Kommerling GD 116 is a 2-component, solvent-free, liquid polymer (LP) polysulfi de sealant. Kommerling GD 116 demonstrates high strength and elasticity, and is a lower odor polysulfide. It has excellent adhesion to clean surfaces such as glass, aluminum, galvanized and stainless steel.

Basic Use

Kommerling GD 116 is designed to be used as a secondary

edge sealant for dual-seal insulating glass units and is widely

used in the manufacture of high-end wood windows.

Kommerling GD 116 demonstrates excellent adhesion to glass

surfaces and most IG spacer systems including aluminum,

anodized aluminum, stainless steel, and tin plated steel. It

has been formulated to work in hand-gunning as well as fully

automated robotic application.

Kommerling GD 116 is resistant to oils, solvents, and a

wide-array of chemicals and thus provides excellent protection

against IG unit failure caused by incompatibility with glazing

materials. Due to it’s impermeability to most solvents, oils, and

plasticizers, Kommerling GD 116 is particularly suited for

application with non-rigid warm-edge spacer systems such as

TPS®, pre-extruded butyl spacers, or foam based spacer

systems. Kommerling GD 116 is compatible with all

commercially available PIB based primary sealants.

Typical application rates are a minimum 4.0mm depth for

gas-fi lled IG units. (However, when determining sealant

volume, unit size, weight, and glazing system design need to

be evaluated for proper IG assembly design.)

  Limitations

• High- viscosity Kommerling GD 116 requires a Graco Hydra-Mate equipped with King air motor. Graco Bulldog^® motors normally do not pump a sufficient volume of Kommerling GD 116 for high-volume production. Kommerling GD 116 pumps very well on all European IG application equipment.

• IG produced with Kommerling GD 116 or any LP Polysulfide should not be used for direct glazing (curtain wall) applications or in applications where the sealant is exposed to direct UV light. Kommerling GD 116 is intended for framed insulating glass applications. 

Application

Substrate Preparation: The surfaces to be bonded must be dry, clean and free from dust and grease. Glass surfaces should be thoroughly cleaned by hand or machine with non-film forming, low residue detergent and rinsed thoroughly with clean hot water.

Blending: When using automatic mixers observe the correct setting of the dosing cylinder. The mixing ratio according to volume is 10:1. The two-component mixture must be applied within approximately 20 minutes (pot life at 23^oC/ 73^oF). Prepare only the amount that can be applied within this period of time. As temperature increases, pot life decreases. General pot life date for B20 is as follows:

20 minute pot life at 20^oC (68^oF) material temperature

10 minute pot life at 30^oC (86^oF) material temperature

5 minute pot life at 40^oC (104^oF) material temperature

Important: if mixing ratio is over-catalyzed in excess of 10:1.1 by volume, poor mechanical properties may result. If mixing ratio is under-catalyzed in excess of 10:0.8 by volume, the final product properties will be only slightly affected. However, the pot-life will be altered in both instances.

Curing: Kömmerling GD 116 should not be applied below 10^oC (50^oF). The curing speed of Kömmerling GD 116 depends on the ambient temperature.

• At 50^oC (40^oF) the curing times can triple
• At 30^oC (86^oF) curing times are shortened by 50%
• A tack free surface is reached after ~ 1-2 hours with the B65 hardener at 23^oC (73^oF) and ~ 15-25 minutes with B20.

Newly fabricated insulating glass units must not be exposed to low temperatures or rain until the desiccant has been able to sufficiently dry the air space to prevent condensation on the glass panes. After 3 hours of pre-drying, the risk is minimal.

Clean Up: Citrus based solvents can be used to clean tools and equipment immediately after use to remove fresh uncured material.

Equipment: The follwoing equipment is suitable for applying Kömmerling GD 116:

GRACO hydra-Mate Shovel Pumps equipped with King Air motors, Reinhardt Technik Pumps, Schwartz, and Lisec & Bystronic manual and semi-automated lines.
