Subject: About Deletum

I ´m in Mexico and spent a day within the research facility where
Deletum was designed, i spoke with the Dr. Castaño about this matters
of antifouling and antivegetative coats, in principle it can be
incorporated into the product, a research protocol has to be elaborate
but thinks is not to difficult.

Perhaps you can be interested in meeting him, he will be attending a
conference in London from Nov. 1th. to 4th. I already advided him about
this possibility and is ok for him.

If you are interested let me know to send you coordinates and you can
arrange a meeting during next week.

Best regards

Adolfo Villalobos


Hi Adolfo,

Thank you for the update. I would love to meet Dr. Castaño at some point, but London in November will not be possible for me.

Please keep me up to date on Deletum, and I will keep my readers informed.

Deletum Update

I just received the following e-mail. I don't know Senor Villalobos, but I have no reason to doubt his veracity:

"Subject: Deletum 5000

"I comment you that Deletum 3000 is available now in Mexico as antigrafiti paint, problem of this product is its brighness (shinning?) that is not suitable for many applications where a shinning finish is not appreciated.

"Other problem that is being solved now is a proper way to retire the product once you decide , there is no commercial solvent able for the job, so they have been developing a kind of ´soft´sandblast that is another patent in the process around.

"Deletum 5000 is still in development stage (industrial) and will be available soon, it is opaque and more suitable for aplications in arquitecture, same properties different finish.

"I don´t know about antifouling properties due the fact that it has no antivegetative components and mixing some could be difficult (molecule sizes), but is something we can find out.

"Actually my company is starting some testings and selling in Spain, and there is a firm using the product in Mexico and USA.

"Hope some of your questions are satisficed.



My Reply:

"Hi Adolfo,

Thank you for the update on Deletum. I have passed your message on to my readers, so you may get some inquiries.

If you are looking for someone to test the antifouling qualities of Deletum, I would be interested.

Deletum 5000 Redux

[Update: Trying to find Deletum 5000? Look here]

I have been doing this blog for several months now, with a little sailing and a little local politics and a little personal stuff. I've done 50 odd posts so far.

The entry that has gotten by far the most hits and comments has been my post on Deletum 5000. I wrote about Deletum 5000 because I had seen this article in the Economist, and I woundered about the possible marine applications for this anti-grafitti paint that nothing sticks to.

Most of the commenters apparently can't read English, but hope that maybe the fact that I've commented on this Deletum 5000 means I've got some for sale. Turns out that my Deletum 5000 post is number 2 on the Google search for 'Deletum 5000'. So this entry is just a shameless way to get a few more hits and maybe move up to number 1...

Deletum 5000

[Update: Looking for the source for Deletum? Look here]

I just read about a new paint called Deletum 5000. It contains nanometer scale silica particles that each have a water repellent and an oil repellent molecule attached to its surface. Normally these molecules repel each other, but the silica holds them together. As the paint dries, these water and oil repelling molecules are forced to the surface. The result is a paint to which nothing sticks. It was developed to foil graffiti. Oil and water based paints won't stick to it. I wonder how barnacles would do...
