Transparent silicone rubber for mold making

INTRODUCTION

Two component room temperature poly addition curing fluid compound which cures with low shrinkage to a strong flexible mould rubber, it has high temperature and chemcal resistance making it well suited for reducing models with undercuts in polyurethane and epoxy resins..

Main field of application

Vacuum casting Rapid prototyping

Electrical application

Mould making

Special Characteristics

 Different Shore A Hardness available from 28-45

 Fast and non shrink cure at room temperature which could can be accelerate considerable by the application of heat

 Good transparency of the cured rubber

 High tear strength

 reproduce finite details from patterns

TECHNICAL PROPERTIES Appearance (component A) : Translucent Component B (Hardener): clear liquid

Viscosity (cps) : 85000(at +23�C) 800

Mixing ratio (mould rubber Harder) : 10: 1 parts in weight

Work Time (at + 23�C) : 60 to 90 minutes

Demoulding time (at +23�C) : 20 to 24 hours

Specific gravity : 1.220 (at + 23�C))

Hardness (Shore A) at 2mm cured : 40

Tensile Strength kg/cm� (MPA) : 10

Tear strength kgf / cm (KN/M) : 14

Higher temperature and humidity will increase the cure rates and, therefore, reduce work time, lower temperature or humidity will slow the cure time. in standard cured time, the demolding time is 12-24hours. The mold can be used after 48 hours of cure
