Often, after mixing, it is difficult to extract ingredients from the polymer base due to their interactions with other ingredients such as carbon black.
Analysis of extracted ingredients may give erroneous results due to contamination by other ingredients from the compound. The carbon black components in the blend often interfere with spectral analysis methods because carbon black tends to absorb spectural frequencies, such as infrared.
Testing of bonded rubber-to-metal parts amplifies the problems two-fold. The bonding adhesive is also a multi-component polymeric blend, much like the rubber. Also involved are contaminants associated with the substrate. For example, a stamped steel insert may be contaminated with hydrocarbons. If the metal is porous, oil may bleed out of the metal grain over time and undermine a bond system. Or, if the oil is present initially, it may prevent adhesive wet-out, thus inhibiting adhesion to the substrate.Note de contenu : - Traditional analysis is lacking

ViscositéIndex. décimale : 668.3 Adhésifs et produits semblables Résumé : Through the blending of an ultra high-solids VAE emulsion with many of the commercially available aqueous polyurethane dispersions on the market today, adhesive compounders can create a new class of stable high-performance waterborne adhesives.
Depending on the urethane grade selected and the level incorporated in the blend, the performance properties of the ultra high-solids VAE emulsion can be dramatically enhanced in the areas of :
- cohesive strength
- adhesion (vinyl)
- heat sealability and
- crosslinker performanceNote de contenu : - EXPERIMENTAL : Blend preparation
- TEST CONDITIONS AND RESULTS AND DISCUSSION : Viscosity stability - Cloth-to-cloth peel strength - Vinyl-to-cloth peel strength - Creep resistance - Crosslinked cloth-to-cloth - Vinyl-plywood strengths
