4030A/4030B polyurethane Domes Resin

 

Above: Resin domed labelling

characteristics

Two-content 4030A/B is a kind of room temperature polyurethane casting material, having no impregnant and volatile inside. It forms glittering and translucent protective surface layer with three-dimensional effect, which is about 1.5-2mm thick. This product can be widely used in various scutcheons, nameplates as well as decorations. After curing, it has excellent weathering resistance and ultraviolet radiation resistance, fulfills the strict material requirements of motor industry. It also can be long used outside and won’t turn yellow more than 3 years. 

components

4030A is polyisocyanate, 4030B is polyalcohol, no matter curing by machine or by hand, the products can meets customer’s requests of different hardness, curing time and viscosity.

technics

Here the techinics can be divides as manual curing and mechanical curing, the former one cures long and solidifies slowly while the later one cures short and solidifies fast.

1manual curing

a、    Keep 4030A/B in the room with the temperature of 15~25 and the humidity < 70% for 24 hours before use. 4030A may rime in low temperature, please warm up till clear liquid

bPut scutcheons on the surface and fix with adhesive tape.

cClean the dust and dirt on scutcheons

dWeigh up 4030A/B correctly, the weight ration is 100: 55. chum up adequately.  

ePump the air of mixture

fCure on the surface of scutcheons

gFlow the liquid all around the surface with needle, and perforate the bubble

hPut the scutcheons in the white room of 15-25 and humidity <70%

iSolidify in 24 hours

 2mechanical curing

   Keep 4030A/B in the room with the temperature of 15~25 and the humidity < 70% for 96 hours before use, thus diseasing the bubbles

   Put pump respectively into 4030A and 4030B, sealed and fixed, leave them still.

Put scutcheons on the surface and fix with adhesive tape.

Clean the dust and dirt on scutcheons

   wash blender, pipe and casting pinhead with dichloromethane

   mix 4030A/B, eliminate bubbles from blender, pipe and casting pinhead 

   cast on the surface of scutcheons

  Flow the liquid all around the surface with needle, and perforate the bubble

  Put the scutcheons in the white room of 15-25 and humidity <70%

Solidify in 24 hours
