    Welcome to Kim Chemistry Q & A, where you can learn about Kim chemical consumption or questions of R & D industry, if you have any question, please contact us, we will answer your questions as soon as possible.

    How to stick to instant adhesive ?

    1.      Anchor hook principle:Fill the glue A over the two,the glue combines with water in the air and turn harden.

    2.      Polymeric surface affinity: Cation anionic polymerization,some material has good affinity with water.

    Is it the more viscosity,the faster the adhesive ?

    No. More thick viscosity slower speed, because increased consistency must add a thickener, and then the speed will affect the tackifier.

    Why albino?

    Lively glue molecules, scattered around the place before the glue solidified , causing bleaching.

    If instant glue points up, is the volume the same after hardening ?

    As the case may be, the faster solidification, the less damage. Not more than 0.1% maximum loss.

    Why the low whitening light scent?

    The longer molecular chain, the molecule is not easy to shed lively, so more tasteless, less bleaching.

    Why are there different consistency ?

    Usually in response to the size of the gap material, and construction conditions depending on the customer.

    Why use A carboxyl but not B carboxyl?

    A carboxy is market mainstream products, the speed, strength and taste are good performance than B carboxyl .

    May methyl stick stainless steel it ?

    Yes. All the metal can use B carboxyl products. B carboxyl is good affinity for the metal than A carboxyl,

    Is it the rougher on the surface the better stick ?

    Generally yes. But there is a special surface treatment material exceptions or special column.

    The PE is used in the bottle of glue,is it because of its bad affinity ?

    Yes.PE is a high-density material, airtight.But AL is better than PE.

    What is the relationship between the albino and glue ?

    The faster ,the weaker albino.

    What’s the reasons of why the speed of glue trun slowly ?

    Environment, materials, operating practices,and the customer's own requirements Etc.

    Why glue shelf life shorter?

    Poor storage conditions , direct sunlight , long-term exposure to air , foreign body invasion.

    What’s the reason of glue strength deterioration ?

    1. Material change ,supplier change.

    2 Material size, shape change.

    3 Operating environment changes (such as seasonal changes).

    4 Paste incomplete, poor adaptation.

    The use of instant glue?

    55 ~ 80.

    What’s the best storage conditions of glue ?

    Low temperature (10~15), dry, out of direct sunlight.

    What’s the standard test environment ?

    No uniform standards.Our R & D is a constant temperature 25 , humidity 70 to 80%.

    The standard of S.G.S/ASTM/EN ?

    At present, we have SGS / ASTM / EN proof, (ASTM F963-96a, European regulations for the EN-71).

    Does the glue has a boiling point ?

    Instant glue can not be measured boiling point at 1 atmospheric pressure , because it will be harden, it can be mearured at the atmospheric pressure 6mmHg under 65 .

    The specific gravity in 20 ?

    Generally speaking,the proportion of instant glue is almost the same as water.

    What’s the flash point ?

    When the glue turn flash point in the TDS, experiencing fire may burn, but does not spontaneous combustion.

    What’s the dielectric ?

    The higher the number, the better represent the conductivity.

    What’s the oftening point ?

    The temperaturer displayed on the TDS of instant glue,which makes the curing glue turn to iquid state and can’t stick. In the room temperature, the glue will be re-curing, but its adhesion will be reduced.

    Does it has international common NO. ?

    Any chemical res has its own NO.

    How to remove instant glue ?

    To remove the instant glue with acetone.
