3m adesivos scotch-weld-polyurethane-reactive-adhesive-te200
The document is a Portuguese‑language technical data sheet for 3M™ Scotch‑Weld™ Polyurethane Reactive Adhesive TE200, a single‑component, moisture‑cured hot‑melt adhesive designed for rapid‑set, long‑open‑time bonding of wood and a wide range of substrates (plastics, FRP, metal, glass). It details product characteristics (100 % solids, high‑strength, heat‑sensitive substrates), typical uncured and cured physical properties (viscosity, density, open time, handling strength, modulus, Shore D hardness), performance data on adhesion to various substrates (ABS, PMMA, aluminum, FRP, glass, PC, PS, PVC) and mechanical properties (elongation, tensile strength, peel adhesion). The sheet provides comprehensive application guidance, including surface‑preparation procedures for different materials, recommended dispensing equipment, temperature limits, curing behavior, cleaning methods, and safety precautions. Packaging options (10 fl oz cartridge, 2 kg bag, 5‑gal bucket, 55‑gal drum) with coverage estimates are listed, along with storage conditions, shelf life, warranty limitations, liability disclaimer, and ISO‑9001 quality statement. The content is aimed at industrial users who possess technical competence to evaluate and apply the adhesive safely and effectively.
Topics
Product Overview and Core Characteristics
Introduces TE200 as a single‑component, moisture‑cured polyurethane hot‑melt adhesive, highlighting its 100 % solids, high‑strength bonds, rapid strength gain, long open time, and suitability for wood and diverse substrates.
Typical Uncured and Cured Physical Properties
Lists measured viscosity (3 000 cP at 121 °C), density, open time (4 min), handling strength time (120 s), cured modulus (9 700 lb/in²), Shore D hardness (60), and other mechanical metrics under standard test methods.
Adhesion Performance Across Substrates
Provides quantitative peel‑load values for ABS, PMMA, FRP, PC, PVC, etc., and notes substrates where the adhesive is not recommended (e.g., untreated polyolefins, certain metals/glass under specific conditions).
Application and Handling Procedures
Details step‑by‑step guidance: surface cleaning, temperature limits, application temperature, open‑time constraints, bonding sequence, and cautions against using the adhesive on metal‑to‑metal or glass‑to‑glass without moisture transmission.
Surface‑Preparation Protocols for Different Materials
Specifies solvents (isopropanol, MEK), abrasive steps, and primer recommendations for plastics, FRP, rubber, aluminum, and glass, emphasizing removal of contaminants and drying before bonding.
Dispensing Equipment and Temperature Limits
States that only 3M‑approved hot‑melt dispensers may be used, lists compatible cartridge and bulk equipment, and warns against exceeding 275 °F (135 °C) during application.
Packaging Options, Coverage Estimates, and Shelf Life
Enumerates available container sizes (10 fl oz cartridge, 2 kg bag, 5‑gal bucket, 55‑gal drum), provides linear‑foot coverage per container, and outlines storage temperature (<120 °F) and shelf‑life (12 months for small packs, 6 months for larger bulk).
Safety, Warranty, and Regulatory Disclaimers
Summarizes safety precautions (heat‑resistant gloves, eye protection, ignition control), liability limits, warranty conditions, intended industrial‑only use, and ISO‑9001 quality system statement.
