TA430–TA4246, TA4810/TA4820 structural acrylate adhesives (including no-mix, for magnets and aluminum)

Country: United Kingdom · Model: TA430–TA4246 / TA4810 / TA4820

The structural acrylate adhesives TA430–TA4246, TA4810 and TA4820 cure at room temperature, with a fixture time from 15–30 s to 30–35 min, and bond metals, plastics, ferrites and composites. Shear strength reaches 33–35 MPa in the TA4246. Many grades bond slightly oily surfaces without a primer.

No-mix (adhesive + initiator): TA430, TA435, TA436 (with Initiator 43, fixture 1–3 min), TA437 (one-component, accelerated by Initiator 41), TA4246 (33–35 MPa)
1:1: TA4200/TA4210 (aluminum, 23–25 MPa), TA4202 (high peel), TA4204 (clear for plastics), TA4810/TA4820 (plastics and unprimed metals, 21–28 MPa)
Low-odor, non-flammable: TA452 (metals, 28–32 MPa), TA4522 (plastics)
For magnets, free of methacrylic acid: TA439, TA459, TA4590

Description

The series of modified (meth)acrylates combines high strength with impact toughness and tolerance to surface preparation. In aviation they are used for magnets in electric motors, brackets, wire harness holders and cabin equipment. In no-mix systems the adhesive is applied to one part and the initiator to the other. The TA436 with Initiator 43 gives working fixture in 1–3 minutes, shear strength on mild steel of 15–25 MPa, tensile 25 MPa, impact toughness 10–15 kJ/m² and dielectric strength 30–50 kV/mm. The TA430 and TA435 are intended for metals, ferrites and plastics, and the one-component TA437 is accelerated by Initiator 41. The two-component 1:1 systems in cartridges are the TA4200 and TA4210 for aluminum (23–25 MPa), the TA4202 with high peel resistance, the clear TA4204, and the TA4810 and TA4820 (21–28 MPa) for plastics and unprimed metals. The low-odor non-flammable TA452 (28–32 MPa) and TA4522 are convenient for storage. The TA439, TA459 and TA4590 contain no methacrylic acid, and the TA4230 is flame-retardant.

How to choose

First the method of application decides. The systems with an initiator, TA430, TA435 and TA436, need no dosing, and 1:1 cartridges are provided by the TA4200, TA4210 and TA4810/TA4820. For aluminum take the TA4200 or TA4210, for metal with high strength the TA4246 (33–35 MPa), and for magnets in sealed electric motors the TA439, TA459 or TA4590. The TA42xx grades are supplied mainly to Europe, the TA4810 and TA4820 to America, and the rest worldwide. If only seconds are needed on metal, see the cyanoacrylate 910.
