Two Part Structural Adhesive 2140

Description

CTA 2140 is a structural methacrylate adhesive and a toughened flexibility. Once mixed through the nozzle this product cures to form a structural bond with high peel, fatigue and impact strength, even at low temperatures. This is a slower curing version of our structural methacrylate range (Please see  2105 or 2120 for faster set).

2140 is very versatile and can bond a wide variety of substrates with out the need for surface primers or conditioners.

CTA 2140 is a 1:1 ratio adhesive with an exothermic cure system. Designed for high strength bonding of metal and composite applications; bonding aluminium, titanium, stainless steel and engineered plastics. Often specified when bonding architectural cladding, metal fasteners to moulded composite parts, dissimilar materials for industrial fabrication, GRP in the marine and transportation industry and a range of other substrates within industry. Also great when bonding wood, granite, marble and Urethanes.

Two part structural adhesives technical information

A methyl methacrylate is the methyl ester of methacrylate acid. Its primary use is to manufacture a number of different plastics, but it is also the main ingredient in our range of adhesive products.

Methacrylate adhesives are supplied in a two part system that, when mixed, offer a controlled cure speed suited to the application. The cured adhesive can offer incredibly high tensile, shear and peel strength, whilst also resisting impact loads at both elevated and sub zero temperatures.

The unique chemistry of our two part structural adhesive 2140 is unrivalled in terms of convenience, ease of use and superior mechanical strength. Use for bonding engineered plastics, composites, steel, aluminium and other alloys.

How to apply two part structural adhesive 2140

Our two part structural adhesive 2140 has a 35 – 40 minute working life with a 70 – 80 minute fixture time. Before dispensing, ensure that surfaces are clean, dry and free of any dirt, dust and grease. For the best results, we recommend using CTA IPA Cleaner Degreaser.

• Use sufficient pressure over the whole surface at room temperature to ensure maximum adhesion to substrates.
• The ideal application temperature is between 15 – 25°C.
• Primers can increase the bond durability and surface tension for difficult to bond materials. We recommend CTA Primer or CTA UV Identifiable Primer to achieve the best results.
• Ensure uniform stress distribution.
