In Response To: MAS Epoxies Queation (Peter A Sarnosky)

I have been reading the responses to this particular post and can see there has been a few "unsubstantiated facts " given. Now those of us who are meer mortals look at these responses and scratch our heads.. Of course we are going to want further clarification...we truly do want to learn from those of you who have amassed wisdom beyond where many of us have traveled. After all, I thought that was the whole point of this bb, so we can all learn from each other. So,if a response to a post is only intended as an opportunity to dazzle us with incomplete information don`t bother. Please be prepared to spend the time to substantiate your statement with follow up reponses so that all can judge the merit of your claims. I personally have learned alot from this bb, and think it is the best one around.You are a knowledgable group of people, who are willing on the most part, to go the extra mile to help someone out. I want to thank all of you who spend time to moniter and to respond to many of the enquires.( sorry about the rambling !!! LOL ) So without further ado let us ask again ....

STATEMENT :>>>>>> "The colder the environment the more water vapor that will condense on the epoxy before it cures. Water and water vapor cause the epoxy and the epoxy/glass bond to cure weaker.

Question: >>>>>>>> What is the basis of the above statement? Water vapor will not condense on any surface unless it is colder than the humid air around it. It is generally true that more amine blush will form on a curing epoxy surface if it is cold and the humidity is high. Weaker cure ? STATEMENT : >>>>>>> IN GENERAL, the heat deflection temperature appears to be about 30 degrees above the cure temperature. So after curing at 40 degrees your boat will be soft for some period of time at 80 degrees (at most a week or so). Question : >>>>>>>> I have not used any epoxy to date that I have noticed soften , have you personally experinced this ? I know that System Three epoxy with Hardener #1 will cure hard after several days at 40F. If will further cure when the temperature is raised to 80F. It will NOT soften in the process.

What do you think ? Thanks for the time !
