Can the heat shrink tape primer expire?

Release date:2017-11-22 Author: Click:

一分彩The composition of 3PE heat shrinkable tape is composed of the main tape of heat shrinkable tape, solvent-free epoxy primer, fixing sheet, rubber strip, etc. At present, most of the pipelines in China use 3pe heat shrinkable tape or heat shrink sleeve .

In the 3PE anticorrosion system, the epoxy coating layer really plays the role of anticorrosion of steel pipes, and the outer heat-shrinkable tape plays a role of sealing protection.

Solvent-free epoxy primer is composed of two components, A and B. Mix A and B components evenly during construction. So what if the customer purchases the heat shrinkable tape product in advance, and the primer has expired during the project construction? Can it still be used? Generally, if the shelf life has just passed, then our manufacturer recommends that you can open a set of primer products to check whether they have dried up and condensed and whether the appearance is abnormal. If drying out has occurred, it is not recommended. You can re-purchase a separate epoxy primer from the original manufacturer. So as not to affect the overall anticorrosive effect. In addition, when storing the epoxy primer, it should be stored in a dry, dull warehouse, avoiding direct sunlight.

一分彩When applying solvent-free epoxy primer, we should ensure that the primer is evenly applied, and the width of the brush should be basically the same as the width of the heat shrink sleeve. Because the solvent-free epoxy coating has dual functions, it is both an anticorrosive coating and an adhesive. Therefore, the roughened area must be primed. Be sure to install a heat shrink sleeve when the primer is still wet to ensure good adhesion of the hot melt adhesive to the primer. Heat shrinkable tape

When painting, we try to paint the primer with a width slightly larger than the width of the heat shrinkable belt or heat shrinkable sleeve.
