LOCTITE CAT 15 LV
Harmonization Code : 8529.90 | Parts solely or principally used for TV, radio, and transmission

Main features
- Low-Viscosity Epoxy Hardener
- 120-Minute Working Time
- Rigid/Semi-Rigid/Flexible Epoxy Systems
Product Description
LOCTITE® CAT 15LV™ is a low-viscosity epoxy hardener specifically formulated for use with LOCTITE ABLESTIK® 45LV epoxy resin systems. The hardener enables the formulation of rigid, semi-rigid or flexible adhesive systems depending on the resin-to-hardener ratio used. It provides room-temperature or accelerated heat curing, excellent adhesion to metals, glass and plastics, and is particularly effective for bonding dissimilar substrates. The system offers adjustable flexibility, good electrical insulation properties and dependable mechanical performance across a wide operating temperature range.
