The document is a preliminary technical data sheet (July 2021) for 3M™ Scotch‑Weld™ DP8600NS series two‑part acrylic structural adhesives (DP8610NS and DP8625NS). It describes the product as a low‑odor, high‑elongation, flexible adhesive suitable for bonding painted/coated metals, bare metals, plastics and composites, with ceramic beads to control bond‑line thickness. The sheet lists key features, uncured, mixed and cured physical properties (viscosity, density, mix ratio, work life, open time, cure times, hardness, tensile strength, shear strength, peel strength), and mechanical performance on various substrates. Environmental resistance data (heat, humidity, water, diesel, gasoline, salt water) and chemical compatibility notes are provided. Detailed dispensing and mixing guidance includes recommended nozzles, thixotropic index, pump equipment, and mixing procedures for both cartridge and bulk formats. Surface‑preparation protocols for painted/coated metals, bare metals, and plastics are outlined, along with recommended bond‑line thickness and cure temperature. Storage recommendations (≤80 °F, refrigeration optional) and a 12‑month shelf‑life are given. The document concludes with extensive safety, precautionary, warranty, and liability statements, emphasizing that the product is experimental, not yet commercialized, and that users must assess suitability, comply with regulations, and follow the SDS. The sheet also notes ISO 9001 quality compliance.
Topics
Product Overview and Core Benefits
Introduces the DP8600NS series as low‑odor, high‑elongation acrylic structural adhesives, highlighting flexibility, ceramic bead filler, and broad substrate compatibility.
Quantitative Physical and Mechanical Property Data
Presents uncured, mixed, and cured property tables (viscosity, density, mix ratio, work life, open time, cure times, hardness, tensile strength, shear strength, peel strength) for DP8610NS and DP8625NS across metals and plastics.
Environmental Resistance and Chemical Compatibility
Details performance after exposure to high temperature, humidity, water, diesel, gasoline, and salt water, and lists chemicals that degrade the adhesive (elevated‑temperature water, ketone solvents).
Dispensing, Mixing, and Application Procedures
Specifies recommended mixing nozzles, thixotropic index, pump equipment, open/working times, cure temperatures, bond‑line thickness, and step‑by‑step mixing and application instructions for both cartridge and bulk formats.
Surface Preparation and Substrate Compatibility
Provides cleaning and abrasion protocols for painted/coated metals, bare metals, and plastics, and notes low‑energy plastics where adhesion is limited.
Storage, Shelf Life, and Handling Precautions
Outlines recommended storage temperature, refrigeration benefits, 12‑month unopened shelf life, and safety warnings regarding solvents and ignition sources.
Legal Disclaimer, Warranty, and Liability Statements
Communicates that the product is experimental, not commercialized, and includes extensive liability, warranty, IP, and regulatory compliance notices.
