Sealant Usage Estimator

Dow Consumer Solutions offers a full line of performance silicone sealants for structural glazing and weatherproofing applications. Determine the amount of sealants you may need for your project. Estimate the needs based on your own past experience with percent waste on the job. This is an estimate and you should evaluate the compatibility of silicone sealants and primers from Dow Consumer Solutions on each of your particular project needs and substrates. Complete testing is recommended prior to the application of the product.

Primer Usage Calculator

Dow Consumer Solutions offers a full line of high performance primers for sealants. Primers are used to enhance adhesion of sealants to specific substrates. Determine the amount of primer you may need for your project. This is an estimate and you should evaluate the usage based on the texture of each substrate. You should also evaluate the compatibility of silicone sealants and primers from Dow Consumer Solutions on each of your particular project needs and substrates. Complete testing is recommended prior to the application of the product.

Structural Bite Calculators

Dow Consumer Solutions offers a full line of high performance silicone structural glazing sealants. Only silicone sealants are suitable for use in structural glazing applications to attached glass, metal or other panel materials to a metal frame in lieu of gaskets and mechanical attachments. Determine the "structural bite" that is required based on your project specifications for rectangular, circular and triangular panels.

Deadload Calculator

In structural glazing applications, the weight of the panel places constant load upon the sealant, called the "deadload". Structural sealants from Dow Consumer Solutions can support the weight of the panel or glass when used within the guidelines. Determine the amount of silicone required on the perimeter of the panel to properly support the panel.

Glueline Thickness Table

Proper glueline thickness facilitates the installation of sealant and allows reduced stress on the structural joint resulting from differential thermal movement. Calculate the thermal movement differential in two different substrates so that you can identify the appropriat glueline thickness for your project.

 

Calculate BITE, in (mm) Minumum Glueline, in  (mm) Maximum Glueline, in (mm)
0.25 (6.4 mm) 0.25 (6.4 mm) 0.25 (6.4 mm)
0.375 (9.6 mm) 0.25 (6.4 mm) 0.375 (9.6 mm)
0.5 (12.7 mm) 0.25 (6.4 mm) 0.5 (12.7 mm)
0.625 (15.9 mm) 0.25 (6.4 mm) 0.5 (12.7 mm)
0.75 (19.1 mm) 0.25 (6.4 mm) 0.5 (12.7 mm)
0.875 (22.3 mm) 0.3 (7.6 mm) 0.5 (12.7 mm)
1 (25.4 mm) 0.34 (8.7 mm) 0.5 (12.7 mm)
1.25 (31.8 mm) 0.42 (10.7 mm) 0.5 (12.7 mm)
1.5 (38.1 mm) 0.5 (12.7 mm) 0.5 (12.7 mm)

Themal Movement Calculator

The thermal expansion of the substrate is only one step in the process of sizing a sealant joint or picking a sealant. Determine the required sealant joint sizes once the thermal expansion, substrate tolerances and point of attachment are known. Thermal expansion coefficients are used from ASTM C1472.
