Sherwin-Williams announced a new RHF series of integrated Basecoat Stabilizer for the Ultra 7000 basecoat system.
I love the Ultra 7000 system it is very user friendly has great color matches and the standard stabilizer has no reactive reducer so the paint I mix up today I can use a week form now or a month from now. For "“better bite"” on urethane bumpers or increased chip resistance I have recommended that my customers put a capful of hardener in their base.
Digging into MSDS I see that the RHF integrated stabilizer has two diisocyanates that are going to give great bite. The trade off is you lose the indefinite pot life (it goes down to 8 hours). But they still recommend using a little hardener to improve chip resistance.
There are two little things I am wondering about in the product data sheets; they say the recoat time is 7 days. Yikes can that be right I always figured is 4 hours was a long time.
And the other thing is when doing multiple colors "“light colors dry faster than darker colors", really?
