    Polyetheylene to Polycarbonate - Adhesive

    I was thinking the same thing. The requirement of being clear with low application temperature limits the options. Tom Quinn Adherent Laboratories www.adherentlabs.com

    Polyetheylene to Polycarbonate - Adhesive

    Much depends on the application. How much bond strength do you need? Low/high temp resistance? Solvent resistance? Are the substrates thin films, sheets? How do you test for bond strength? Will you be making a thousand units/minute? Hand application? Tom Quinn Adherent Laboratories...

    Bonding Nylon 11 to Butyl Rubber

    I passed this on to one of my colleagues at Adherent who has more experience in this area than I. Here are his comments: "A couple of thoughts. For the butyl try a structural 2 part acrylic like the Permabond TA4200 series or 3M also has a number of these. The other thought is to switch from...

    Adhesive for bonding Polypropylene sheets

    A lot is going to depend on what kind of tolerance you can accept with the spacing after reactivation. Much will also depend on the bond requirements. Do you have peel strength requirements? Heat resistance? Solvent/water resistance? How much flexibility do you need? How many layers...

    Looking for Sticky Gel

    These are typically blends of S(EB)S block copolymer rubbers and oil. The surface tack is increased by adding a high Tg tackifier. I would expect a "glue-dot" like composition, which would contain perhaps 20-30% tackifier, would have too much adhesion for your application. You'd likely need...

    Adhesive to bond Tyvek desiccant pouch to steal?

    Most HM PSA's will be soft enough at 100C that they'll creep without much stress. Waxy hot melts would have enough heat resistance to hold up at that temperature, but I'd worry about adhesion to Tyvek and metal. With most hot melts the kinds of things you do to make them adhere to non-porus...

    Primer systems and olefins

    Yes, this is confounding. It should work. Maybe the EAA is neutralized, or maybe it has a contaminant coating. Regards, Tom Quinn Adherent Laboratories www.adherentlabs.com

    Looking for help with an adhesive

    I believe the insect strips are often coated with very viscous polybutene or polyisobutylene. BASF makes them or you could find them via Goggle. Regards, Tom Quinn Adherent Laboratories www.adherentlabs.com

    Bonding Polycarbonate to EVA Foam

    Try a solvent or water based acrylic PSA. Or you could spray a hot melt PSA. Regards, Tom Quinn Adherent Laboratories www.adherentlabs.com

    Adhesive to bond Tyvek desiccant pouch to steal?

    HM PSA's are used a lot to seal Tyvek envelopes and they adhere well by virture of their softness and pressure sensitive character. However, their softness and pressure sensitivity work against you if the bond is under any stress or elevated temperatures. How do you want to apply the adhesive...

    Adhesive to bond High Pressure Laminate to Powdercoat (textured) steel

    Dave, You need to determine if you are having adhesive or cohesive failure. Is there adhesive residue on both substrates after failure at 150F? If so, you are having a heat resistance problem and need a higher Mw or x-linked adhesive. If one of the substrates is clean, you need to improve...

    Polypropylene Glue

    Hot melt glue sticks are readily available, easy to apply, and should adhere reasonably well to your PP. However, they may not remove as easily as you want. BTW, HM glue sticks are almost never PP based. PE and EVA are more common. There are varieties of "palletizing adheisves" that are used...
