  • Patent number: 5894071
    Abstract: Two-component adhesive-, sealing- or coating compositions are being described which are separately packed, and comprise the component A and the component D, whereby the component A is curing as soon as it gets in touch with water or the component D which contains the curing agent for the component A.The component D can be, or a component B containing an ingredient which is curing at the contact of water, or, possibly, at the contact with the component A, orthe component D can also be a mixture of solid matter and a volatile ingredient which is causing the cross-linking of the component A.The advantage of the novel two-component systems is that the component D is working as a curing agent for the component A, however, a surplus thereof is, or self-curing, or it does not leave a nuissance residue in the cured composition.
