One-part adhesive contains no solvents

Paul Boughton
Threebond's 1530 product is a one-part, non-solvent elastic adhesive whose main component is a silyl-based special polymer that reacts rapidly upon exposure to moisture in the air, curing to form a toughened elastomer. Since there are no solvents or plasticisers contained in the adhesive it shows excellent non-staining characteristics against all materials and can be painted.

It also provides excellent weather resistance, high adhesion strength to most substrates without the need for primer pre-treatment, and is environmentally friendly due to its low odour and non-isocyanate chemistry. This makes it suitable for multi-purpose bonding of metals (aluminium, steel, stainless steel and copper), plastics (polyacrylate, PPO, ABS, nylon, PC, FRP, PET, PPS, PBT and others), as well as many others such as wood, glass, canvas and rubbers - from chloroprene and EPDM to silicone.

TB1530 can also be used for sealing and potting of electronic/electrical assemblies in place of conventional RTV rubbers. However, as no low-molecular siloxanes are produced during curing, it will not corrode metals nor impair electrical contacts.

Threebond says that TB1530 is highly elastic with good peel strength, coupled to excellent impact/vibration resistance and does not require UV or thermal curing facilities. Its high initial adhesive strength means that no temporary jig fixing is required, with fixturing strength available immediately (following adhesive spread and a five-minute dwell time prior to assembly); handling strength comes within 20 minutes and full cure is achieved within 24 hours.
