Keep-Nut by Specialinsert – You’ll Love the Versatility, Ease of Installation, and Incredible Strength

Press in Self-Anchoring Threaded Inserts Formed of Stainless Steel and Plastic

For those who aren’t aware, these are high strength press-in, self-anchoring, threaded inserts that are rated up to 562 lbs per fastener. They can be used for undermount sinks, wall panels, facades, furniture, and more.

Installation is simple. It involves drilling a shallow, cylindrical hole into the surface to be mounted on, and driving the Keep-Nut into it with a rubber mallet. That’s it. This anchoring system is especially suited for automated shops where all the holes can be plotted on CNC equipment. Once the holes are drilled, the fastener is installed in seconds which saves a lot of time and labor.

Advantages include:

  • Compatibility with thin materials (including 2 cm- down to ⅜” depending on variety used)
  • Shallow hole depth (<¼”) means less drilling in granite, less wear on bits, and less time on equipment
  • Quick and easy installation
  • Incredible strength (up to 562 lbs per fastener)
  • Special drills can be used to prevent cracks from the high heat created when drilling into natural stone. Ask about the CNC and Gas Drill Bit (11.8 and 11.4mm)

The Keep-Nut series are threaded self-anchoring fixing systems for marble, stone, ceramic, artificial stones, sandtones, klinker, laminated HPL. Continue reading

Polytek Offers Amazing Advantages in Architectural Finishes

polytek cast stone Let’s continue shining the spotlight on a new line we’re proud to carry at Chemical Concepts: Polytek. Our customers are thrilled with the huge array of cost-effective, high performance options that using Polytek products offer for cast stone veneer and concrete form liners.

Cast Stone Veneer

For high-volume veneer stone production, we recommend using Polytek room-temperature curing, liquid polyurethane or silicone mold rubbers.

Features and Benefits of Polytek Products for Use with Cast Stone Veneer

Liquid polyurethane or silicone mold rubbers from Polytek:

  • Capture excellent surface detail,
  • Can be completed in a much shorter time frame compared to latex rubber molds (with approximately 16 hour demold times).
  • With proper maintenance, these molds will last for several years and produce thousands of stones.

Aria Vents Blend Seamlessly Into Flooring, Walls, and Ceilings

Have you had an opportunity to take a look at the popular new air vents that Chemical Concepts has been distributing over the last few months? We are proud to carry Aria Vents.

aria vent

With a simplistic modern design, the Aria Vent is a customizable air register that uses surface materials to create a seamless and concealed air vent. Fit for a 4″ x 10″ opening, the Aria vent can be retrofitted to any surface or installed at sub-floor level. The vent also gives the homeowner a more aesthetic look and the enjoyment of not having unsightly metal grids that bend and over time get filthy and hard to clean.

Take note that the Aria vent can be installed in walls and ceilings for air returns. The Aria Vent’s beauty and understated presence comes from being able to install matching flooring material in the vent’s inside tray. Once that’s done, the vent appears to seamlessly blend in with its surroundings. Continue reading

Cold Weather Caulking Hints

In the cold months of winter, many contractors are faced with the question of whether high performance sealants maintain their high performing qualities when the temperatures plummet. Thankfully, standardized guidelines from manufacturers can help you feel very confident that well-chosen sealants will work well in temperatures as low as -40 degrees F. It’s advisable, however, to take into consideration the substrate condition, the total anticipated joint movement, and that the proper type of sealant is selected.

When considering substrate condition, keep in mind two important factors: surface condition and surface temperature. Any moisture on the surface could be an impediment in below-freezing temperatures. And temperature ranges can affect the total anticipated movement the joints are expected to experience.

But the condition you can best control is choosing a sealant that is best suited for cold temperatures. Here are two that we recommend for most circumstances.

Bostik Chem-Calk 915 Sealant

Bostik® Chem-Calk® 915 sealant is a one-component, contractor construction grade, smooth polyurethane sealant capable of dynamic joint movement totaling 50% of original joint geometry. This sealant cures to a tough, flexible rubber when exposed to moisture present in the atmosphere.

Chem-Calk® 915 polyurethane sealant has a consistency like toothpaste. Its physical properties will remain relatively stable over time and in varying weather conditions. Its physical properties are relatively unchanged over a wide temperature range, -40°F to 150°F (-40°C to 66°C).

Comparing One-Component and Two-Component Adhesives

If your business incorporates manufacturing processes that benefit from adhesive usage, you may face the question: is it better to use a one-component adhesive or a two-component adhesive? In other words, will it just be one liquid, or will there be two that are mixed together in some fashion?

Many adhesive users assume that one-component processes are easier to control and are, ultimately, more efficient. Though this may be true in many circumstances, don’t underestimate the flexibility of process that two-component adhesives offer.

One-component adhesives typically cure via moisture, heat, and light. So although the adhesive itself is considered one-component, they usually come with a secondary component: the external factor that affects the cure. Two- component adhesives cure when they are combined and generally require no external factor (like the aforementioned light, heat or moisture.)

Single component adhesives may have a shorter shelf life and require care to protect against moisture, heat or light.

Even On HDPE’s Like Starboard: “The Stuff Works!”

HDPE’s (high density polyethelene – like the popular and widely used King StarBoard®) – are famous for basically being products that nothing wants to stick to. That’s a good thing when it comes to dirt and sediment. But it becomes a challenge when you’re talking about things like most adhesives (which, you know, you want to have stick.)

That’s why we love it when we get feedback like this from one of our customers:

Quick shout out to you. I ordered some of the Chem-Set 6105 Polypro that we had talked about and “tested” it out with some HDPE (StarBoard) remnants I had. No mechanical fastener. Repeatedly beat it with a hammer. Dented the Black ST, the stuff works. Thanks for the info!

Rick at Public Safety industries, San Clemente, CA

After a chat with Andrew on our sales team, Rick took his suggestion and found out that there is indeed one adhesive that will work well with StarBoard – Chem-Set 6105.

Chem-Set 6105 Polyolefin Bonder Chem-Set 6105 Polyolefin Bonder

Chem-Set 6105 is a 2-part, 1:1 toughened acrylic adhesive. It has been developed to bond low surface energy plastics such as polypropylene and polyethylene (e.g. King Starboard) – with no primer or surface treatment required. It can also be used to bond a wide variety of other materials such as metals and composite materials and is ideal for bonding dissimilar surfaces. Continue reading
