Product Desciption
Polyurethane 518AB
Application
518AB is a two components polyurethane system with the mixing ratio of 1:1, can be cured under normal temperature and high temperature, it forms a very high gloss and transparent coating to its applications such as nameplate, signage and decorations. It is specially designed for the applications requires a soft and flexible clear coating. After cured, it will has a very good features of UV resistance and weather resistance, can be for outdoor use, and can meet the strict requirements for car raw materials, will not yellowing for about 3 to 5 years for outdoor use.
Components
518A: Polyhydric alcohol
518B: Isocyanate
518AB can be operated both by hand and machine.
Features
1, With long pot life and fast heat curing to save time.
2, With low viscosity and good natural defoaming, come to a high gloss and bright surface after cured, without ripple.
3, Very high transparency, with good elasticity and bonding strength.
4, With very good weather and UV resistance for outdoor use, can be used at the temperature of 0 ºC to 100 ºC.
Properties before Hardening
Operation
Hand operation process( long pot life and curing slowly):
1, Place 518A and 518B at the temperature of 15 to 25 ºC, relative humidity lower than 70% for 12hours.
2, Well prepared the products you need to apply the 518AB such as the PVC signage/nameplate, metal signage/nameplate, put them into the oven to heat at the temperature of about 60ºC to clear the moisture on the surface.
3, Totally clear the dust and the oil on the surface of the signage/nameplate.
4, Weigh the 518A and the 518B by 1:1, and fully stir it.
5, Clear the bubbles by vacuum machine(the mixture will not have bubble at the -0.1 vacuum)
6, Take a clean syringe to draw the mixture and drop it to the surface of the well prepared signage/nameplate. Normally the thickness is 2mm.
7, Look at the glue in 5 minutes, if there is some bubbles, use a pin to break the bubbles, or if there is some area that has not been covered by glue, use the pin lead it.
8, Put the finished products in the oven at the temperature of about 60 to 80ºC, it will cured in 2 to 3.5 hours.
Machine operation process:
1, Place 518A and 518B at the temperature of 15~ 25ºC, relative humidity lower than 70%, and no-dust environment for more than 96 hours to remove the bubbles caused during the transportation.
2, Input the pump, sealed and fixed it, keep it for 12hours.
3, Place the signage/nameplate to a flat place, and fix it.
4, Clear the dust and oil on the signage/nameplate surface.
5, Clean the pipeline, mix container and the head with dichloromethane.
6, To clean up the air in the pipeline, mix container, and the head.
7, Drop the glue onto the signage/nameplate surface.
8,Use a pin to lead the glue and remove the bubbles by it.
9, Place the signage/nameplate at the temperature of 60ºC.
10, It will cured at about 2~4 hours.
Properties after Hardening
Packing
PE bucket(5kgs/bucket or 20kgs/bucket)
Storage And Shelf Life
1, Store at the temperature of 15~25°C, under the humidity of 70%. Avoid sunlight, high temperature or high humidity environment.
2, The feature of 518A maybe affected if contact with air, closed the 518A tightly after used. And 518A/B will absorb the moisture in the air easily, strictly avoid this happens.
3, When the mixture is more than 100g, the pot lift will be much shorter.
4, This is non-hazardous chemical, can transported as normal chemicals.
5, Better to clean the water content of 518B by vacuum before use.
