Discontinuation of Suhner Wet Tools

We were informed this morning that Suhner in Sweden has decided to discontinue their wet use tool line including their electric UXK-4 model and their pneumatic LXC-4 model. We no longer have any stock on either of these models.

The smaller 2 inch LXB-10 grinder has also been discontinued but we have 2 pieces currently in stock and the possiblity of 5 more available from Sweden from the remaining stock there.

These will be a first come, first served grinder so when they are sold out, that will be all that is available.

We still have plenty of stock on 2 inch backer pads for the LXB and will continue to carry 2 inch diamond disks and electrostatic disks for the existing LXB users and for the Alpha AIR-300 2 inch pneumatic grinder.

Changing the Structure of Glass

While many customers are familiar with the epoxy HXTAL and how it works to bond, laminate, repair, and replace glass you may not be as familiar with an often used companion to HXTAL, A-1100 Amino Silane.

“What is A-1100 Amino Silane?,” you may ask.

There are many different varieties of Amino Silanes on the market and they are all listed under adhesion promotors. They help various adhesives to bond to particular substrates.

The A-1100 Amino Silane is formulated to work with epoxies like HXTAL to help them bond more securely to glass substrates.

It does this by chemically altering the structure of the glass at the contact point of the Amino Silane and the glass. This allows the chemical structure of the HXTAL epoxy to bond more securely to the silica in the glass forming a more permanent bond.

The A-1100 Amino Silane that we sell is a mixture of 1% Amino Silane and a Reagent grade 99% pure Isopropyl Alcohol. When applied to a glass surface, the Isopropyl Alcohol evaporates off and leaves a thin layer of the Amino Silane on the glass.

Many customers refer to A-1100 as a cleaning agent, but this is not really correct. We highly recommend cleaning your glass well before applying the A-1100. While the Isopropyl Alcohol may clean some of the glass, it is not really a cleaning agent but an adhesion promotor so it should be applied after your glass has been cleaned with something like Whiting.

Once the A-1100 is applied to the glass surface, you can either leave it on the glass and proceed with bonding your pieces with HXTAL or you can wipe the glass clean again before bonding. Once the A-1100 has been on the glass it will permanently change the checmical structure of the surface of the glass so it doesn’t have to remain on the glass. It will not harm your joint visibility of the joint to let the A-1100 remain on the glass surface before bonding though.

We highly recommend using A-1100 for any bonding that will have a large laminated area or joint or any piece that will be under weight or stress at the joint line.

Expanded Grinding Range

If you haven’t used our resin diamond smoothing wheels before, you should treat yourself to a fantastic way to finish off both batuto, lens work, and flat surface work.

The hub is a blank extruded urethane core that maintains shape and profile even under heavy use and the rim is coated with a resin bonded diamond material. The same material we use on our flat laps is used to coat the rim of the radiused or flat wheel.

These wheels give an unsurpassed cleaning ability on pre-ground surfaces, moving from rough cleanup to fine pre-polish quickly and efficiently.

Recently we have added to our standard routine of 220 grit, 325 grit, and 600 grit a rougher 100 grit option in both our radiused and flat edged smoothing wheels.

This gives the ability to do a very quick clean up on your glass to remove a multitude of stray scratches and deeper penetration of the glass from earlier steps. A great way to prep the surface for further pre-polish and finish up with a quick and easy final polish.

We can even make these wheels in custom sizes and profiles for you.
