Smooth-On Task

[golem95]

Has anyone tried the TASK range of smooth-on casting plastics? Is it as bubble free as smooth cast?

task depends alot on the weather, it does not cure well in the cold, and is very brittle now. It use to be the best there was but I ordered some earlier this year and they have changed the formula. It now breaks apart like stale peanut brittle.

which Task did you use? Task was designed as a professional series of plastics with a lot of ranges of properties... no plastic cures well in cold weather, we do all our experiments at 72F anything lower can change the moleculiar structure of the plastic... if you have any Q's about the task series, feel free to ask and if you Ben, need help understanding what might of happened in your experiment, I can see if I can trouble shoot it with you.

whats do you think is better overall then smooth-cast 305 or say task 2?

what application? How thick? Generally Task 2 has a compression strrength of 8300psi to SC 305 which is 4500psi as well as a tensile strength rating of 6650psi to SC 305 of 3000psi

Task takes longer to demold which means you need to be more aware of environmental conditions such as moisture and might be more brittle in thin-walled sections... I tend to like smooth-cast roto if I am going thin with the plastic...

I will be sloshing it in a mold to about 1/8" thickness

you're slush casting with Task?



I don't think it will work how you think



it has such a long cure time.

No no no, I havent tried either. Im asking which would be best for slush casting. Any opinions would be great

 

[beaker]

Again, I would say roto...

Again, I would say roto...

so is roto relatively air bubble free?

Beaker, do you work at Smooth-On?

yes

i like task 5, but it has a strong smell to it when casting and sanding it

A little off topic, I dont know why but I just had to lol at these 3 consecutive posts.



Back on topic, Link the three minute working time. Is that enough?
