The document is a technical data sheet for 3M™ Scotch‑Weld™ PR100, an instant cyanoacrylate adhesive formulated for bonding plastics and rubber. It outlines the product’s purpose, recommended substrates (e.g., PVC, EPDM, ABS, nylon, Santoprene, Viton®), and key performance claims. Detailed uncured properties (color, base, appearance, density 1.06 g/ml, viscosity 80‑120 cP, handling resistance 10‑30 s, full cure 24 h) and cured properties (temperature resistance –50 °C to 82 °C, gap‑fill 0.05 mm, tensile strength 4,900 psi, shear strength 3,100 psi) are presented. The sheet provides surface‑preparation recommendations, step‑by‑step usage instructions, curing behavior, and post‑cure performance limits. Storage guidance (short‑term <30 days at 16‑27 °C, long‑term ≤4 °C) and a 12‑month shelf life are specified. Safety notes direct users to the product’s safety data sheet, and extensive legal disclaimer language clarifies that 3M offers no warranties and limits liability to repair, replacement, or refund. Contact information for 3M Brazil technical support is included.
