Parameters
- Recommended dosing of the Lukopren Catalyst N2 - 3 wt. %
- Elongation at break280 - 300 %
- Thermal resistance of vulcanizate- 50 to + 180 °C
- Hardness of rubber23 - 25 °ShA
- Viscosity14 Pa.s
- Appearancewhite rubber moulding paste
Molding silicone rubber with higher resistance Lukopren N 5221
- manufacturing of more complex flexible molds with deeper undercuts and highly stressed molds with multiple demolding for subsequent casting of plaster, concrete, artificial stone, wax
(precise replication of surface details, easy demolding) - manufacturing of multi-part thin-walled molds with auxiliary bed
- production of castings, pads, inserts, custom seals
- separation or masking layers
(easily removable due to low substrate adhesion) - encapsulation and potting of electrical equipment
(mechanical and weather resistance)
for rubber vulcanization, precise dosing of Lukopren N 5221 is necessary
Lukopren Catalyst N (more details in the technical sheets below)
vulcanizate has very low adhesion to most substrates (peelable), to enhance it, the use of a primer is necessary (Lukopren Primer A or N)
when making molds, we recommend separating the template for easier demolding; silicone molds due to their self-separating properties do not require separation during use
Lukopren N 5221 rubber paste is easily pigmented using Pigment Pastes
silicone rubber can be easily bonded or glued with single-component adhesive Lukopren S
Thin-layer mold made of Lukopren N 5221 with auxiliary plaster bed
