Impact glue
open-in-new
<h2 id="properties">Properties</h2> <p>Impact glue has a high adhesive capacity, and is particularly failure-resistant compared to other non-reactive adhesives when applied correctly. It is typically applied in thin layers on both materials to be joined.<a class="footnote-ref" id="fnref:3" href="#fn:3"><sup>3</sup></a> Impact adhesives are used frequently with <a href="/facts/Laminate/o9EGJdwn">laminates</a>, such as in bonding <a href="/facts/Formica_(plastic)/fFYKnXY3">Formica</a> to countertops, and in <a href="/facts/Footwear/JgvYYCSS">footwear</a>, as in attaching outsoles to uppers. <a href="/facts/Natural_rubber/CbsjJxhY">Natural rubber</a> and <a href="/facts/Polychloroprene/MtLEdFvE">polychloroprene</a> (Neoprene) are the most commonly used contact adhesives. Both of these elastomers undergo <a href="/facts/Strain_crystallization/uYghg1Rr">strain crystallization</a>. </p><p>Contact adhesives must be applied to both surfaces and allowed some time to dry before the two surfaces are pushed together. Some contact adhesives require as long as 24 hours to dry completely before the surfaces are to be held together.<a class="footnote-ref" id="fnref:4" href="#fn:4"><sup>4</sup></a> Once the glue is ready, the surfaces are pushed together, and a permanent bond forms very quickly.<a class="footnote-ref" id="fnref:5" href="#fn:5"><sup>5</sup></a> As the bond forms immediately on contact, there is no need for <a href="/facts/Clamp_(tool)/YwDNJyFY">clamps</a>, as is the case with other adhesives.<a class="footnote-ref" id="fnref:6" href="#fn:6"><sup>6</sup></a> </p><p>Neoprene adhesives exist in two forms: the so-called "liquid" form suitable for horizontal surfaces, and the <a href="/facts/Thixotropy/SwtTPjlv">thixotropic</a> non-flowing "gel" intended for vertical or indoor installation.<a class="footnote-ref" id="fnref:7" href="#fn:7"><sup>7</sup></a> It may be packed in glue tubes for domestic use, in a pistol cartridge, or in a <a href="/facts/Steel_and_tin_cans/Mfopo4tz">can</a> for large quantities. </p> <h2 id="inhalation">Inhalation</h2> <p class="note">See also: <a href="/facts/Inhalant/usdwDeWh">Inhalant</a></p> <p><a href="/facts/Neoprene/MtLEdFvE">Neoprene</a> glue is a well known inhalant, with effects that range from an alcohol-like <a href="/facts/Substance_intoxication/LRnMxrKd">intoxication</a> and intense <a href="/facts/Euphoria/u4cnbWC4">euphoria</a> to vivid <a href="/facts/Hallucination/5eUvLcnp">hallucinations</a>, depending on the substance and dose. Some inhalant users are injured due to the harmful effects of the solvents or gases or due to other chemicals used in the products that they are inhaling. As with any recreational drug, users can be injured due to dangerous behavior while they are intoxicated, such as <a href="/facts/Driving_under_the_influence/n244VGfP">driving under the influence</a>. In some cases, users have died from <a href="/facts/Hypoxia_(medical)/JWV04G89">hypoxia</a> (lack of oxygen), <a href="/facts/Pneumonia/Jw0KquTA">pneumonia</a>, <a href="/facts/Cardiac_failure/7fckX3Jm">cardiac failure</a> or <a href="/facts/Cardiac_arrest/HIAm9AWX">arrest</a>,<a class="footnote-ref" id="fnref:8" href="#fn:8"><sup>8</sup></a> or aspiration of <a href="/facts/Vomit/R2vQkHqV">vomit</a>. <a href="/facts/Brain_damage/70hWCEhs">Brain damage</a> is typically seen with chronic long-term use of solvents as opposed to short-term exposure.<a class="footnote-ref" id="fnref:9" href="#fn:9"><sup>9</sup></a> </p><p>While legal when used as intended, in England, Scotland, and Wales it illegal to sell inhalants, including solvent glues, to persons likely to use them as an intoxicant.<a class="footnote-ref" id="fnref:10" href="#fn:10"><sup>10</sup></a> As of 2017, thirty-seven US states impose criminal penalties on some combination of sale, possession or recreational use of various inhalants. In 15 of these states, such laws apply only to persons under the age of 18.<a class="footnote-ref" id="fnref:11" href="#fn:11"><sup>11</sup></a> </p> <h2 id="safety">Safety</h2> <p>Most neoprene glues contain volatile <a href="/facts/Solvents/LoMPMz8S">solvents</a>, and the hazards imparted by these solvents must be indicated on the container.<a class="footnote-ref" id="fnref:12" href="#fn:12"><sup>12</sup></a> <a href="/facts/Aerosol/X1jXFLp2">Aerosol</a> applications of solvent-containing adhesives are typically more hazardous than liquid or gel forms of the same, though all forms of contact glue are recommended for use only in well-ventilated areas and away from sources of ignition.<a class="footnote-ref" id="fnref:13" href="#fn:13"><sup>13</sup></a> </p> <h2 id="bibliography">Bibliography</h2> <ul><li>Ebnesajjad, Sina (2010).
