Production of polyurethanes or polyureas giving bubble-free moisture- hardened products is effected using anhydrous additives comprising e.g. graphite, microporous activated carbon or microporous molecular sieves |
摘要 |
<p>Additive used in production of moisture-hardenable urethane or urea group-containing compositions by reaction of polyisocyanates with compounds containing >=2 reactive hydrogen atoms is an anhydrous material. Additive used in production of moisture-hardenable urethane or urea group-containing compositions by reaction of polyisocyanates with compounds containing >=2 reactive hydrogen atoms is an anhydrous material comprising graphite, microporous activated carbon, a hydrocarbon molecular sieve, an amorphous, microporous silica gel, an aluminosilicate and/or a crystalline microporous molecular sieve based on metal oxides, metal phosphates or zeolites.</p> |
