The adhesive manufacturer Henkel produces various Loctite instant adhesives – also known as Loctite superglues – each of which is suitable for a different application, for example due to the different viscosities of the adhesives.<\/p>\n\n

For some Loctite instant adhesives, Henkel has changed the formula to remove certain chemicals classified as hazardous in the GHS (Globally Harmonized System of Classification) from the formulation.<\/p>\n\n

Loctite superglue<\/h2>\n\n

Henkel offers one- or two-component instant adhesives and instant adhesive gels under the Loctite brand. Depending on their viscosity, these instant adhesives are suitable for bonding certain materials together or for filling and sealing gaps. <\/p>\n\n

Cyanoacrylate technology<\/h2>\n\n

Instant adhesives are generally based on so-called cyanoacrylate technology. Cyanoacrylate (CA) is a chemical compound that is used for the production of instant adhesives – also known as superglues or instant adhesives<\/strong> – due to its adhesive effect. This is why these adhesives are also called CA adhesives<\/strong>, especially in the industrial and commercial sector. <\/p>\n\n

There are both one-component cyanoacrylate adhesives<\/strong> and two-component cyanoacrylate adhesives<\/strong>. With the latter, the curing in particular can be influenced by the mixture. <\/p>\n\n

Another special feature among instant adhesives are instant adhesive gels<\/strong>, which are intended for use on vertical surfaces and for filling gaps where sagging or dripping would cause problems due to their high viscosity.<\/p>\n\n

Depending on the instant adhesive, the curing and fixing time<\/strong> may be longer or shorter. CA accelerators can be used to shorten the curing and fixing time. In general, it can be said that light-curing instant adhesives cure the fastest. <\/p>\n\n

Areas of application and materials to be bonded<\/h2>\n\n

Instant adhesives are used in almost all industries. These fast-bonding adhesives are used in the automotive industry, for example, but also in medical technology. <\/p>\n\n

With the exception of glass, instant adhesives are suitable for a wide range of materials<\/strong>. For certain plastics with low surface energy, Henkel’s Loctite SF 770 polyolefin primer is recommended for surface preparation, including the bonding of polyethylene, polypropylene, polytetrafluoroethylene (PTFE) and thermoplastic elastomers. <\/p>\n\n

Improved instant adhesives without the addition of HQ and MMBP<\/h2>\n\n

In view of the increasing regulation of ingredients in instant adhesives, Henkel has refrained from adding HQ (hydroquinone)<\/strong> and MMBP (2,2′-methylenebis-(4-methyl-6-tert-butylphenol))<\/strong> to the instant adhesives listed in the following table. However, traces of these substances may still be present in the adhesives due to common manufacturing processes and\/or certain raw material impurities. For this reason, Henkel has set the following specification values: <\/p>\n\n
