Abstract
The storable glass tube sealed on both sides contains the two components of a two-component adhesive and fibers or chips incorporated therein in separate sections which are in immediate contact, being located in said glass tube such that there are portions of both components present at as many as possible intersecting planes perpendicular to the longitudinal axis of said glass tube.
Claims17
A storable glass tube sealed on both ends and containing at least one portion each of compositions A and B, wherein:
- composition A comprises the first component of a 2-component adhesive that reacts by polyaddition and fibers and/or chips incorporated in said first component, which is viscous at room temperature;
- composition B comprises the second component of the 2-component adhesive and fibers and/or chips incorporated therein, which is viscous at room temperature and decreases in viscosity as the temperature increases;
- and wherein the at least one portion of composition A is in immediate 2-dimensional contact with the at least one portion of composition B in planes that are perpendicular to the longitudinal axes of the glass tube.
