The U.K. branch of ThreeBond Europe SaS (Milton Keynes, U.K.) has developed TB 1530, a one-part, nonsolvent elastic adhesive, the main component of which is a silyl-based polymer that reportedly reacts rapidly upon exposure to moisture in the air and cures to form a toughened elastomer with time. It contains no solvents or plasticizers, is nonstaining and can be painted. It is weather-resistant, has high adhesion strength to most substrates without the need for primer, and features low-odor and chemistry that contains no isocyanates. The adhesive is said to be highly elastic with good peel strength and impact/vibration resistance, and does not require UV or thermal curing facilities.
