Features & Benefits
- Product Highlights
- TRAPYLEN® 691 is a specially developed low chlorinated polypropylene. It has outstanding affinity to polyolefinic plastics such as polypropylene, PP-modified EPDM thermoplastic rubbers and to polyethylene.
- TRAPYLEN® 691 was mainly developed for PE-coatings. It can be used directly as binder or after effective dilution, as primer. The cured film is fairly soft.
Applications & Uses
- Markets
- Applications
- Uses: TRAPYLEN® 691 is used either as a straight primer or as an adhesion promoter for base coats and pigmented primers. Its principal use is in paintings/coatings for molded parts in the automotive industry, preferably for interior panels.
- Application: Using TRAPYLEN® 691 as a primer dilute the solution with toluene to max. 10% solids. This primer can be applied by spraying, dipping, brushing or printing.
- Drying conditions: 30 s at 80 °C, residual quantity of resin about 3 - 4 g/m². When using TRAPYLEN®691 as adhesion promoter in base coats/pigmented primers, the compatibility of the system must be checked. The resulting base coat can be applied by spraying, dipping, brushing or printing if the system allows it. Drying conditions: Usually 30 min at 80 °C, residual quantity about 20 g/m².
