TEROSON MS 939 GY 290 ml gray adhesive sealant MS polymer for flexible connections
TEROSON MS 939 GY 290 ml is a gray, single-component adhesive sealant based on a silane-modified polymer.
It is a good choice where the joint must not only connect elements, but also compensate for stresses, material movement, and vibrations. TEROSON MS 939 GY is suitable for bonding and sealing metals and plastics, especially in industrial, transport, and assembly applications.
Applications of TEROSON MS 939 GY
TEROSON MS 939 GY is used for flexible bonding of metals and plastics. The manufacturer indicates, among other things, Bonding side panels and roofs in vehicles and caravans.
The product is also suitable for elastic sealing of seams and joints in the production of cars, wagons, containers, vehicle superstructures, the metal industry, equipment manufacturing, electrical engineering, plastics processing, air conditioning and ventilation.
What distinguishes TEROSON MS 939 GY
The most important feature of TEROSON MS 939 GY is its combination of elasticity, good sag resistance, and UV resistance.
The product is free of solvents, isocyanates, silicones, and PVC. It exhibits good adhesion to many substrates and can be used both indoors and outdoors.
When to choose TEROSON MS 939 GY
Choose TEROSON MS 939 GY if you need a flexible adhesive/sealant for working joints exposed to temperature changes, moisture, UV radiation, or weather conditions.
This product is particularly useful when a standard rigid adhesive would be too inflexible, and the sealant alone would not provide sufficient bonding. The gray color is suitable for applications where the joint is to be less contrasting on metal, technical, or structural elements.
What to pay attention to before use
Surfaces should be dry, clean, and degreased before application.
For plastics and coatings, especially powder coatings, the manufacturer recommends testing. For materials such as PMMA, polycarbonate, and substrates not listed in the documentation, a test application should be performed. The product does not adhere to PE, PP, or PTFE.
How to use TEROSON MS 939 GY
The product should be applied with a cartridge gun. Low temperature of the sealant adhesive increases viscosity and may slow down dispensing, so it is recommended to bring the product to room temperature before use.
Higher temperatures and humidity can accelerate the process, while low temperatures and low humidity can slow it down.
