Product Description
LORD 7545-B Curative is the Part 2 curative for LORD 7545-A/B equal-mix urethane adhesive systems. The off-white or black paste has a typical Brookfield viscosity of 230,000 to 650,000 cP at 77 deg F (25 deg C) and mixes with LORD 7545-A resin at 1:1 by volume or 1:0.87 by weight. The A/B configuration provides a typical working time of 3 to 5 minutes and reaches handling strength in 30 minutes at 75 deg F (24 deg C). It can be applied through handheld cartridges or automatic meter/mix/dispense equipment as part of a non-sag system for vertical or overhead placement. LORD 7545-B is a curative component, not a standalone adhesive.
