Primer - adhesion agent for epoxy resins | HP-UC
Primer, undercoating, adhesion agent for epoxy resins | HP-UC
HP-UC is a two component polyurethane primer / adhesion for applications with epoxy resins.Especially suitable for smooth, non absorptive substrates (many plastics, glass, metals, tiles,…)
Features & Benefits
- PUR primer for sticking or laminating on smooth surfaces
- High adhesion, suitable for all epoxy resins from HP-Textiles
- Ground coat (primer for carbon design)
- For spraying, manual application with paint-brush or roller is also possible
- Wax free, without styrene
Not suitable for porous, mineral substrates (concrete, screed,…), PE, PP, PTFE, silicones or elastomers.
Some of these plastics may have release agents on their surfaces (such as ABS). Theses release agents must be completely clean away - every trace has negative effects regarding adhesion!
