PU1813 Multi-purpose Polyurethane Sheet Metal Car body Sealant Adhesive 的複本
PU1813 Multi-purpose Polyurethane Sheet Metal Car body Sealant Adhesive
●Maxtech PU1813 is one component moisture curing polyurethane adhesive for all kinds of sheet metal bonding and sealing. Maxtech Multi-purpose polyurethane seam sealers and adhesives are high-strength, flexible bonding agents designed specifically for automotive sheet metal. They permanently seal weld seams, floor pans, door jambs, and wheel wells, preventing water, rust, and exhaust fumes from entering the vehicle while withstanding extreme road.
Maxtech PU1813 is Mainly used for welding seam and sealing of automobile, railway passenger cars, ships, cold storage container, van body of refitted vehicle, etc.
● Waterproof, dustproof sealing of refrigerated container, construction and pipe.
● For vehicle sheet metal repairing, aluminum gusset and bodywork sealing.
Key Material Advantages
Superior Flexibility: Urethane formulations provide a flexible bond that outlasts standard silicone under heavy-duty wear and thermal expansion.
Paintable Surfaces: Most auto body polyurethanes can be scuffed and painted over quickly (often in as little as 30-45 minutes) without cracking or shrinking.
Corrosion Protection: When applied to bare, primed, or painted metal, it provides an impenetrable moisture barrier against weather and vibration
PU 6030 Light yellow translucent Polyurethane potting compound
PU 6030 is a two-component solvent-free polyurethane material at room temperature or heat curing. It is light yellow and transparent after curing. It is used for two-component sealing, filling, flame and other fields. The raw material does not contain heavy metals, green environmental protection, wide process operability, high physical properties of the finished product, and good adhesion to the substrate. Room temperature and heating curing can be, can be deep curing, curing less heat, low shrinkage rate; Excellent
flexibility after curing, with good flame retardant effect.
l Excellent low temperature characteristics, excellent weather resistance
l Excellent flame retardancy, 94 V-0
l Excellent electrical insulation, stability
Typical application
l This product is often used in electronic capacitors, automotive electronic module potting;
l Household appliances such as lampblack stove, microwave oven, rice cooker, washing machine,
