I mpact Adhesives Cyanoacrylates are single component moisture curing adhesives which cure rapidly to form tough, durable, high performance bonds. Cyanoacrylates arc chosen for their versatility and ability to bond a wide variety of substrates including; metals, woods, ceramics, rubbers, plastics and textiles to name a few. The rapid bonding of parts ensures efficient production levels and accurate control of costs. We boast a range of cyanoacrylate adhesives few manufacturers can equal. The total range consists of over 300 different grades.

Cynanoacyylates

Product Range


At Impact Adhesives we segment our cyanoacrylates into three main categories identified by chemical type. These are Methyl, Ethyl and Specials (which includes Propyl, Butyl, Methoxyethyl and Allylester based cyanoacrylates). Within these three categories are adhesives to cover most industrial applications.

We understand, however, there are some applications for which the detailed grades will not be suitable. That is why we offer the number of grades we do. In such circumstances we recommend you contact our Technical Department who will be pleased to advise on the best adhesive to meet your application requirements.

METHYL CYANOACYLATES

Methyl cyanoacrylates are short molecular chained adhesives making them particularly suitable for metal to metal bonding and in some circumstances metal to rubber bonding. There are two main grades capable of satisfying most applications but other grades are available if required. In general, methyl cyanoacrylates exhibit excellent bonds between -300C to +100C. Higher temperature resistant grades are available.

501
is a low/medium viscosity product with good adhesion levels on most metals. The cure speed and general properties of the adhesive make it the most universal methyl cyanoacrylate within our range. Its easy flow properties mean it can be used straight from the bottle without the need for specialist application equipment whilst still maintaining your fast levels of production.

503
is our higher viscosity adhesive for application to more uneven surfaces yet retaining fast cure speeds. The viscosity allows for bridging tolerances of up to 0.2mm. The chemical make up of the adhesive provides good resistance to temperature, vibration and impact.

Application

ETHYL CYANOACRYLATES

Ethyl cyanoacrylates are the main type of instant adhesives used within industry. Impact Adhesives 600 Series can be used to form bonds on plastics, elastomers, metals and many other materials, both to themselves and to each other. The inherent inner elasticity of our ethyl grades ensures excellent durability and ageing characteristics, with an allowance for differential rates of expansion between dissimilar materials. Temperature resistance ranges between -300C and + 100C dependant on the grade and substrates being bonded.

601
is our very low viscosity adhesive (2mPas) exhibiting extremely quick cure speeds. It can be used for mating close fitting parts and for wicking into pre-assembled components. The rapid bonding characteristics of 601 enable high levels of production to be obtained cleanly and effectively.

609
ethyl cyanoacrylate has been designed specifically for bonding rubbers (elastomers) and plastics as well as being a good general purpose low viscosity adhesive. When used in conjunction with Impact Adhesive 841 Polyolefin Primer, difficult to bond substrates such as polypropylene, polyethylene and other polyolefin plastics can be successfully joined. (Please consult Technical Information Sheets 609 and 841 for full details).

613
low/medium viscosity fast curing adhesive is used primarily for bonding plastics and general materials. 613 is a compromise between 609 and 617 and is often used as an alternative to either of these grades where viscosity is critical.

617
is our standard high performance general purpose adhesive with a fast cure speed across a variety of materials. The medium viscosity of the adhesive means it is easily applied and can be used in most situations without the risk of over application leading to unsightly joints. 617 will bond wood, cork, foam, leather, paper, plastics, ceramics, metals and most other industrial and domestic materials.

627
medium viscosity adhesive offers excellent bonds whilst providing some gap filling capacity. The viscosity of 5OOmPas means that the adhesive can be applied to porous substrates with little risk of absorption which could lead to a reduction in bond strength.

631
is a medium/high viscosity adhesive ideal for bonding porous substrates such as wood where good gap filling is required and speed of cure is still important. When used in conjunction with an activator e.g. 831, 833 the adhesive can be made to bond porous substrates instantly whilst retaining incredible tensile shear strengths.

637
exhibits very high viscosity (20,000 mPas) allowing it to be applied to vertical surfaces with reduced risk of dripping. 637 will bond most materials including very porous substrates and, although it is very thick, it is still possible to apply it directly from the bottle.

Application
639
Gel is a thixotropic adhesive supplied in a tube for ease of application. The cure speed of the adhesive is slower than normal and allows for some repositioning of components. Speed of cure can be increased by using an Impact Adhesive Activator

643
is a high performance adhesive. It is rubber toughened and has been specially formulated to withstand high temperatures, (120C constant and up to 160C intermittent dependant on substrates). The high viscosity (3200 mPas) means gaps of up to 0.4mm can be bridged effectively. The rubber content in the adhesive allows for greater joint flexibility and allows for differential expansion of the bonded materials.

SPECIAL CYANOACRYLATES

Impact Adhesives 700 Series includes Propyl, Butyl, Methoxyethyl and Allylester. Modified ethyls and methyls are also included. Each chemical type offers different levels of performance, characteristics, advantages and benefits over one another, justifying inclusion in the range. Only by including all permutations can we provide you, the customer, with the level of service and performance you expect.

704
Tamper proof cyanoacrylate is a modified ethyl adhesive designed for temporary locking of components. Its blue colour means that any tampering of screws etc. can be easily identified. The low strength ensures that the component can be disassembled if required.

710
Butyl cyanoacrylate is a long molecular chain adhesive suitable for bonding sensitive plastics such as polystyrenes, polymethacylates and polycarbonates, which are prone to stress crazing. Impact Adhesives Butyl Cyanoacrylates exhibit extremely low exotherms and under the correct circumstances can be used in medical applications. USP approved grades are available on request and customers must contact our Technical Department before using such products for medical applications.

716
Low odour/low bloom grade adhesive is a methoxyethyl based product with a neutral and virtually unnoticeable odour. Because of the products' high molecular weight and resulting low odour, it is very user friendly and irritation of mucus membranes is almost excluded. 716 is also low bloom with no white lining apparent on cosmetically critical areas.

719
Low odour/low bloom is our higher viscosity version of 716 allowing the user better gap filling capability and slower curing, whilst remaining user friendly.

799
High temperature cyanoacrylate is an allylester based adhesive providing remarkable temperature resistance. Designed for bonding metals in the electronics industry, yet with many other potential applications where temporary temperature loadings of +200C are present, 799 can be used for applications previously unsuitable for cyanoacrylate adhesives.

ACTIVATORS

Activators At Impact Adhesives we offer a range of products to supplement our cyanoacrylate and anaerobic adhesives enabling our customers to use the adhesive more efficiently. Activators (or Accelerators) are solvent borne liquid products which enable both cyanoacrylate and anaerobic adhesives to cure more rapidly than normal. Unlike many adhesive manufacturers, we are able to offer a range of activators ideally suited to customer requirements.

801
Anaerobic activator promotes the speed of cure of our anaerobic products. 801 also promotes difficult to bond substrates including non-ferrous metals and some plastics. Using 801 or 803 (non aerosol version) at temperatures below 15C will aid the speed of cure.

831
Activator for cyanoacrylates is based on heptanes and acts quickly and effectively on most industrial materials. 831 is available in a variety of pack sizes to cover most eventualities.
