1: 1 Epoxy Structural Adhesive for Vehicle Panel Bonding

Product Description

Product Description

HY412 Two-component Panel Bonding Adhesive 

HY412 is a 1:1 ratio, two-component structural epoxy adhesive designed specifically for industrial applications requiring high strength, durability, and processing reliability.
Provides a continuous bond and seals weld and rivet bonded areas against corrosion.Designed to meet specific strength requirements for outer sheet metal panel replacement; panel bonding adhesive is typically used in conjunction with welding, rivets or hem flange joints. 

Product Feature

Core Features and Technical Specifications

Exceptional Mechanical Properties and Structural Strength

1,Shear Strength:Up to 20 MPa; effectively replaces welding, riveting, or mechanical fastening to facilitate lightweight design. 

2,Peel Strength:Features an exceptionally tough formulation capable of withstanding dynamic loads and impacts, making it suitable for bonding substrates with differing coefficients of thermal expansion. 

3,Durability: Resistant to fatigue and creep, maintaining stable performance even under prolonged vibration environments.
