Contact adhesives (neoprene, rubber) are solutions of chloroprene (neoprene) or natural rubber in organic solvents. Bonding method: apply to both surfaces → wait 5–15 min (solvent evaporation) → press together. Bond strength 1–4 MPa. Elastic seam. Applications: footwear industry, furniture (upholstery), construction (insulation, flooring), automotive (trim, soundproofing). Water-based dispersions are an eco-friendly alternative to solvent-based (VOC-free). GOST 30535-97. Packaging: cans 1–20 L, buckets, barrels. Water-based contact adhesives (latex) are an eco-friendly alternative to solvent-based: odorless, non-flammable, VOC < 5 g/L. For furniture upholstery, footwear (upper seam), construction insulation. Bond strength 0.5–2 MPa. Storage: ≥5°C (do not freeze). Shelf life 12 months. Documentation: TDS, MSDS, certificate of conformity.
