Por aquí comentan algo: http://www.paideianet.com.ar/pegat_padres.htm Dogon limita el uso de mayúsculas, significan que el que escribe está levantando el tono de voz Edit: "The original Eastman formula was not FDA approved for medical use, however, because of a tendency to cause skin irritation and to generate heat. In 1998 the FDA approved 2-octyl cyanoacrylate for use in closing wounds and surgical incisions. Closure Medical have developed medical cyanoacrylates such as Dermabond, Sooth-N-Seal and Band-Aid Liquid Adhesive Bandage." "Cyanoacrylates bond skin and eyes in seconds. Studies have shown that methyl-2-cyanoacrylate (SuperGlue and KrazyGlue) degrade fairly rapidly upon contact with living tissue. This leads to the release of formaldehyde and a toxic response. 2-octyl cyanoacrylate degrades much more slowly due to its longer organic backbone which slows the degradation of the adhesive enough to remain below the threshold of tissue toxicity. Due to these toxicity issues, 2-octyl-cyanoacrylate is used for sutures." Vamos que yo no usaría el bote de Superglue que anda por casa |

Después de más de ¡¡¡2 años!!! (cómo pasa el tiempo, snif  )retomo este hilo para preguntar a los químicos en la sala: a parte de calor, al pegar dos superficies (depende de las que sean) también se desprende algún gas, porque canta que te mueres. Mi pregunta es: ya que el pegamento es Cianoacrilato, ¿puede ser que uno de los subproductos de la reacción sea el cianuro de hidrógeno? sé que es poca cantidad para que pase nada, pero no está de más saberlo...
