Look beyond generic claims and check measurable residue performance and stability metrics. Important data includes binder content, viscosity range and test temperature, sieve residue, storage stability, particle size or distribution indicators, and breaking or set time guidance. For rubber enriched products, review elastic recovery, elongation or flexibility indicators, crack bridging performance, and adhesion results on relevant substrates. Also check curing time recommendations, temperature limits, compatibility guidance, and shelf life. If the PDF does not show test methods or acceptance criteria, treat it as marketing and request a full COA and independent test data.
