New formula for Granite, Silestone, Caesarstone, Zodiaq, Cambria and Eco sufaces

Seaming Adhesive for quartz and granite

Whether you are fabricating Corian, Cambria or Natural Granite: the next generation of Seam-it adhesive is designed to produce faster curing, effective bonds in ready to use colors.

One of the properties of stone that makes it such a challenge from an adhesive standpoint is its ability to conduct heat.  When you place your hand on a granite or quartz countertop in a house it always feels cold, even if the ambient air is quite warm. The high thermal conductivity of stone causes the heat to be pulled away from your hand leaving the countertop to feel cold to the touch.  This phenomenon is known as “Heat Sink”. The same thing happens to the adhesive in a seam or a lamination. The adhesive needs a greater amount of heat energy to cure, and it is important that the “heat sink” effect is considered when formulating an effective product for stone.

One way to do this is to use a “hot” activator and overpower the thermal conductivity of the stone- effectively pushing the cure through. While this can be effective, there are usually a couple of undesirable side effects.

First, using a “hot” activator produces higher cure temperatures and may discolor some of the lighter shades. Second, a lower overall bond strength is usually the end result. This is especially true in Solid Surfaces due to the unbalanced nature of the formulation.

A better, although more difficult approach, is to formulate based on carefully measured polymeric chain chemistry, keeping the peak exothermic temperature within an acceptable range while reducing the overall cure time and maintaining an effective bond strength.

The results speak for themselves. Give us a call or order a sample of the new formula today.

  1. Hi,
    I have to do a repair on a corian sink . the front skirt of corian is 1/2 ” x 3 1/2″ x 28″. I have to glue the half inch edge to the bottom of the sink. I think I will also glue a backer to provide a stronger fix. What product do you recommend?
    Thanks,
    Rick

    • Hi Rick,

      Do you happen to know the color of the sink? Corian has a couple standard colors to choose from and having this information is critical to get the best match when using a seaming product.
