Specifications
PUR 3543 Pucons is a one-component, solvent-free moisture-curing modified polyurethane hot melt adhesive with long opening time and high initial adhesion, Low viscosity, high physical force, fast curing, strong adhesion to most plastics (PC,ABS,PMMA), glass, and metals (aluminum alloy, stainless steel).
Applications
It is suitable for cell phone plastic, metal frame bonding. After assembly, the positioning strength can be achieved by pressing 20s, which is very suitable for the application of high stress and rapid positioning

Key characteristics

High initial adhesion and high final strength. 

Reliability of high and low temperature resistance

Long opening time, moderate viscosity, not easy to overflow glue.

High temperature and impact resistance 

Curing definitions 

After assembly, the PUR 3543 will form a strong initial adhesion mainly through physical action. In 24 hours, the strength will increase gradually with the chemical reaction. It is suggested that the strength test be done after 24 hours of curing of glue water.

Because different environment, dispensing quantity, temperature can affect the speed of complete curing of glue, generally the definition of complete curing is that under the condition of fixed amount, with the increase of time, the adhesive strength of glue no longer changes significantly. This event is the time required for the complete curing of glue; 

Safety 

Wear protective gloves and glasses, when removed, be sure to wear Ding Qing gloves, when glue drops on the hand, use a large amount of cold water and soap water cleaning;

Glue heating temperature should not exceed 150℃, heating time should not exceed 8 hours; 

Storage and transportation 

The best storage temperature :8-28℃, long storage temperature over 30℃ will affect the quality of glue, must be stored in dry, constant temperature and humidity;
