- Porous Metal & MIM : DigInfo DigInfo - movie.diginfo.tv Using their MIM, Metal Injection Modeling process, Taisei Kogyo is making a new type of porous metal which allows for the control of pore size to as small as 1 micro meter. In the MIM process metal powder is mixed with space holder agents and binder elements to create the porous structure. Specific agents and binder elements, which are removed during the third stage of the MIM process, are used to create different chemical reactions and make different porous metals. Many types of metals can be used in this process such as Titanium, Steel and Copper with a wide variety of applications such as air bearing systems, and systems that distribute heat well such as the body of space ships and air conditioning systems.

- Non skid tape external or porous application This video from NonSlip Tapes LLC will ensure that you receive the correct advice for applying our non skid tape onto a porous surface. Once these simple instructions are followed you will have a durable and effective surface. The surface prior to application must be at least 50°F, clean and dry, if the temperature is lower one should use our bolt down anti slip plates. For adhering onto a porous surface such as wood, concrete or stone we recommend our porous surface primer. The porous surface primer should be brushed onto the surface as if it was a clear paint, cover the entire area where the non skid tape is to be applied, only enough to seal the area is required. The primer needs to dry, this should take no longer than 10 minutes in warm weather and no more than 20 in cooler conditions, once ready the primer will feel dry to the touch. The primer also has the added ability of acting as a keying agent to aid adhesion. Remove the backing paper lining the adhesive and press the adhesive base firmly onto the surface. Apply firm, even pressure this can be done by hand though we highly recommend our pressure roller. For high traffic areas or in situations where there is a lot of edge scuffing our edge fix sealer should be used. The edge fix sealer ensures that the edges are firmly fixed down. The edge fix sealer comes in a tube with a convenient fine nozzle for dispensing. Only a very small amount is required down the side, just enough to touch tape and surface. After ...

- Treatment for Damaged, Porous Hair w/ Amla I bet I'm not the only one who's ever needed a cure for heat damaged or super dry hair. In this video I show you how to use amla, powder, cocoa butter and almond oil treatment to combat those hair issues. Amla's pH makes it perfect for reinstating your natural curl, correcting a scalp issue or giving your oil a boost in the blinging shine department. I found that the combination of perfect pH and moisturizing, ultra fatty oils (like almond oil and cocoa butter) really boosts moisture retention. I wouldn't doubt that amla in this combination can help treat (maybe even correct) heat damage and porosity issues!

- Anti Slip Tape application video on external porous surface with Heskins primer This video provides you with the correct advice for applying our anti slip tape safety-grip onto a porous surface; it is a very simple procedure. We recommend the surface is above 10ºC, is not wet and is free from grease. For applying onto a porous surface such as wood, concrete or stone we recommend our H3506 primer. Brush the primer on as if it was paint, cover the entire area where the material is to be applied, only apply enough to seal the surface. The primer also acts like a keying agent providing extra bond if required. The primer requires some time to dry; this is only minimal, in warm conditions a maximum of 10 minutes, in colder conditions no more than 20 minutes. You can easily tell when the primer has set; it should be dry to the touch. Remove the paper backing liner, press down onto the surface. Once applied we recommend firm even pressure; this can be down by hand or with the use of a seam roller which Heskins can supply at a low cost. For high traffic areas or to be applied where there could be a lot of edge scuffing we recommend the use of our H3502 edge fix, this material is a compound that helps to prevent any edge failure. The tube is similar to a tooth paste dispenser. Simply apply a very small amount down the edge of the anti slip tape safety-grip, it should touch both the anti slip tape safety-grip and the surface, only a very small amount is required! Once applied it sets within a short period of time leaving behind an almost invisible edge ...
