Polyurethane hot melt, more commonly known as PUR, is an adhesive that shares many characteristics of traditional glue sticks and bulk hot melt.
• PUR hot melt adhesive 3513-W has good initial viscosity, fast positioning, short holding time. After gluing and laminating, it directly participates in the subsequent process to improve production efficiency.
• PUR hot melt adhesive 3513-W has the characteristics of waterproof, shock resistance, pressure resistance, good impact resistance, high bonding strength, good high and low temperature resistance and so on.
• PUR hot melt adhesive 3513-W has the features of solvent-free, non-irritating, non-toxic and harmless to human body, It can conform with EU environmental protection requirements.
PUR hot melt adhesive 3513-W is very strong adhesion to metal, plastic, aluminum, glass, wood, PP, PC, ABS, etc., and the effective time of bonding is long.

PUR3513-W hot melt adhesive can be used on special hot melt adhesive equipment, with various operation methods. Such as: manual and automatic spray guns, platen automatic spray guns, roller coating, spray coating, etc.
• PUR3513-W hot melt adhesive should avoid collision and heavy pressure during transportation and loading and unloading, and prevent it from being unusable due to deformation and damage of the packaging.
• The unopened Pur glue 3513W should be stored in a cool and dry place at room temperature, which can be stored for 3-6 months, avoiding humid environment.
PUR hot melt adhesive 3513-W can be well cured at the temperature is 22℃~28℃, and the relative humidity is 50~90%. If the final performance of the product is tested, we suggest that the bonded product should be best after 5-7 days, depending on the moisture content of the substrate. , the air permeability of the substrate and the temperature and humidity of the environment.
1. PUR hot melt adhesive 3513-W is suitable for the standard coating system of one-component moisture reactive polyurethane hot-melt adhesive (PUR) adhesive. We recommend the standard working temperature in the range of 120℃~150℃. The coating method is different, and the use temperature should also be adjusted appropriately.
2. Melt stability Excessive temperature (>150 ℃) during prolonged shutdown should be avoided.
3. We recommend: If the downtime exceeds 40 minutes, it is best to lower the temperature of the heating system of the melting equipment to 80-90 °C for heat preservation, and adjust the temperature to the normal working temperature during normal production. It is recommended to turn off the heating system and turn on the power for heating 10 minutes before use.
4. The mechanical gluing part should preferably be equipped with an exhaust hood, which can discharge the trace amount of smoke (isocyanate) generated by the PUR hot melt adhesive to the outside during heating, so as to prevent the workers from having adverse reactions when they operate for a long time, generally there will be coughing , tearing eyes and other symptoms.
