LUMISIL® 105 HP A/B is a 2-part silicone gel (1:1) that is
cured by heat conditions for displays and ´High penetration grade´ of LUMISIL 105.


  • Self-leveling with low viscosity
  • Longer pot life than conventional thermal grade as low Temperature curable OCR
  • Excellent for Plastic application with high Elongation and gel structure
  • Excellent transparency
  • Minimized shrinkage

Surface preparation
All surfaces must be clean and free of contaminants
that will inhibit the cure of LUMISIL® 105 HP A/B.

Examples of inhibiting contaminants are sulfur-containing
materials, plasticizers, urethanes, amine-containing materials,
and organometallic compounds – especially organotin compounds.

If a substrate’s ability to inhibit cure is unknown, a small-scale test
should be run to determine compatibility.

LUMISIL® 105 HP A/B can be mixed through a 24 or 32 elements static mixer as a standard.

Curing speed can be adjusted by temperature and
time. Heat can accelerate the curing process.
We recommend running preliminary tests to optimize
conditions for particular applications. Comprehensive
processing instructions are given in below.

60'C / 3hr or 70'C / 2hr at 300 μm standard thickness

Tack free time can be increased or decreased
depending on the applied temperature.


  • 1 KG Bottle PE
  • 9 KG Bottle PE
  • 20 KG Hobbok


LUMISIL® 105 HP A and LUMISIL® 105 HP B should
be stored between 5 °C and 30 °C and below 60%RH
in the tightly closed original container.

The 'Best use before end' date of each batch appears
on the product label.

Shelf life

LUMISIL® 105 HP A : 1 year

LUMISIL® 105 HP B : 1 year


Storage beyond the date specified on the label does
not necessarily mean that the product is no longer
usable. In this case however, the properties required
for the intended use must be checked for quality
assurance reasons.
