive for bonding acrylic to other plastics

    Depending on how strong of a bond you are looking for, there are glues that are a mix of polyisocyanates (strong)along with a primer and some butyl benzyl phtalate that is extremely strong and expands a bit as its drying.

    pH/Solvents/Indicators Help

    I have a very hydrophobic solvent solution and its current pH is around 7. I have been trying to use phnthln as an idicator (which the system accepts seeing as though it is 95% ethanol). The problem comes when trying to pH adjust the solution with 50/50 NaOH. This being dissolved in water...

    Water Based Adhesive

    Well, ironically, i am part of one of those (relatively) "big companies". We have solvent based glue, we have epoxy, we have hotmelts, we have cyanoacrylates. The only one that still proves elusive is some type of water formulation. Its better for the people using it, better on the...

    Water Based Adhesive

    Hello all, I am looking to create a new glue for my company and i/we would like it to be a water based glue. I will be gluing carbon arrow shafts to polyurethane vanes. My search started (slowly and discouragingly) with poly vinyl alcohol. It doesnt seem to have the tack and staying power...

    Solvent Based Adhesive Problems

    My apologies for being so vague. I am in industry so I have to be careful of what i put out there in the world (I like my job and i dont want to leave.) This is a marketed glue that you could pick up in most sports stores. Its used to attach 2 substrates, carbon and urethane. The problem...

    Solvent Based Adhesive Problems

    I am in what is considered an explosion proof building. I dont have any real instruments, i have no effective way to heat anything, large or small in quantity. I dont think that explosion proof is necessary but until i can fix that, i have to deal with it. Plenty of solvents but are always...

    solvent based gafted adhesive

    I cant tell whether u are buying your adhesive or whether u are trying to create your own. If you have access to the proper chemicals, try a solvent based adhesive (what i predominantly work with). One of the several solvents (big one is acetone, obviously) along with some form of a resin...

    MIBK v MEK

    There are many solvents to choose from (MEK, MIBK), does anyone know what kind of thickening or hardening effects one would have over the other. Dry time or viscosity or hydrophobic/hydrophilic qualities. Both are short hydrocarbons with ketones, seem similar to me

    Solvent Based Adhesive Problems

    I am currently working on a solvent based adhesive that consists of 3 solvents and 3 vinyl resins. In the warmer summer months, this adhesive could sit for 2 days and be thick enough for packaging. These cooler days (Michigan)the adhesive is having trouble setting up. Any suggestions? More...
