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,
l Good water resistance, moisture resistance, water absorption is very low
l Good adhesion to most metals and plastics air conditioning control PCB board filling glue seal;
l Life smart toilet, induction toilet, metal induction garbage can circuit board and magnetic coil of moisture and waterproof potting protection.
