Unisect 2120 Transparent Polyurethane Resins

Unisect 2120 is a water white transparent polyurethane resin specifically created for use
in the production of labels, and badges.

The resin system, when fully cured, exhibits excellent colour stability and mar resistance
and adhesion to all the types of substrates normally used in the production of badges
and labels.

RESIN SPECIFICATION:

Part A :

• Colour - Water White
• Specific Gravity at 250C - 1.04 ± 0.02
• Viscosity at 250C - 140 ± 15 mPa.s

Part B :

• Colour Water - White
• Specific Gravity at 250C - 1.08 ± 0.02
• Viscosity at 250C - 200 ± 20 mPa.s
• NCO Value - 30.0 ± 0.2 %

Typical Cured Elastometer Properties

• Colour : Water White
• Specific Gravity at 250C : 1.06 ± 0.01
• Mix Ratio By Volume : 2:1 Part A : Part B
• Shore 0D Hardness  : 33 ± 3
• Tensile Strength : 5.5 MPa
• Elongation at Break : 130 %
• Geltime 100 gm Mass at 250C : 12-15 mins
• UV Stability – QUV** No yellowing after 4000 hrs

QUV Weatherometer Test - 8 hrs UV exposure at 600C using lamps with peak emission at 340 nm. followed by 4hrs at 500C and 95% humidity in a continuous cycle.

All of the above tests were carried out on specimens cured at 250C for 7 days.

Although the elastomer is not fully cured for 7 days in practice the material can be
handled without damage after 12-24 hours at 250oC.

 
PACKAGING: Unisect 11LV resin system is available in 5 litre, 25 litre and 200 litre drums and in 50 ml cartridges
