LOCTITE UK 8103 / LOCTITE UK 5400 is a solvent-free two-component adhesive, based on polyurethane. The resin part (component A) contains organic compounds with hydroxyl groups, the hardener (component B) is based on isocyanates.
By mixing both components in a weight ratio of 5 : 1 a hard elastic adhesive is formed through chemical reaction. After curing the product exhibits no measurable change in volume. As natural raw materials (from different cultivation areas) are used a variation in color between different batches is possible.
