Product Description
LOCTITE® ABLESTIK 970-1N1 is a blue, sag-resistant epoxy adhesive for general assembly applications across a wide range of substrates. The material provides a typical mixed viscosity of 60,400 mPa·s, a 90-minute work life at 25°C, and heat-cure options of 2 hours at 70°C or 30 minutes at 100°C. After curing for 2 hours at 70°C, typical aluminum-to-aluminum lap shear strength is 20.7 N/mm². The cured adhesive also has a typical Shore D hardness of 75 and a glass-transition temperature of 83°C.
Key features
- Sag-resistant consistency: A thixotropic index of 2.0 supports controlled placement before cure.
- Strong aluminum bonding: Typical aluminum-to-aluminum lap shear strength is 20.7 N/mm² after curing for 2 hours at 70°C.
- Flexible heat-cure options: Guideline schedules include 2 hours at 70°C or 30 minutes at 100°C.
Applications / Suitable for
- General assembly bonding
- Applications requiring sag-resistant adhesive placement
- Aluminum-to-aluminum bonding under the documented cure condition
