Top Weather Proof Water Proof Car Window Glass Installation Fix Adhesive Seal for Windshield Repair
Substrate: PU polymer
DM221 is a one-component polyurethane sealant based on PU polymers, moisture curing type. The curing speed of mortar is related to the temperature and humidity of the environment. Under high-temperature or high-humidity conditions, it will be quickly crusted. Low-temperature and low-humidity will delay the curing process. The final curing time is also related to the thickness of the glue applied.
DM221 is a special sealant suitable for bonding and sealing of vehicle windshield and vehicle body. It has features of moderate modulus, flexibility and with strong adhesion, damping performance, good elongation, and good resilience. And the sealant is suitable for the porous and non-porous materials with good adhesion, can be coated with paint and has other outstanding features, is a high-performance general-purpose elastic sealant.
Features & Advantages

DM221 is suitable for elastic sealing of various substrate joints, including stainless steel, aluminum, copper, PVC, polyester, ceramics, wood, coating, etc., but not suitable for PP and PTFE materials. It plays the role of bonding, sealing, shock absorption and waterproofing in the automotive industry.
l It can be used for bonding, sealing, shock absorption and waterproofing of glass and metal sheet such as cars, passenger cars, new energy vehicles, construction vehicles, electric vehicles, and modified cars. It can also be used to fill gaps between metal sheet and metal sheet, as material of sealing and waterproofing.
l Other industrial or residential applications that require bonding, sealing, shock absorption, and waterproofing.
l The bonded surface must be clean, dry and free of putty before bonding.
l Substrates that may seep out of oil are not suitable for direct application of sealant.
l For rusted or corroded metal surfaces (such as aluminum oxide, copper, iron oxide rust surface), in order to ensure the bonding effect, the rust on the surface layer needs to be worn off before coating.
l Due to the construction environment, construction methods, and material differences, pre-testing is required before use to ensure adhesion performance.
l The optimal coating temperature is +15 ~ +40°C. When the temperature is low, the extrusion resistance increases, warm up the adhesive before use.
