The adhesive set High Tack and Prep M contains two tubes of Bostik High Tack adhesive and a container of Bostik primer prep M. This combination is required when fastening solid PVC. Due to the high initial adhesive bond, it is often unnecessary to use clamps or supports while the adhesive dries.
Bostik High Tack comes in a standard 290 ml tube and requires a caulking gun for application. The primer Prep M ensures a strong adhesive bond between the plastic and the surface below. Therefore, it is strongly recommended to pre-treat the plastic sheet with the primer before applying the adhesive. The white adhesive is easy to work with and dries evenly. After application; the adhesive remains flexible, so it can cope with the possible expansion of the bonded materials. Some materials can expand due to temperature differences. One tube allows you to cover 9 metres with the adhesive. After opening the adhesive has a shelf life of 12 months.
The use of Bostik primer Prep K is recommended when fastening aluminium composite with High Tack.
